Further Function of sunglasses

While non-tinted glasses are very rarely worn without the practical purpose of correcting eyesight or protecting one's eyes, sunglasses have become popular for several further reasons, and are sometimes worn even indoors or at night.

Celebrity have their own reason why they wearing sunglasses. MJ with small Aviator Ray ban

Sunglasses can be worn to hide one's eyes. They can make eye contact impossible, which can be intimidating to those not wearing sunglasses; the avoided eye contact can also demonstrate the wearer's detachment,[citation needed] which is considered desirable ("cool") in some circles. Eye contact can be avoided even more effectively by using mirrored sunglasses. Sunglasses can also be used to hide emotions; this can range from hiding blinking to hiding weeping and its resulting red eyes. In all cases, hiding one's eyes has implications for nonverbal communication.

Fashion trends can be another reason for wearing sunglasses, particularly designer sunglasses. Sunglasses of particular shapes may be in vogue as a fashion accessory. Fashion trends can also draw on the "cool" image of sunglasses.

People may also wear sunglasses to hide an abnormal appearance of their eyes. This can be true for people with severe visual impairment, such as the blind, who may wear sunglasses to avoid making others uncomfortable. The assumption is that it may be more comfortable for another person not to see the hidden eyes rather than see abnormal eyes or eyes which seem to look in the wrong direction. People may also wear sunglasses to hide dilated or contracted pupils, bloodshot eyes due to drug use, recent physical abuse (such as a black eye), exophthalmos (bulging eyes), a cataract, or eyes which jerk uncontrollably (nystagmus).

How do i check my Ray ban is original

1) A genuine ray ban has near the arm of the left lens two letters: RB! If it isn’t so they are fake. If they have the letters Bl they are not Luxottica (actual Ray ban producer) but Bausch & Lomb that produced Ray ban ten years ago (so it is an old sunglass).

2) Right lens has the Rayban sign in full.

3) Under the nose bridge is written the sunglass size.

4) All "glasant" models (without frame) has almost invisible lens support (not micro-bolt).

5) Fake models give an aberrance feeling, like a lack of depth while looking the ground (due to lens bad quality)

6) On left arm there is the product and color code. Fake models generally has dummy codes.

7) A too low price denotes something wrong…you will never save more than 35% in comparison with the shop price.

Visual clarity and comfort

Sunglasses can improve visual comfort and visual clarity by protecting the eye from glare.

Various types of disposable sunglasses are dispensed to patients after receiving mydriatic eye drops during eye examinations.

The lenses of polarized sunglasses reduce glare reflected at some angles off shiny non-metallic surfaces such as water. They are popular among fishermen because they allow wearers to see into water when normally only glare would be seen.

Function

Sunglasses offer protection against excessive exposure to light, including its visible and invisible components.

The most widespread protection is against ultraviolet radiation, which can cause short-term and long-term ocular problems such as photokeratitis, snow blindness, cataracts, pterygium, and various forms of eye cancer. Medical experts advise the public on the importance of wearing sunglasses to protect the eyes from UV for adequate protection, experts recommend sunglasses that reflect or filter out 99-100 % of UVA and UVB light, with wavelengths up to 400 nm. Sunglasses which meet this requirement are often labeled as "UV 400." This is slightly more protection than the widely used standard of the European Union, which requires that 95 % of the radiation up to only 380 nm must be reflected or filtered out. Sunglasses are not sufficient to protect the eyes against permanent harm from looking directly at the Sun, even during a solar eclipse.

More recently, high-energy visible light (HEV) has been implicated as a cause of age-related macular degeneration before, debates had already existed as to whether "blue blocking" or amber tinted lenses may have a protective effect. Some manufacturers already design to block blue light to develop norms for blue blocking, leading to a recommended minimum of 95% of the blue light. Sunglasses important for children, as their ocular lenses are thought to transmit far more HEV light than adults (lenses "yellow" with age).

There has been some speculation that sunglasses actually promote skin cancer.This is due to the eyes being tricked into producing less melanocyte-stimulating hormone in the body.

