112-455: Browline glasses are a style of eyeglass frames where the "bold" upper part holding the lenses resembles eyebrows framing the eyes. They were very popular during the 1950s and 1960s, especially in the US. The glasses were first manufactured by Shuron Ltd in 1947 under the "Ronsir" brand, and quickly emulated by various other manufacturers. The design became the most common style of eyeglasses throughout
224-455: A diffraction limited system, which has an increased depth of field, similar to using a small aperture in photography. This form of correction has many limitations that prevent it from gaining popularity in everyday use. Pinhole glasses can be made in a DIY fashion by making small holes in a piece of card which is then held in front of the eyes with a strap or cardboard arms. Glasses may also house other corrective or assistive devices. After
336-415: A filibuster to prevent its passage. Russell proclaimed, "We will resist to the bitter end any measure or any movement which would tend to bring about social equality and intermingling and amalgamation of the races in our [Southern] states." Strong opposition to the bill also came from Senator Strom Thurmond , who was still a Democrat at the time: "This so-called Civil Rights Proposals [ sic ], which
448-416: A Democrat and staunch segregationist from Virginia , indicated his intention to keep the bill bottled up indefinitely. The assassination of United States President John F. Kennedy on November 22, 1963, changed the political situation. Kennedy's successor as president, Lyndon B. Johnson , made use of his experience in legislative politics, along with the bully pulpit he wielded as president, in support of
560-410: A circular lens called a lens blank. Lens blanks are cut to fit the shape of the frame that will hold them. Frame styles vary and fashion trends change over time, resulting in a multitude of lens shapes. For lower power lenses, there are few restrictions, allowing for many trendy and fashionable shapes. Higher power lenses can distort peripheral vision and may become thick and heavy if a large lens shape
672-587: A coalition of 70 liberal and labor organizations. The principal lobbyists for the Leadership Conference were civil rights lawyer Joseph L. Rauh Jr. and Clarence Mitchell Jr. of the NAACP. After the March on Washington for Jobs and Freedom , on August 28, 1963, the organizers visited Kennedy to discuss the civil rights bill. Roy Wilkins , A. Philip Randolph , and Walter Reuther attempted to persuade him to support
784-511: A compromise bill to be considered. On June 19, the president sent his bill to Congress as it was originally written, saying legislative action was "imperative". The president's bill went first to the House of Representatives , where it was referred to the Judiciary Committee , chaired by New York Democrat Emanuel Celler . After a series of hearings on the bill, Celler's committee strengthened
896-435: A filibuster on a civil rights bill, and only once in the 37 years since 1927 had it agreed to cloture for any measure. The most dramatic moment during the cloture vote came when Senator Clair Engle (D-CA) was wheeled into the chamber. Suffering from terminal brain cancer , unable to speak, he pointed to his left eye, signifying his affirmative " Aye " vote when his name was called. He died seven weeks later. On June 19,
1008-533: A frame that holds them in front of a person's eyes , typically utilizing a bridge over the nose and hinged arms, known as temples or temple pieces, that rest over the ears. Glasses are typically used for vision correction , such as with reading glasses and glasses used for nearsightedness ; however, without the specialized lenses, they are sometimes used for cosmetic purposes. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection on
1120-529: A full-sized welding helmet is inconvenient or uncomfortable. These are often called "flash goggles" because they provide protection from welding flash. Nylon frames are usually used for protective eyewear for sports because of their lightweight and flexible properties. Unlike most regular glasses, safety glasses often include protection beside the eyes as well as in front of the eyes. Sunglasses provide more comfort and protection against bright light and often against ultraviolet (UV) light. To properly protect
1232-525: A long-term change in the demographics of the support for each. President Kennedy realized that supporting this bill would risk losing the South's overwhelming support of the Democratic Party. Both Attorney General Robert F. Kennedy and Vice President Johnson had pushed for the introduction of the civil rights legislation. Johnson told Kennedy aide Ted Sorensen that "I know the risks are great and we might lose
SECTION 10
#17328688382071344-429: A major frame style of the 1960s. In 1971 Shuron sold their sixteen-millionth pair of Ronsirs. However, the general backlash against the culture and fashion of the 1950s and 1960s which had begun with the hippie subculture led to a rapid decline in the popularity of browlines, which had come to carry undesirable conformist connotations. The style remained unpopular through the end of 1978, except among conservatives and
1456-717: A provision establishing a Fair Employment Practices Commission that would ban discriminatory practices by all federal agencies, unions, and private companies. Kennedy called the congressional leaders to the White House in late October 1963 to line up the necessary votes in the House for passage. The bill was reported out of the Judiciary Committee in November 1963 and referred to the Rules Committee , whose chairman, Howard W. Smith ,
1568-473: A recent ophthalmic prescription are required. People who need glasses to see often have corrective lens restrictions on their driver's licenses that require them to wear their glasses every time they drive or risk fines or jail time. Some militaries issue prescription glasses to servicemen and women. These are typically GI glasses . Many state prisons in the United States issue glasses to inmates, often in
