Five hundred years ago, a Spanish missionary mentioned in his book that they bad brought eyeglasses from China, however, they didn’t have any evidence to prove what he said. Another story is about the wind eyewear used by Eskimo in five hundred years ago. As a matter of fact, this wind eyewear is just a long board with two cracks, so it is obvious that it couldn’t be regarded as sunglasses. But the firm truth is that the modern rx sunglasses are invented by Europeans.

In the beginning of the twenty century, the wind eyewear only for driving has become a rich and fashionable symbol. Wind eyewear is mainly made up of glasses, but the price is rather high. In the 1930’s, Germen and Americans invented the polystyrene plastics one after the other. This material is just as transparent as the glass and quite firm.

John Lennon always wore the small round eyeglasses with thin metal frames. Therefore, such eyeglasses and the sunglasses in the same style had affected the trend of sunglasses’ appearance at that time. They tended to be more and more round and the design of them also became braver and braver.

In the seventies, the appearance of the sunglasses was gradually turning to the development of having angles. Plastics sunglasses with the smooth brims and the round angles were favored by more and more people. The lenses of the sunglasses had appeared to be colorful in a progressive point. The famous fashion designer Yves Saint Laurent had such kind of sunglasses at his years.

In the eighties, the square looking with obvious angles at this time had already reached its peak. Chanel’s designer Karl Lagerfeld who had taken over her is one of the representatives. He wears a pair of slight square sunglasses all year round. His very image has already been applied into the design of the brand—Karl Lagerfeld Teddy Bear and Karl Lagerfeld Bag are two best examples.

Why Sunglasses are Effective

All your life you have heard about the importance of sunglasses. You are probably aware that they are used to protect your eyes, blocking them from sunlight and preserving your vision.

But do you know how sunglasses actually do all that? Apart from complementing your look, they work in four different ways. You should learn what these are and make sure that your sunglasses are actually doing the work they are meant to.

Ultraviolet rays are present in sunlight and these can cause damage the corneas. Sunglasses help give your eyes protection from the dangerous UV rays, and good ones give your eyes 100% protection. A coating is put outside the lenses of the sunglasses which acts as a UV filter. It allows light to pass through, so you can see, but blocks out the UV light which can harm your eyes.

The most common reason people wear sunglasses is to get protection from the glare of sunlight. Powerful sunlight can make you close your eyes or narrow them, thus causing a squint. This is a natural reaction which protects the corneas. It is not just bright sunlight which can cause damage, but also glare from the snow, because snow reflects the sunlight highly intensified and magnified, so it can be even more dangerous.

Sunglasses are tinted according to your requirements, based on how much light protection is needed. Just as there are different types of light, the various shades of the lenses of sunglasses also protect your eyes in their differing ways. Among the good lens colors are gray and almost black which give the most protection from powerful light, at the same time not distorting colors.

Of utmost importance is the fact the sunglasses safeguard your eyes from glare. The sunlight reflects off water and shiny surfaces which amplify the light and cause glare, which can be blinding if you don’t wear sunglasses and can even cause accidents. Good sunglasses shield eyes from this kind of glare.

Just as sound waves vibrate so do light waves and when a group comes together, the result is a glare. If you get blinded by glare off water or glass (like the windshield of a car), you see a combination of light waves. There are polarization filters which are used in the lenses of sunglasses which realign the waves and thus get rid of the glare.

Sunglasses can eradicate particular light frequencies which can cause vision to blur or change colors. Therefore selecting the correct color of the lenses of the sunglasses helps them protect your eyes in different conditions.

If you want to block out blue light, then you ought to be wearing sunglasses whose lenses are yellow, gold, amber or brown. Blue light is the major color which causes blurred vision. Even though yellow lenses have a tendency to distort other colors, their benefits far outweigh their disadvantages.

Similar to yellow lenses, green lenses also filter blue light and help in protecting eyes from glare. Their higher contrast features and the fact that they offer great visual sharpness also make them extremely popular. Other colored lenses are rose and purple, and they give the best contrast and protection in the green or blue background. That is why they are good for hunting and water skiing.

The History of Ray Ban Sunglasses

If you have ever seen Tom Cruise in “Risky Business”, you will remember two things. The first being the most famous scene from that movie, the one where he comes sliding into the living room dancing in his underwear, and the second, how good he looked in those sunglasses.

Cruise sported Ray Ban sunglasses in this movie and they became as big a hit as the movie itself. By the time this movie was made in 1983 however, Ray Ban had already been making popular sunglasses for 46 years.

The optical firm Bausch and Lomb launched the first Ray Ban sunglasses in 1936, which were anti-glare aviator sunglasses. They were the first to use polarized technology, which was developed by Edwin H. Land, the founder of the Polaroid Corporation.

These dark glasses had large lenses, about two or three times the size of the eye socket, in the shape of an oblique teardrop. Instead of being flat, these glasses were slightly convex. The goal of these large, curved glasses was to protect the eyes from every angle for optimal protection from the sun.

In the 1940’s, Ray Ban was hired by the US Air Force to develop these glasses even further for use by air force pilots. The Aviator glasses soon became popular with the other branches of the US military as well and when General Douglas MacArthur was photographed landing on a beach in the Philippines during World War II, he was wearing a pair of Ray Bans.

Ray Ban has relied on photographs of celebrities to promote their eyewear throughout the years. The Blues Brothers, Miami Vice’s Don Johnson, Michael Jackson, and Madonna are just a few of the people who join Tom Cruise as Ray Ban wearers and promoters.

Ray Ban Aviators have remained in style for decades but this company also moved with the times in terms of its other models. There were bright, colorful frames to reflect the style of the 60’s, big flashy shades in the 70’s, and sportier designs of the 80’s.

