Sunglasses sold in the United States are regulated by the Food and Drug Administration and are required to conform to safety standards. In the basic impact test, a 1 in 2. To pass both tests, no part of the lens may touch the eye. When driving a vehicle, particularly at high speed, dazzling glare caused by a low sun, or by lights reflecting off snow, puddles, other vehicles, or even the front of the vehicle, can be lethal.
Sunglasses can protect against glare when driving. Two criteria must be met: General-purpose sunglasses may be too dark, or otherwise unsuitable for driving. The Automobile Association and the Federation of Manufacturing Opticians have produced guidance for selection of sunglasses for driving. Variable tint or photochromic lenses increase their optical density when exposed to UV light, reverting to their clear state when the UV brightness decreases.
Car windscreens filter out UV light,   slowing and limiting the reaction of the lenses and making them unsuitable for driving as they could become too dark or too light for the conditions. Some manufacturers produce special photochromic lenses that adapt to the varying light conditions when driving. Lenses of fixed tint are graded according to the optical density of the tint; in the UK sunglasses must be labelled and show the filter category number.
Yellow tinted lenses are also not recommended for night use. Polarised lenses normally have a fixed tint, and can reduce reflected glare more than non-polarised lenses of the same density, particularly on wet roads. Graduated lenses, with the bottom part lighter than the top, can make it easier to see the controls within the car. All sunglasses should be marked as meeting the standard for the region where sold. An anti-reflection coating is recommended, and a hard coating to protect the lenses from scratches.
Sunglasses with deep side arms can block side, or peripheral, vision and are not recommended for driving. Even though some of these glasses are proven good enough for driving at night, it is strongly recommended not to do so, due to the changes in a wide variety of light intensities, especially while using yellow tinted protection glasses.
The main purpose of these glasses are to protect the wearer from dust and smog particles entering into the eyes while driving at high speeds.
Many of the criteria for sunglasses worn when piloting an aircraft are similar to those for land vehicles. Protection against UV radiation is more important, as its intensity increases with altitude.
Polarised glasses are undesirable as aircraft windscreens are often polarised, intentionally or unintentionally, showing Moiré patterns on looking through the windscreen; and some LCDs used by instruments emit polarised light, and can dim or disappear when the pilot turns to look at them.
Like corrective glasses , sunglasses have to meet special requirements when worn for sports. They need shatterproof and impact-resistant lenses; a strap or other fixing is typically used to keep glasses in place during sporting activities, and they have a nose cushion.
For water sports, so-called water sunglasses also: In addition to the features for sports glasses, water sunglasses can have increased buoyancy to stop them from sinking should they come off, and they can have a vent or other method to eliminate fogging.
These sunglasses are used in water sports such as surfing , windsurfing , kiteboarding , wakeboarding , kayaking , jet skiing , bodyboarding , and water skiing. Mountain climbing or traveling across glaciers or snowfields requires above-average eye protection, because sunlight including ultraviolet radiation is more intense in higher altitudes, and snow and ice reflect additional light. Popular glasses for this use are a type called glacier glasses or glacier goggles.
They typically have very dark round lenses and leather blinders at the sides, which protect the eyes by blocking the Sun's rays around the edges of the lenses. Special shaded visors were once allowed in American football ; Jim McMahon , quarterback for the Chicago Bears and San Diego Chargers , famously used a sun visor during his professional football career due to a childhood eye injury and almost always wears dark sunglasses when not wearing a football helmet.
Darkened visors now require a doctor's prescription at most levels of the game, mainly because concussion protocol requires officials to look a player in the eye, something made difficult by tinted visors. Special protection is required for space travel because the sunlight is far more intense and harmful than on Earth, where it is always filtered through the atmosphere.
Sun protection is needed against much higher UV radiation and even against harmful infrared radiation, both within and outside the spacecraft. Within the spacecraft, astronauts wear sunglasses with darker lenses and a thin protective gold coating.
During space walks , the visor of the astronauts' helmets, which also has a thin gold coating for extra protection, functions as strong sunglasses. They must be flexible and durable, and must fit firmly in zero-gravity. Reliable fit is particularly important when wearing corrective glasses underneath tight helmets and in space suits: Frames and glasses must be designed so that small pieces of the glasses such as screws and glass particles cannot become dislodged, then float and be inhaled. The first sunglasses used in a Moon landing were the original pilot sunglasses produced by American Optical.
In they were used aboard the Eagle , the lunar landing module of Apollo 11 , the first manned mission to land on the Moon. Stephens and Charles G. Miller at the Jet Propulsion Laboratory JPL resulted in special lenses that protected against the light in space and during laser and welding work.