1680-432: A separate set of glasses for focusing on close by objects. Reading glasses are available without prescription from drugstores , and offer a cheap, practical solution, though these have a pair of simple lenses of equal power, and so will not correct refraction problems like astigmatism or refractive or prismatic variations between the left and right eye. For the total correction of the individual's sight, glasses complying to
1792-488: A stronghold of the Republican Party by the 1990s. Although majorities in both parties voted for the bill, there were notable exceptions. Though he opposed forced segregation, Republican 1964 presidential candidate, Senator Barry Goldwater of Arizona, voted against the bill, remarking, "You can't legislate morality." Goldwater had supported previous attempts to pass civil rights legislation in 1957 and 1960 as well as
1904-465: A substitute bill that they hoped would overcome it by combining a sufficient number of Republicans as well as core liberal Democrats. The compromise bill was weaker than the House version as to the government's power in regulating the conduct of private business, but not weak enough to make the House reconsider it. Senator Robert Byrd ended his filibuster in opposition to the bill on the morning of June 10, 1964, after 14 hours and 13 minutes. Up to then,
2016-487: A supportive memorandum at the behest of the National Federation of Business and Professional Women . Griffiths also argued that the laws "protecting" women from unpleasant jobs were actually designed to enable men to monopolize those jobs, and that that was unfair to women who were not allowed to try out for those jobs. The amendment passed with the votes of Republicans and Southern Democrats. The final law passed with
2128-627: A violation [of the Constitution], because it would be handling the matter on the basis of race and we would be transporting children because of race." Javits said any government official who sought to use the bill for busing purposes "would be making a fool of himself," but two years later the Department of Health, Education and Welfare said that Southern school districts would be required to meet mathematical ratios of students by busing. The bill divided both major American political parties and engendered
2240-650: A wide range of fashions are available, using plastic, metal, wire, and other materials for frames. Glasses can be marked or found by their primary function, but also appear in combinations such as prescription sunglasses or safety glasses with enhanced magnification. Corrective lenses are used to correct refractive errors by bending the light entering the eye in order to alleviate the effects of conditions such as nearsightedness (myopia) , farsightedness (hypermetropia) or astigmatism . The ability of one's eyes to accommodate their focus to near and distant focus alters over time. A common condition in people over forty years old
2352-404: Is presbyopia , which is caused by the eye's crystalline lens losing elasticity, progressively reducing the ability of the lens to accommodate (i.e. to focus on objects close to the eye). Few people have a pair of eyes that show exactly equal refractive characteristics; one eye may need a "stronger" (i.e. more refracting) lens than the other. Corrective lenses bring the image back into focus on
SECTION 20
#17328688382072464-455: Is "single vision", which has a uniform refractive index . For people with presbyopia and hyperopia , bifocal and trifocal glasses provide two or three different refractive indices, respectively, and progressive lenses have a continuous gradient. Lenses can also be manufactured with high refractive indices, which allow them to be more lightweight and thinner than their counterparts with "low" refractive indices. Reading glasses provide
2576-501: Is a landmark civil rights and labor law in the United States that outlaws discrimination based on race , color , religion, sex, and national origin. It prohibits unequal application of voter registration requirements, racial segregation in schools and public accommodations , and employment discrimination. The act "remains one of the most significant legislative achievements in American history". Initially, powers given to enforce
2688-413: Is also known to have written on the magnifying properties of lenses. The development of the first eyeglasses took place in northern Italy in the second half of the 13th century. Independently of the development of optical lenses, some cultures developed " sunglasses " for eye protection, without any corrective properties. For example, flat panes of smoky quartz were used in 12th-century China , and
2800-517: Is filtered so that each eye receives a slightly different image. The filters only work for the type of signal they were designed for. Anaglyph 3D glasses have a different colored filter for each eye, typically red and blue or red and green. A polarized 3D system on the other hand uses polarized filters. Polarized 3D glasses allow for color 3D, while the red-blue lenses produce an image with distorted coloration. An active shutter 3D system uses electronic shutters . Head-mounted displays can filter
2912-519: Is mistakenly claimed to have encountered eyeglasses during his travels in China in the 13th century. However, no such evidence appears in his accounts. Indeed, the earliest mentions of eyeglasses in China occur in the 15th century and those Chinese sources state that eyeglasses were imported. 1964 Civil Rights Act District of Columbia The Civil Rights Act of 1964 ( Pub. L. 88–352 , 78 Stat. 241 , enacted July 2, 1964 )
3024-439: Is no measurable UV light from computer monitors. The problem of computer vision syndrome (CVS) can result from focusing the eyes on a screen for long, continuous periods. Many times the glasses do not appear to have much of a tint, or, if any, a slight yellow tint, but they may be more heavily tinted. Long hours of computer use (not blue light) may cause eye strain. Many eye symptoms caused by computer use will lessen after
3136-404: Is not yet twenty years since there was found the art of making eyeglasses, which make for good vision ... And it is so short a time that this new art, never before extant, was discovered. ... I saw the one who first discovered and practiced it, and I talked to him." Giordano's colleague Friar Alessandro della Spina of Pisa (d. 1313) was soon making eyeglasses. The Ancient Chronicle of