From the beginning, Ray Ban sunglasses have been at the forefront of eye protection technology. These glasses stay in style not only because of their celebrity appeal but also because they are well made and practical.

History of Eyeglasses to Sunglasses

Somewhere around 1200-1300A.D. a well known philosopher and scientist by the name of Roger Bacon made his mark in history when he recorded the first known use of lenses.

While teaching at Oxford he worked hard on research and experiments. Later Pope Clement IV convinced him to write books about his theories and experiments. Pope Nicholas IV had him imprisoned because he didn?? agree with Bacon. Before his life ended Bacon made many discoveries and wrote many more books.

The Romans have been said to have used water filled glasses to read with and while watching those who were less fortunate to be in an arena they used some stones of various colors to shield their eyes. Romans were known for wanting the best out of life so its no surprise that they used stones like quartz to enhance vision or reduce glare

Salvino D’Armate invented the first known official pair of eyeglasses around 1284 in Italy. Alessandro Spina has been also said to be the first. Italians introduced eyeglasses to the Chinese and folk loar says Chinese judges used green eyeglasses to hide their expressions while passing judgment.

Eyeglass designer and maker of scientific devices James Ayscough developed a set of eyeglasses that used clear or green lenses in 1752. Ayscough thought that the green lenses helped vision some and relieved some eye fatigue. He was an apprentice to James Mann. The two became partners in developing microscopes and the publishing of articles.

By the early part of the 1900’s well known figures helped inspire the production and use of sunglasses. In 1929 Sam Foster started selling his version of sunglasses called Foster Grants.

The polarization of sunglasses was accomplished by Edwin H. Land. Land invented polarized material that he used on sunglasses. George Wheelright and Land became partners and started in 1937 the Polaroid Corporation. Lands polarized sheeting material was use in sunglasses, 3-D movies and for military use. Later the polaroid camera came along another of Lands products.

By the 1950’s sunglasses were exploding on the scene with great stride and to present time sunglasses have become more popular than ever.

Manufacturers now have improved sunglasses greatly not only providing great styles, but now sunglasses protect against UVA & UVB Lights Rays and from eye problems such as macular degeneration. So make sure you protect your eyes and your childrens.

History of Sunglasses

Precursors

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. 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 of his.

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

Modern developments

In the early 1900s, the use of sunglasses started to become more widespread, especially among the pioneering 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 sore eyes from the powerful arc lights 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.

Sunglasses first became polarized in 1936, when Edwin H. Land began experimenting with making lenses with his patented Polaroid filter.

In 2004, Oakley developed the THUMP, sunglasses with built-in digital audio player. This design has been copied by a number of smaller companies.

Introduce oIntroduce of Lens Types of Sunglasses

There are about four common types of lens including polycarbonate, glass, acrylic and unless started otherwisePolycarbonate: The most common lens material used in sunglasses today.

Offers the highest impact resistance of any lens material.

Addition, polycarbonate lenses are 10x more impact resistant than conventional plastic or glass lenses.

Polycarbonate can be mixed with many tints to produce lens shades. After injection, the material is placed in a centrifical force mechanism to adjust its optical correctness and curvature base.

Glass: Has the best optical quality and higest scratch resistance of all lens materials, although its weight should be considered. Also the material of choice for perscription sunglass lenses.

Acrylic: Unlike polycarbonate or glass, acrylic is not naturally UV protective. As a result, UV coatings are applied during the manufacturing process.

Unless stated otherwise, all sunglasses featured at The Sunglass Man feature polycarbonate lenses.

2.Narrow Face

We defined it by a set of chin and cheek are of nearly the same width while facial length is far greater than the width.With this face shape frames should cover as much of the center of the face as possible in order to minimize the length.

We defined it by a broad forehead while narrow mouth and chin. Do avoid large frames, heavy nose bridges, bold colors and square shapes.

The best example may be a wrap frame. Many manufactures including Nike and Carrera make them right now. The only disadvantage is that it is difficult to put a prescription in them due to the extreme wrap of the frame. It’s too flat for most prescription lenses to successfully stay in a frame to give you clear vision. Right now,new trends in frames include a lot of embellishments including rhinestones and inlays.

It’s examples are the Christian Dior Monday and the Via Spiga 402-s. Another new strongley trend is the drilled mounted shields. Ralph Lauren, Giorgio Armani and Kate Spade all provide excellent choices for you both for non prescription and prescription.

It also comes in all types of prescriptions including sv, bifocals, trifocals and popular Varilux Progressives.You wouldn’t need to matter the it’s thickness either because they may come in all types of materials including polycarbonate,hi index,plastic and so on.

Other Choices

Other choices there are too. There are photo chromic lenses. These lenses change color with the uv rays from the sun. They are 100% uv protective, come in gray and brown.When an Anti-reflective coating is added, the lenses are perfectly clear indoors and sunglass darkness in direct sunlight.. There is one disadventage also, the lenses do not change color in a car. Because the ultraviolet rays needed to change the lenses will be absorbed by windshields of cars

If you do not care about what is talked above.You could also just choose the traditional sunglasses.With a dark lens in either gray (the number one choice), brown, or any other fashion tint under the sun.The trendiest colors right now are cooper, coral, mint green and aqua. Keep in mind these are not true sun lenses.

If they are tinted to dark, they can effect driving and effect contrast. Standard tint should allow between 8% and 30% transmission of light to the eye.You must remember that each pair of sunglasses should be 100% UVA and UVB protective.

And you shuoldn’t go by the stickers or designer name.Do make a cheak of them and have your taste!