The lenses used colored dyes and small particles of zinc oxide , which absorbs ultraviolet light and is also used in sunscreen lotions. The research was later broadened to further terrestrial applications, e. The frame is very light at 1. Buzz Aldrin stows his sunglasses before the Moon landing. Helmet visor protecting Aldrin 's eyes on the Moon. The color of the lens can vary depending on style, fashion, and purpose, but for general use, red, grey, green, or brown are recommended to avoid or minimize color distortion , which could affect safety when, for instance, driving a car or a school bus.
With the introduction of office computing , ergonomists may recommend mildly tinted glasses for use by display operators, in order to increase contrast. While some blue blocking sunglasses see above are produced as regular sunglasses for exposure to bright sunlight, others—especially for macular degeneration patients—do not block light or other colors in order to function well in regular daylight and even dim sunlight.
Some models have polarized lenses, made of Polaroid polarized plastic sheeting, to reduce glare caused by light reflected from non-metallic surfaces such as water see Brewster's angle for how this works as well as by polarized diffuse sky radiation skylight. This can be especially useful to see beneath the surface of the water when fishing. A mirrored coating can be applied to the lens.
This mirrored coating deflects some of the light when it hits the lens so that it is not transmitted through the lens, making it useful in bright conditions; however, it does not necessarily reflect UV radiation as well.
Mirrored coatings can be made any color by the manufacturer for styling and fashion purposes. The color of the mirrored surface is irrelevant to the color of the lens. For example, a gray lens can have a blue mirror coating, and a brown lens can have a silver coating. Sunglasses of this type are sometimes called mirrorshades. A mirror coating does not get hot in sunlight and it prevents scattering of rays in the lens bulk.
Sunglass lenses are made of either glass , plastic , or SR Plastic lenses are typically made from acrylic , polycarbonate , CR or polyurethane. Glass lenses have the best optical clarity and scratch resistance, but are heavier than plastic lenses.
They can also shatter or break on impact. Plastic lenses are lighter and shatter-resistant, but are more prone to scratching. Polycarbonate plastic lenses are the lightest, and are also almost shatterproof, making them good for impact protection.
CR is the most common plastic lens, due to low weight, high scratch resistance, and low transparency for ultraviolet and infrared radiation. SR is a proprietary material that was introduced by Kaenon Polarized in Kaenon's lens formulation was the first non-polycarbonate material to pass the high-mass impact ANSI Z.
Additionally, it was the first to combine this passing score with the highest marks for lens clarity. Jerry Garcia's sunglasses had a polykrypton-C type of lens which was 'cutting edge' in Any of the above features, color, polarization, gradation, mirroring, and materials, can be combined into the lens for a pair of sunglasses.
Gradient glasses are darker at the top of the lens where the sky is viewed and transparent at the bottom. Corrective lenses or glasses can be manufactured with either tinting or darkened to serve as sunglasses. An alternative is to use the corrective glasses with a secondary lenses such as oversize sunglasses that fit over the regular glasses, clip-on lens that are placed in front of the glasses, and flip-up glasses which feature a dark lens that can be flipped up when not in use see below.
Photochromic lenses gradually darken when exposed to ultraviolet light. Frames are generally made of plastic, nylon , a metal or a metal alloy. Nylon frames are usually used in sports because they are lightweight and flexible.
They are able to bend slightly and return to their original shape instead of breaking when pressure is applied to them. This flex can also help the glasses grip better on the wearer's face. Metal frames are usually more rigid than nylon frames, thus they can be more easily damaged when the wearer participates in sport activities, but this is not to say that they cannot be used for such activities.
Because metal frames are more rigid, some models have spring loaded hinges to help them grip the wearer's face better. The end of the resting hook and the bridge over the nose can be textured or have rubber or plastic material to improve hold. The ends of the resting hook are usually curved so that they wrap around the ear; however, some models have straight resting hooks. Oakley , for example, has straight resting hooks on all their glasses, preferring to call them "earstems".
In recent years, manufacturers have started to use various types of woods to make frames for sunglasses. Materials such as bamboo , ebony , rosewood , pear wood, walnut and zebrawood , are used making them non-toxic and nearly allergy free. The construction of a wooden frame involves laser-cutting from planks of wood. Already cut and ground to a uniform size, a buffing wheel is used to sand and buff every piece separately before they are assembled.
The laser-cutouts of wood are then glued together by hand mostly , layer on layer, to produce wooden frames. Some brands have experimented with recycled wood from objects like skateboards , whiskey barrels and baseball bats. Shwood , for example have experimented with these materials, they have even used recycled newspaper to manufacture frames. Their final look can vary according to the color, type and finishing. With wooden sunglasses, various shades of brown, beige, burgundy or black are most common.