3248-646: Is the only company to have constantly produced browlines since their inception; Victory Optical shut down for a period in the 1980s–1990s before resuming manufacture in the 2000s. Art-Craft optical still features the Clubman model on their webpage, although the company no longer manufactures the frame, and now only sells remaining parts from the factory. Ray-Ban still produces the Clubmaster. Glasses#Frames Glasses , also known as eyeglasses and spectacles , are vision eyewear with clear or tinted lenses mounted in
3360-404: Is used. However, if the lens is too small, it can drastically reduce the field of view. Bifocal , trifocal , and progressive lenses generally require a taller lens shape to leave room for the different segments while preserving an adequate field of view through each segment. Frames with rounded edges are the most efficient for correcting myopic prescriptions, with perfectly round frames being
3472-601: The 15th Amendment . The legislation was proposed by President John F. Kennedy in June 1963, but it was opposed by filibuster in the Senate. After Kennedy was assassinated on November 22, 1963, President Lyndon B. Johnson pushed the bill forward. The United States House of Representatives passed the bill on February 10, 1964, and after a 72-day filibuster, it passed the United States Senate on June 19, 1964. The final vote

3584-610: The 24th Amendment outlawing the poll tax . He stated that the reason for his opposition to the 1964 bill was Title II, which in his opinion violated individual liberty and states' rights . Democrats and Republicans from the Southern states opposed the bill and led an unsuccessful 60 working day filibuster, including Senators Albert Gore, Sr. (D-TN) and J. William Fulbright (D-AR), as well as Senator Robert Byrd (D-WV), who personally filibustered for 14 hours straight. There were white business owners who claimed that Congress did not have
3696-596: The Civil Rights Act of 1875 of much of its ability to protect civil rights. In the late 19th and early 20th century, the legal justification for voiding the Civil Rights Act of 1875 was part of a larger trend by members of the United States Supreme Court to invalidate most government regulations of the private sector, except when dealing with laws designed to protect traditional public morality. In

The ophthalmic frame is the part of a pair of glasses that is designed to hold
3920-615: The Inuit have used snow goggles for eye protection. The earliest recorded comment on the use of lenses for optical purposes was made in 1268 by Roger Bacon . The first eyeglasses were estimated to have been made in Central Italy , most likely in Pisa or Florence , by about 1290: In a sermon delivered on 23 February 1306, the Dominican friar Giordano da Pisa ( c. 1255 –1311) wrote "It
4032-714: The March on Washington Movement , just before the U.S. entered World War II, President Franklin Roosevelt issued Executive Order 8802 , the first federal anti-discrimination order, and established the Fair Employment Practices Committee . Roosevelt's successor, President Harry Truman , appointed the President's Committee on Civil Rights , proposed the 20th century's first comprehensive Civil Rights Act, and issued Executive Order 9980 and Executive Order 9981 , providing for fair employment and desegregation throughout
4144-606: The Wayfarer Max, a fusion of the then-popular Wayfarer and Clubmaster sunglass models. The style proved unpopular and was quickly phased out. The monobrowline design was resurrected by a variety of manufacturers in the 2010s (chiefly Oakley ) after browlines returned to popularity. Unlike its tenure in the 1980s, monobrowlines proved to be a popular variant among eyeglass wearers in the 2010s. Browline glasses were introduced in 1947 by Jack Rohrbach, then vice-president of Shuron Ltd., an eyeglass company. The first browlines, sold under
4256-465: The "Ronsir" model name, had interchangeable bridges, eyewires, and "brows," allowing wearers to completely customize the size, fit, and color of their glasses. At the time, most frame manufacturers offered a limited number of colors and sizes. The style became popular, and many other companies soon produced their own browline frames. Art-Craft Optical produced the "Art-Rim" brand, which offered designs for men ("Clubman") and women ("Leading Lady"). Throughout
4368-457: The "night mode" of different operating systems, which can usually be activated outside of nighttime hours. The American Academy of Ophthalmology (AAO) does not recommend special eyewear for computer use, although it recommends using prescription glasses measured specifically for computer screen distance (depending on individuals, but possibly 20–26 inches from the face), which are not the same as "blue-light blocking" glasses. The position of

There are claims that single lens magnifying glasses were being used in China during the Northern Song dynasty (960–1127). Robert Grosseteste 's treatise De iride ( On the Rainbow ), written between 1220 and 1235, mentions using optics to "read the smallest letters at incredible distances". A few years later in 1262, Roger Bacon

4704-526: The 1930s to assist people bedbound by chronic illness or spinal injury, recumbent glasses have more recently been marketed not simply as an assistive device but also as 'lazy glasses'. They do not assist with vision, although they can be worn over regular corrective glasses. Yellow-tinted glasses are a type of glasses with a minor yellow tint. They perform a slight color correction, on top of reducing eyestrain from lack of blinking. They may also be considered minor corrective non-prescription glasses. Depending on
4816-597: The 1930s, during the New Deal , the majority of the Supreme Court justices gradually shifted their legal theory to allow for greater government regulation of the private sector under the Commerce Clause, thus paving the way for the federal government to enact civil rights laws prohibiting both public and private sector discrimination on the basis of the commerce clause. Influenced in part by the " Black Cabinet " advisors and