Assessing the protection of sunglasses

The only way to assess the protection of sunglasses is to have the lenses measured, either by the manufacturer or by a properly equipped optician. Several standards for sunglasses allow a general classification of the UV protection (but not the blue light protection), and manufacturers often indicate simply that the sunglasses meet the requirements of a specific standard rather than publish the exact figures.

The only "visible" quality test for sunglasses is their fit. The lenses should fit close enough to the face that only very little "stray light" can reach the eye from their sides, or from above or below, but not so close that the eyelashes smear the lenses. To protect against "stray light" from the sides, the lenses should fit close enough to the temples and/or merge into broad temple arms or leather blinders.

It is not possible to "see" the protection that sunglasses offer. Dark lenses do not automatically filter out more harmful UV radiation and blue light as compared to light lenses. Inadequate dark lenses are even more harmful than inadequate light lenses (or wearing no sunglasses at all) because they provoke the pupil to open wider. As result, more unfiltered radiation enters the eye. Depending on the manufacturing technology, sufficiently protective lenses can block much or little light, resulting in dark or light lenses. The lens color is not a guarantee either. Lenses of various colors can offer sufficient (or insufficient) UV protection. Regarding blue light, the color gives at least a first indication: Blue blocking lenses are commonly yellow or brown whereas blue or gray lenses cannot offer the necessary blue light protection. However, not every yellow or brown lens blocks sufficient blue light. In rare cases, lenses can filter out too much blue light (i.e., 100 %), which affects color vision and can be dangerous in traffic when colored signals are not properly recognized.

High prices cannot guarantee sufficient protection as no correlation between high prices and increased UV protection has been demonstrated. A 1995 study reported that "Expensive brands and polarizing sunglasses do not guarantee optimal UVA protection." The Australian Competition and Consumer Commission has also reported that "consumers cannot rely on price as an indicator of quality". One survey even found that a $6.95 pair of generic glasses offered slightly better protection than did expensive shades.

Modern developments

Now so many design of sunglasses on market with modern and rare design

In the early 1900s, the use of sunglasses started to become more widespread, especially among stars of silent movies. It is commonly believed that this was to avoid recognition by fans, but the real reason was they often had perennially red eyes from the powerful arc lamps that were needed due to the extremely slow speed film stocks used. The stereotype persisted long after improvements in film quality and the introduction of ultraviolet filters had eliminated this problem. Inexpensive mass-produced sunglasses were introduced to America by Sam Foster in 1929. Foster found a ready market on the beaches of Atlantic City, New Jersey, where he began selling sunglasses under the name Foster Grant from a Woolworth on the Boardwalk.

Polarized sunglasses first became available in 1936, when Edwin H. Land began experimenting with making lenses with his patented Polaroid filter.

A long time history of sunglasses

In prehistoric and historic time, Inuit peoples wore flattened walrus ivory "glasses," looking through narrow slits to block harmful reflected rays of the sun.

inut snow goggle purpose to reduce exposure of sun ray not sun intensity

It is said that the Roman emperor Nero liked to watch gladiator fights with emeralds. These, however, appear to have worked rather like mirrors. Flat panes of smoky quartz which offered no corrective powers but did protect the eyes from glare were used in China in the 12th century or possibly earlier. Contemporary documents describe the use of such crystals by judges in Chinese courts to conceal their facial expressions while questioning witnesses.

James Ayscough began experimenting with tinted lenses in spectacles in the mid-18th century, around 1752. These were not "sunglasses" as such; Ayscough believed blue- or green-tinted glass could correct for specific vision impairments. Protection from the Sun's rays was not a concern for him.

Yellow/amber and brown-tinted spectacles were also a commonly-prescribed item for people with syphilis in the 19th and early 20th centuries because sensitivity to light was one of the symptoms of the disease.

Introduction

Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. In the early 20th century they were also known as sun cheaters (cheaters being an American slang term for glasses).

Many people find direct sunlight too bright for comfort. During outdoor activities, the human eye can receive more light than usual. Health care professionals recommend eye protection whenever outside to protect the eyes from ultraviolet radiation (UV) and blue light, which can cause several serious eye problems. Sunglasses have long been associated with celebrities and film actors primarily from a desire to mask their identity. Since the 1940s sunglasses have been popular as a fashion accessory, especially on the beach.