Wooden sunglasses come in various designs and shapes. However, these sunglasses are usually more expensive than the conventional plastic, acetate or metal frames and require more care. Frames can be made to hold the lenses in several different ways. There are three common styles: Full frame glasses have the frame go all around the lenses. Half frames go around only half the lens; typically the frames attach to the top of the lenses and on the side near the top. Frameless glasses have no frame around the lenses and the ear stems are attached directly to the lenses.
There are two styles of frameless glasses: Some sports-optimized sunglasses have interchangeable lens options. Lenses can be easily removed and swapped for a different lens, usually of a different color.
The purpose is to allow the wearer to easily change lenses when light conditions or activities change. The reasons are that the cost of a set of lenses is less than the cost of a separate pair of glasses, and carrying extra lenses is less bulky than carrying multiple pairs of glasses.
It also allows easy replacement of a set of lenses if they are damaged. The most common type of sunglasses with interchangeable lenses has a single lens or shield that covers both eyes. Styles that use two lenses also exist, but are less common.
Nose bridges provide support between the lens and the face. They also prevent pressure marks caused by the weight of the lens or frame on the cheeks. People with large noses may need a low nose bridge on their sunglasses. People with medium noses may need a low or medium nose bridge.
People with small noses may need sunglasses with high nose bridges to allow clearance. The following types are not all mutually exclusive; glasses may be in Aviator style with mirrored lenses, for example. Aviator sunglasses feature oversize teardrop-shaped lenses and a thin metal frame. As a fashion statement, aviator sunglasses are often made in mirrored, colored, and wrap-around styles. The model first gained popularity in the s when Douglas MacArthur was seen sporting a pair at the Pacific Theatre.
However, it was in the late s when the frames became widely used with the rise of the hippie counterculture, which preferred large metallic sunglasses. The brand became an icon of the s, worn by Paul McCartney and Freddie Mercury among others, and was also used as prescription eyeglasses. Aviators' association with disco culture led to a decline in their popularity by Aviators became popular again around , as the hippie movement experienced a brief revival, and was prominently featured in the MTV show Jackass.
Based on the eyeglass design of the same name, browline glasses have hard plastic or horn-rimmed arms and upper portions joined to a wire lower frame. A traditional, conservative style based on midth century design, browlines were adapted into sunglasses form in the s and rapidly became one of the most popular styles; it has ebbed and sprung in popularity in the decades that have followed.
Oversized sunglasses, which were fashionable in the s, are now often used for humorous purposes. They usually come in bright colors with colored lenses and can be purchased cheaply. The singer Elton John sometimes wore oversized sunglasses on stage in the mids as part of his Captain Fantastic act.
Since the late s, moderately oversized sunglasses have become a fashion trend. There are many variations, such as the "Onassis", discussed below, and Dior white sunglasses. Onassis glasses or "Jackie O's" are very large sunglasses worn by women. This style of sunglasses is said to mimic the kind most famously worn by Jacqueline Kennedy Onassis in the s. The glasses continue to be popular with women, and celebrities may use them, ostensibly to hide from paparazzi.
Oversized sunglasses, because of their larger frames and lenses, are useful for individuals who are trying to minimize the apparent size or arch of their nose. Oversized sunglasses also offer more protection from sunburn due to the larger areas of skin they cover, although sunblock should still be used. Shutter shades were invented in the late s, became a fad in the early s and have experienced a revival in the early-to-mid s.
Instead of tinted lenses, they decrease sun exposure by means of a set of parallel, horizontal shutters like a small window shutter. Analogous to Inuit goggles see above , the principle is not to filter light, but to decrease the amount of sun rays falling into the wearer's eyes.
To provide UV protection, shutter shades sometimes use lenses in addition to the shutters; if not, they provide very insufficient protection against ultraviolet radiation and blue light.
The original teashade design was made up of medium-sized, perfectly round lenses, supported by pads on the bridge of the nose and a thin wire frame. When teashades became popular in the late s, they were often elaborated: Lenses were elaborately colored, mirrored, and produced in excessively large sizes, and with the wire earpieces exaggerated.
A uniquely colored or darkened glass lens was usually preferred. Modern versions tend to have plastic lenses, as do many other sunglasses.
Teashades are hard to find in shops today; however, they can still be found at many costume Web sites and in some countries. The term has now fallen into disuse, although references can still be found in literature of the time. The Ray-Ban Wayfarer is a mostly plastic-framed design for sunglasses produced by the Ray-Ban company. Introduced in , the trapezoidal lenses are wider at the top than the bottom inspired by the Browline eyeglasses popular at the time , and were famously worn by James Dean , Roy Orbison , Elvis Presley , Bob Marley , The Beatles and other actors and singers.
The original frames were black; frames in many different colors were later introduced. There is often a silver piece on the corners as well.