Browlines enjoyed a renaissance as sunglasses in the 1980s before returning to popularity in the 2010s, with the rise of retro style and the hipster subculture. Browline glasses are constructed with the upper portion of the frame thicker than the lower, simulating eyebrows , or otherwise drawing attention to
5040-623: The 1950s, with different manufacturers modifying the original browline design. Art-Craft and Victory Optical introduced browlines with much lighter aluminum caps instead of plastic brows. Shuron began modifying the original browline shape, beginning with the rectangular "Rondon" model, to appeal to individuals of all face shapes. For a period in the 1950s, plastic brows designed to emulate wood grains became popular, with Victory Optical offering models that allowed wearers to fit different caps to coordinate with different clothing. Ultimately, browline glasses accounted for half of all eyeglasses sold and worn in
5152-450: The 1950s. Many famous people from the mid-20th century are pictured wearing browlines, including black liberationist Malcolm X , Kentucky Fried Chicken founder Colonel Sanders , president Lyndon B. Johnson (most notably in his national statement regarding the signing of the 1964 Civil Rights Act ), Vince Lombardi , Josemaría Escrivá , Josip Broz Tito (President of Yugoslavia) and others. Browlines continued to remain popular through
5264-491: The 1960s and the start of the 1970s in the aftermath of the Green v. County School Board of New Kent County (1968) court decision. In June 2020, the U.S. Supreme Court ruled in three cases ( Bostock v. Clayton County , Altitude Express, Inc. v. Zarda , and R.G. & G.R. Harris Funeral Homes Inc. v. Equal Employment Opportunity Commission ) that Title VII of the Civil Rights Act, which barred employers from discriminating on
5376-401: The 1960s, but less so as advances in plastics manufacturing offered even further frame customization via solid plastic eyeglasses, which could now be made in more shapes, sizes, and colors than in the past. Those who wished to wear plastic frames but still liked the browline style flocked to "plastic browlines," plastic glasses with transparent lower portions and solid upper portions, which became
5488-476: The 1960s, six manufacturers dominated the browline market: Shuron, Art-Craft Optical, Victory Optical, American Optical, and Bausch and Lomb (with the Ray-Ban Browline ); each company differentiated their frames through unique plaques on the upper corners of the frames, which sometimes also served to cover the rivets attaching the temples to the frame. The style continued to rise in popularity throughout
5600-585: The 1964 bill in his Report to the American People on Civil Rights on June 11, 1963. He sought legislation "giving all Americans the right to be served in facilities which are open to the public—hotels, restaurants, theaters, retail stores, and similar establishments"—as well as "greater protection for the right to vote". In late July, Walter Reuther , president of the United Auto Workers , warned that if Congress failed to pass Kennedy's civil rights bill,
5712-755: The Civil Rights Act of 1957 did establish the United States Commission on Civil Rights and the United States Department of Justice Civil Rights Division . By 1960, black voting had increased by only 3%, and Congress passed the Civil Rights Act of 1960 , which eliminated certain loopholes left by the 1957 Act. In winning the 1960 United States presidential election , Kennedy took 70% of the African American vote. But due to his somewhat narrow victory and Democrats' narrow majorities in Congress, he

#17328688382075824-611: The Civil Rights Act of 1964 was a breach of the Fourteenth Amendment and also violated the Fifth and Thirteenth Amendments by depriving him of "liberty and property without due process". In Heart of Atlanta Motel v. United States (1964), the Supreme Court held that Congress drew its authority from the Constitution's Commerce Clause, rejecting Rolleston's claims. Resistance to the public accommodation clause continued for years on
5936-503: The Constitution or U.S. law. In essence, this was the controversial "Title III" that had been removed from the 1957 Act and 1960 Act . Civil rights organizations pressed hard for this provision because it could be used to protect peaceful protesters and black voters from police brutality and suppression of free speech rights. Lobbying support for the Civil Rights Act was coordinated by the Leadership Conference on Civil Rights ,
6048-576: The Dominican Monastery of St. Catherine in Pisa records: "Eyeglasses, having first been made by someone else, who was unwilling to share them, he [Spina] made them and shared them with everyone with a cheerful and willing heart." Venice quickly became an important center of manufacture, especially due to using the high-quality glass made at Murano . By 1301, there were guild regulations in Venice governing
6160-590: The Justice Department power to initiate desegregation or job discrimination lawsuits. On June 11, 1963, President Kennedy met with Republican leaders to discuss the legislation before his television address to the nation that evening. Two days later, Senate Minority Leader Everett Dirksen and Senate Majority Leader Mike Mansfield both voiced support for the president's bill, except for provisions guaranteeing equal access to places of public accommodations. This led to several Republican Representatives drafting
6272-563: The President has sent to Capitol Hill for enactment into law, are unconstitutional, unnecessary, unwise and extend beyond the realm of reason. This is the worst civil-rights package ever presented to the Congress and is reminiscent of the Reconstruction proposals and actions of the radical Republican Congress." After the filibuster had gone on for 54 days, Senators Mansfield, Hubert Humphrey , Everett Dirksen , and Thomas Kuchel introduced
6384-555: The Ronsir as Shuron's flagship frame. The original stag had no metal chassis: the lenses were mounted directly to the brow caps via two sets of screws. Although the style was never popular in the United States, it became particularly fashionable in Europe and England in the 1960s as part of Amor's Spotlite line. The modern monobrowline originated in the 1980s, as part of an effort by Bausch and Lomb to diversify their Ray-Ban sunglass collection with