Luxottica target 27% rise in 2010 net income

Luxottica Group SpA, owner of the Ray-Ban and Oakley sunglasses brands, aims to raise net income 27 percent this year after demand in emerging markets and renewed interest in luxury eyewear boosted quarterly sales.

Net income may rise to 400 million euros ($561 million) from 315 million euros in 2009, Milan-based Luxottica said in a statement after trading today. That’s in line with a 400.5 million-euro average estimate of 12 analysts compiled by Bloomberg.

Luxottica, the world’s largest maker of eyewear, returned to earnings growth in the final quarter of 2009 after consumers deferred purchases for almost two years during the recession. The company is “optimistic” for the rest of 2010, Chief Executive Officer Andrea Guerra said in the statement.

Third-quarter net income advanced 35 percent to 101.9 million euros, compared with a 98 million-euro average estimate of 12 analysts surveyed by Bloomberg. Sales in the three months ended Sept. 30 rose 20 percent to 1.46 billion euros.

The Italian company, which makes eyewear under license for Chanel and Prada, said sales in “key emerging markets” rose 26 percent in the quarter, while European revenue advanced 13 percent and U.S.-dollar sales in North America rose 8.5 percent.

Wholesale revenue for luxury brands advanced 18 percent, the second consecutive quarterly gain, Luxottica said. Wholesale revenue in emerging markets, which account for about 13 percent of total wholesale sales for the company, rose more than 20 percent for the fourth straight quarter, with about a 40 percent increase in India and South Korea.

Luxottica, which owns the LensCrafters and Sunglass Hut store brands, said retail-division revenue rose to 946.5 million euros in the third quarter from 793.8 million euros last year.

3D glasses eyewear will be on market

MILAN — Italian eyewear giant Luxottica said on Wednesday it would launch the world's first range of glasses for watching 3D films with prescription lenses through its US brand Oakley later this year.

Oakley "has achieved unparalleled visual clarity while extending the wearer's peripheral viewing angle and providing a truer alignment of 3D images," Luxottica said in a statement.

Luxottica said it has been using the workshops of US industry giant DreamWorks Animation for testing.

The company said "premium editions in the new line will be the first 3D eyewear on Earth with optically correct lenses".

The first pairs of 3D glasses will be available in the United States later this year and will be launched in the rest of the world in 2011.

"We are very proud of this technological breakthrough," Andrea Guerra, chief executive of Luxottica, was quoted as saying.

The market for 3D cinema and television viewing is currently booming.

Fuji Chimera, a Japanese economic research centre, said in a study published in July that the number of televisions on the market equipped with 3D technology would constitute around half of the world total by 2015.

Coach team with Luxottica on eyewear

ROME—Italian eyewear maker Luxottica Group SpA and U.S. leather accessories brand Coach Inc. Tuesday announced an eyewear partnership expected to add more than $100 million a year in sales.

The move gives Luxottica, the world's largest eyewear maker, further traction in North America and Asia, where Coach is expanding. It also adds a large middle-market label to a portfolio full of high-end brands such as Bulgari SpA and Prada SpA.

"We think there's a lot of opportunity for somewhat accessible luxury today in the global market," said Antonio Miyakawa, executive vice president marketing, creative direction and product at Luxottica.

The multiyear deal, which begins in 2012, signals the end of Coach's existing contract with U.S. producer Marchon. Luxottica offers its own vast retail channel.

It's a good fit as Coach gains access to a global platform to accompany the rollout of its brand, while Luxottica gets a "great add-on to its otherwise very European luxury oriented portfolio," allowing it to avoid the risk of cannibalization, said Erwan Rambourg, an analyst for HSBC in London. He expects Coach to quickly establish itself as one of Luxottica's top five brands, alongside Prada, Chanel and D&G.

Mr. Miyakawa said Luxottica admires Coach's growth in the U.S. and expansion plans in Asia and expected Luxottica to be able to help it grow in Europe, too.

"We're very excited about this partnership, which will combine Coach's distinct design aesthetic with Luxottica's excellent product quality and craftsmanship," Coach Chairman and Chief Executive Lew Frankfort said in a statement.