6496-411: The South, but those sorts of states may be lost anyway." Senator Richard Russell, Jr. later warned President Johnson that his strong support for the civil rights bill "will not only cost you the South, it will cost you the election". Johnson, however, went on to win the 1964 election by one of the biggest landslides in American history. The South, which had five states swing Republican in 1964, became
6608-563: The act were weak, but these were supplemented during later years. Congress asserted its authority to legislate under several different parts of the United States Constitution , principally its enumerated power to regulate interstate commerce under the Commerce Clause of Article I, Section 8 , its duty to guarantee all citizens equal protection of the laws under the 14th Amendment , and its duty to protect voting rights under
6720-495: The act, adding provisions to ban racial discrimination in employment, providing greater protection to black voters, eliminating segregation in all publicly owned facilities (not just schools), and strengthening the anti-segregation clauses regarding public facilities such as lunch counters. They also added authorization for the Attorney General to file lawsuits to protect individuals against the deprivation of any rights secured by
6832-544: The amendment. Along with Representative Martha Griffiths , he was the amendment's chief spokesperson. For 20 years, Smith had sponsored the Equal Rights Amendment (with no linkage to racial issues) in the House because he believed in it. For decades he had been close to the National Woman's Party and its leader Alice Paul , who had been a leading figure in winning the right to vote for women in 1920, co-authored

#17328688382076944-408: The basic fixed frame with another pair of lenses (optional), that are connected by four-bar linkage . For example, sun lenses could be easily lifted up and down while mixed with myopia lenses that always stay on. Presbyopia lenses could be also combined and easily removed from the field of view if needed without taking off glasses. These glasses are often used for drivers going through tunnels, with
7056-586: The basis of sex, precluded employers from discriminating on the basis of sexual orientation or gender identity . Afterward, USA Today stated that in addition to LGBTQ employment discrimination, "[t]he court's ruling is likely to have a sweeping impact on federal civil rights laws barring sex discrimination in education, health care, housing and financial credit." Title I barred unequal application of voter registration requirements. This title did not eliminate literacy tests , which acted as one barrier for black voters, other racial minorities, and poor whites in
7168-442: The bill because he opposed civil rights for Black people and women or attempted to support their rights by broadening the bill to include women. Smith expected that Republicans, who had included equal rights for women in their party's platform since 1944, would probably vote for the amendment. Historians speculate that Smith was trying to embarrass northern Democrats who opposed civil rights for women because labor unions opposed
7280-487: The bill would have been referred to the Senate Judiciary Committee , which was chaired by James O. Eastland , a Democrat from Mississippi , whose firm opposition made it seem impossible that the bill would reach the Senate floor. Senate Majority Leader Mike Mansfield took a novel approach to prevent the Judiciary Committee from keeping the bill in limbo: initially waiving a second reading immediately after
7392-418: The bill's opponents' most damaging arguments was that once passed, the bill would require forced busing to achieve certain racial quotas in schools. The bill's proponents, such as Emanuel Celler and Jacob Javits , said it would not authorize such measures. Leading sponsor Hubert Humphrey wrote two amendments specifically designed to outlaw busing. Humphrey said, "if the bill were to compel it, it would be
7504-468: The bill. In his first address to a joint session of Congress on November 27, 1963, Johnson told the legislators, "No memorial oration or eulogy could more eloquently honor President Kennedy's memory than the earliest possible passage of the civil rights bill for which he fought so long." Judiciary Committee chairman Celler filed a petition to discharge the bill from the Rules Committee; it required
7616-518: The brows were constructed from aluminium; following the style's resurgence in the 2000s, browlines made wholly out of one type of metal with less pronounced brow portions became popular. Monobrowlines are a variant of browlines in which the bridge is contiguous with the caps, creating a solid, unbroken line across the top of the frame. The style dates back to the Shuron Stag, a browline prototype, which enjoyed some brief popularity before being replaced by
7728-513: The cardinal Hugh de Saint-Cher reading in a scriptorium . Another early example would be a depiction of eyeglasses found north of the Alps in an altarpiece of the church of Bad Wildungen , Germany, in 1403. These early glasses had convex lenses that could correct both hyperopia (farsightedness), and the presbyopia that commonly develops as a symptom of aging . Although concave lenses for myopia (near-sightedness) had made their first appearance in
7840-488: The clause. Representative Carl Elliott of Alabama later said, "Smith didn't give a damn about women's rights", as "he was trying to knock off votes either then or down the line because there was always a hard core of men who didn't favor women's rights", and according to the Congressional Record , laughter greeted Smith when he introduced the amendment. Smith asserted that he was not joking and sincerely supported
7952-764: The company, these computer or gaming glasses can also filter out high energy blue and ultra-violet light from LCD screens , fluorescent lighting , and other sources of light. This allows for reduced eye-strain. These glasses can be ordered as standard or prescription lenses that fit into standard optical frames. By the end of the 2010s, eyeglasses that filter out blue light from computers , smartphones and tablets are becoming increasingly popular in response to concerns about problems caused by blue light overexposure. The problems claimed range from dry eyes to eye strain , sleep cycle disruption, up to macular degeneration which can cause partial blindness. They may also block out ultraviolet (UV) radiation. However, there
8064-630: The compromise bill passed the Senate by a vote of 73–27, quickly passed through the conference committee , which adopted the Senate version of the bill, then was passed by both houses of Congress and signed into law by Johnson on July 2, 1964. Totals are in Yea – Nay format: Original House version: Cloture in the Senate: Senate version: Senate version, voted on by the House: Note that "Southern", as used here, only refers to members of Congress from
8176-481: The constitutional authority to ban segregation in public accommodations. For example, Moreton Rolleston, the owner of a motel in Atlanta, Georgia, said he should not be forced to serve black travelers, saying, "the fundamental question [...] is whether or not Congress has the power to take away the liberty of an individual to run his business as he sees fit in the selection and choice of his customers". Rolleston claimed that

Emulating the Civil Rights Act of 1875 , Kennedy's civil rights bill included provisions to ban discrimination in public accommodations and enable the U.S. Attorney General to join lawsuits against state governments that operated segregated school systems, among other provisions. But it did not include a number of provisions civil rights leaders deemed essential, including protection against police brutality, ending discrimination in private employment, and granting
8512-466: The development of the transistor in the 1940s, combined eyeglass-hearing aids became popular. With thick-rimmed glasses the fashion at the time, a hearing aid could be concealed in the temple part of the frame. These fell out of fashion after the 1970s, but there are still occasions when combined eyeglass-hearing aids may be useful. Safety glasses are worn to protect the eyes in various situations. They are made with break-proof plastic lenses to protect
8624-554: The elderly. Demand suddenly rose between 1978 and 1980, as the anti-disco backlash affected the until-then popular Aviators and Teashades, which became associated with the fashion of the time. The rise also boosted the Wayfarer model, which like the Ronsirs were about to be phased out in the early 1980s. About 12,000 pairs were sold in 1982. Five years earlier fewer than 5,000 were purchased. However, by 1987 figures amounted for over 500,000. In
8736-611: The eye from flying debris or other matter. Construction workers, factory workers, machinists and lab technicians are often required to wear safety glasses to shield the eyes from flying debris or hazardous splatters such as blood or chemicals. As of 2017, dentists and surgeons in Canada and other countries are required to wear safety glasses to protect against infection from patients' blood or other body fluids. There are also safety glasses for welding , which are styled like wraparound sunglasses, but with much darker lenses, for use in welding where
8848-455: The eyes from the dangers of UV light, sunglasses should have UV-400 blocker to provide good coverage against the entire light spectrum that poses a danger. Light polarization is an added feature that can be applied to sunglass lenses. Polarization filters are positioned to remove horizontally polarized rays of light, which eliminates glare from horizontal surfaces (allowing wearers to see into water when reflected light would otherwise overwhelm
8960-550: The federal government and the armed forces. The Civil Rights Act of 1957 , signed by President Dwight D. Eisenhower on September 9, 1957, was the first federal civil rights legislation since the Civil Rights Act of 1875 to become law. After the Supreme Court ruled school segregation unconstitutional in 1954 in Brown v. Board of Education , Southern Democrats began a campaign of " massive resistance " against desegregation, and even
9072-458: The few moderate white leaders shifted to openly racist positions. Partly in an effort to defuse calls for more far-reaching reforms, Eisenhower proposed a civil rights bill that would increase the protection of African American voting rights. Despite having a limited impact on African-American voter participation, at a time when black voter registration from 0% (in 11 counties) to less than 5% (in 97 counties) despite being majority-Black counties,
9184-421: The first Equal Rights Amendment, and had been a chief supporter of equal rights proposals since then. She and other feminists had worked with Smith since 1945 to find a way to include sex as a protected civil rights category, and felt now was the moment. Griffiths argued that the new law would protect black women but not white women, and that that was unfair to white women. Black feminist lawyer Pauli Murray wrote
9296-476: The first reading, which would have sent it to the Judiciary Committee, he took the unprecedented step of giving the bill a second reading on February 26, 1964, thereby bypassing the Judiciary Committee, and sending it to the Senate floor for immediate debate. When the bill came before the full Senate for debate on March 30, 1964, the " Southern Bloc " of 18 southern Democratic Senators and lone Republican John Tower of Texas, led by Richard Russell (D-GA), launched
9408-557: The floorboards at Kloster Wienhausen , a convent near Celle in Germany; they have been dated to circa 1400. The world's first specialist shop for spectacles—what we might regard today as an optician —opened in Strasbourg (then Holy Roman Empire , now France) in 1466. The 17th-century claim by Francesco Redi that Salvino degli Armati of Florence invented eyeglasses in the 13th century has been exposed as erroneous. Marco Polo
9520-414: The form of clear plastic aviators. Adjustable-focus eyeglasses might be used to replace bifocals or trifocals, or might be used to produce cheaper single-vision glasses (since they do not have to be custom-manufactured for every person). Pinhole glasses are a type of corrective glasses that do not use a lens. Pinhole glasses do not actually refract the light or change focal length. Instead, they create
9632-461: The ground, especially in the South. When local college students in Orangeburg, South Carolina, attempted to desegregate a bowling alley in 1968, they were violently attacked, leading to rioting and what became known as the " Orangeburg massacre ." Resistance by school boards continued into the next decade, with the most significant declines in black-white school segregation only occurring at the end of
9744-425: The late 2000s and early 2010s were seen wearing browlines, including Mad Men , Heroes (on which the style worn by character Noah Bennet was erroneously identified as " horn rimmed glasses "), American Horror Story , and CSI: Crime Scene Investigation . By 2013 of the major companies that produced browlines during the height of their popularity, only Shuron and Victory Optical still manufacture them. Shuron
9856-463: The lenses in the proper position. Ophthalmic frames come in a variety of styles, sizes, materials, shapes, and colors. Various metals and alloys may be used to make glasses, such as gold, silver, aluminum, beryllium , stainless steel , titanium , Monel , and nickel titanium . Natural materials such as wood, bone, ivory, leather and semi-precious or precious stones may also be used. Corrective lenses can be produced in many different shapes from
9968-495: The lenses; however, special prescription sunglasses can be made. People with conditions that have photophobia as a primary symptom (like certain migraine disorders) often wear sunglasses or precision tinted glasses, even indoors and at night. Specialized glasses may be used for viewing specific visual information, for example, 3D glasses for 3D films ( stereoscopy ). Sometimes glasses are worn purely for fashion or aesthetic purposes. Even with glasses used for vision correction,
10080-473: The light more tolerable. Sunglasses may also have corrective lenses, which requires a prescription. Clip-on sunglasses or sunglass clips can be attached to another pair of glasses. Some wrap-around sunglasses are large enough to be worn over another pair of glasses. Otherwise, many people opt to wear contact lenses to correct their vision so that standard sunglasses can be used. The double frame uplifting glasses have one moving frame with one pair of lenses and
10192-517: The loss and breaking of the glasses. Sunglasses allow for better vision in bright daylight and are used to protect one's eyes against damage from excessive levels of ultraviolet light . Typical sunglasses lenses are tinted for protection against bright light or polarized to remove glare; photochromic glasses are clear or lightly tinted in dark or indoor conditions, but turn into sunglasses when they come into contact with ultraviolet light. Most over-the-counter sunglasses do not have corrective power in
10304-415: The measure had occupied the Senate for 60 working days, including six Saturdays. The day before, Humphrey, the bill's manager, concluded that he had the 67 votes required at that time to end the debate and the filibuster. With six wavering senators providing a four-vote victory margin, the final tally stood at 71 to 29. Never before in its entire history had the Senate been able to muster enough votes to defeat
10416-406: The mid-15th century, it was not until 1604 that Johannes Kepler published the first correct explanation as to why convex and concave lenses could correct presbyopia and myopia. Early frames for glasses consisted of two magnifying glasses riveted together by the handles so that they could grip the nose. These are referred to as "rivet spectacles". The earliest surviving examples were found under
10528-508: The mid-1980s Bruce Willis wore a pair of Shuron Ronsirs with tinted lenses on the series Moonlighting , leading to a surge in demand for browline sunglasses. In response, Ray-Ban , which already dominated the sunglasses market with their Wayfarers and Aviator sunglasses , introduced the Clubmaster, a traditional browline frame with sunglass lenses, and the Wayfarer Max, a Wayfarer shaped-and-sized browline. The Clubmaster went on to become
10640-530: The most efficient. Before the advent of eyeglasses as a fashion item, when frames were constructed with only functionality in mind, virtually all eyeglasses were either round , oval , panto, rectangular , octagonal , or square . It was not until glasses began to be seen as an accessory that different shapes were introduced to be more aesthetically pleasing than functional. Scattered evidence exists for use of visual aid devices in Greek and Roman times, most prominently
10752-460: The retina. They are made to conform to the prescription of an ophthalmologist or optometrist . A lensmeter can be used to verify the specifications of an existing pair of glasses. Corrective eyeglasses can significantly improve the life quality of the wearer. Not only do they enhance the wearer's visual experience, but can also reduce problems that result from eye strain, such as headaches or squinting. The most common type of corrective lens
10864-423: The sale of eyeglasses and a separate guild of Venetian spectacle makers was formed in 1320. In the fourteenth century, they were very common objects: Francesco Petrarca says in one of his letters that, until he was 60, he did not need glasses, and Franco Sacchetti mentions them often in his Trecentonovelle . The earliest pictorial evidence for the use of eyeglasses is Tommaso da Modena 's 1352 portrait of
10976-549: The same Congress had passed the Equal Pay Act of 1963 , which prohibited wage differentials based on sex. The prohibition on sex discrimination was added to the Civil Rights Act by Howard W. Smith , a powerful Virginia Democrat who chaired the House Rules Committee and strongly opposed the legislation. Smith's amendment was passed by a teller vote of 168 to 133. Historians debate whether Smith cynically attempted to defeat
11088-639: The scene). Polarized sunglasses may present some difficulties for pilots since reflections from water and other structures often used to gauge altitude may be removed. Liquid-crystal displays emit polarized light, making them sometimes difficult to view with polarized sunglasses. Sunglasses may be worn for aesthetic purposes, or simply to hide the eyes. Examples of sunglasses that were popular for these reasons include tea shades and mirrorshades . Many blind people wear nearly opaque glasses to hide their eyes for cosmetic reasons. Many people with light sensitivity conditions wear sunglasses or other tinted glasses to make
11200-430: The sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation . Glasses are worn for eye protection in some sports, such as squash . Glasses wearers may use a strap to prevent the glasses from falling off. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck to prevent
11312-681: The signal electronically and then transmit light directly into the viewer's eyes. Anaglyph and polarized glasses are distributed to audiences at 3D movies . Polarized and active shutter glasses are used with many home theaters. Head-mounted displays are used by a single person, but the input signal can be shared between multiple units. Glasses can also provide magnification that is useful for people with vision impairments or specific occupational demands. An example would be bioptics or bioptic telescopes which have small telescopes mounted on, in, or behind their regular lenses. Newer designs use smaller lightweight telescopes, which can be embedded into
11424-457: The support of a majority of House members to move the bill to the floor. Initially, Celler had a difficult time acquiring the signatures necessary, with many Representatives who supported the civil rights bill itself remaining cautious about violating normal House procedure with the rare use of a discharge petition. By the time of the 1963 winter recess, 50 signatures were still needed. After the return of Congress from its winter recess, however, it
11536-414: The third best selling sunglasses style of the 1980s, behind the Wayfarer and aviator. Bob Geldof can also be seen wearing a pair of browline sunglasses that look to be Clubmasters in the 1982 Pink Floyd movie The Wall . Browlines (and plastic glasses in general) were deeply affected by the backlash against the 1980s consumer culture, and carried a variety of stigmas during the 1990s, variously identifying
11648-423: The upper frame serving as sunglasses and the second frame as transparent lenses. The illusion of three dimensions on a two-dimensional surface can be created by providing each eye with different visual information. 3D glasses create the illusion of three dimensions by filtering a signal containing information for both eyes. The signal, often light reflected off a movie screen or emitted from an electronic display,
11760-430: The usage of the computer is stopped. Decreasing evening screen time and setting devices to night mode will improve sleep. Several studies have shown that blue light from computers does not lead to eye diseases, including macular degeneration. The total amount of light entering the eyes can be adjusted without glasses using the screen brightness settings. Similarly, the blue light can often specifically be adjusted using
11872-595: The use of an emerald by Emperor Nero as mentioned by Pliny the Elder . The use of a convex lens to form an enlarged/magnified image was most likely described in Ptolemy 's Optics (which survives only in a poor Arabic translation). Ptolemy's description of lenses was commented upon and improved by Ibn Sahl (10th century) and most notably by Alhazen ( Book of Optics , c. 1021 ). Latin translations of Ptolemy's Optics and of Alhazen became available in Europe in
11984-569: The votes of Republicans and Northern Democrats. Thus, as Justice William Rehnquist wrote in Meritor Savings Bank v. Vinson , "The prohibition against discrimination based on sex was added to Title VII at the last minute on the floor of the House of Representatives [...] the bill quickly passed as amended, and we are left with little legislative history to guide us in interpreting the Act's prohibition against discrimination based on 'sex. ' " One of
12096-561: The wearer as a nerd , geek , elderly, or a devotee of far-right politics ; the 1993 film Falling Down in particular helped to cement an association between browlines and the " angry white male ". During the 2000s browlines were still seen as overtly conformist or "nerdy" and were still associated with 1950s culture and fashion. The influence of the television series Mad Men on the fashion world led to several eyeglass manufacturers offering browlines to meet demand for 1960s inspired frames. Major characters on several television series in
12208-407: The wearer's natural brow line. The most common means of construction is for the upper portion of the frame (the "brows" or "caps") and temples to be made of plastic, with the remainder of the frame (the bridge and eyewires, or "chassis") to be made of metal. The chassis inserts into the brows and is held in place by way of a series of screws. For a period in the 1960s, numerous models emerged in which
12320-478: Was 290–130 in the House of Representatives and 73–27 in the Senate. After the House agreed to a subsequent Senate amendment, the Civil Rights Act of 1964 was signed into law by President Johnson at the White House on July 2, 1964. In the 1883 landmark Civil Rights Cases , the United States Supreme Court had ruled that Congress did not have the power to prohibit discrimination in the private sector, thus stripping
12432-496: Was apparent that public opinion in the North favored the bill and that the petition would acquire the necessary signatures. To avert the humiliation of a successful discharge petition, Chairman Smith relented and allowed the bill to pass through the Rules Committee. Johnson, who wanted the bill passed as soon as possible, ensured that it would be quickly considered by the Senate . Normally,
12544-525: Was wary to push hard for civil rights legislation for fear of losing southern support. Moreover, according to the Miller Center , he wanted to wait until his second term to send Congress a civil rights bill. But with elevated racial tensions and a wave of African-American protests in the spring of 1963, such as the Birmingham campaign , Kennedy realized he had to act on civil rights. Kennedy first proposed
