Due possibly to changes in the ozone layer, protection from Ultra Violet (UV) radiation is becoming a serious consideration. Wearing good quality sunglasses is becoming almost mandatory, especially during the summer and winter months. They are no longer just an extra accoutrement to help you look cool on the beach or on the ski slopes.
From the polished lens made from emeralds worn by Nero to watch the Gladiator contests, sunglasses have evolved through the last two thousand years to the modern choices we have today. Sunglasses as we know them actually were developed by James Ayscough in the 1750's when he ground the first blue and green corrective lenses for correcting optical impairments.
By the 20th Century, sunglasses were used to protect the eyes from the sun. In 1929 Sam Foster's "Foster Grants" were the first mass-produced sunglasses and they began the trend of sunglasses for fashion.
In the 1930's the Army Air Corps asked Bausch & Lomb to develop sunglasses that would efficiently reduce high-altitude sun glare for pilots and they came up with dark green tinted sunglasses that absorbed light through the yellow spectrum.
The Polaroid filter was invented by Edward H. Land and first used by him in making sunglasses by 1936. The next step in the evolution of sunglasses came in 1937 when Ray Ban developed the anti-glare lenses using polarization. These became known as Aviator Glasses. The style was created to give more protection to pilots' eyes from sunlight reflecting off their control panels.
In the 1970's movie stars and fashionistas made a big impact on the marketing of sunglasses by adding their endorsements. Now everyone had to have a pair of the latest hot craze. Now in 2009 not much has changed. Movie stars, rock singers, everyone who is anyone, hide behind their oversized sunglasses making a fashion statement and at the same time protecting their eyes from the harmful Ultra Violet radiation.
UV rays can cause serious damage to the corneas, and a good pair of sunglasses will shield 100% of these rays. A protective coating on the outside of sunglasses acts as a kind of filter. While it allows light through, it helps to filter out the radioactive light waves that can lead to so many dangers to your eyes.
In addition to filtering out UV rays, modern sunglasses are usually tinted to control the amount of light your eyes will be exposed to. Different shades of tinting will protect in their own ways. Lenses tinted in gray and almost black offer the greatest amount of protection from intense lights while avoiding distortion of most colors that the human eye can detect.
Good quality sunglasses afford us protection from glare. Light reflecting off water surfaces can produce glare, so can white snow or any number of other shiny surfaces. The glare can block out other objects like an oncoming vehicle Be sure your new sunglasses are polarized to eliminate glare.
The tint you choose for your sunglasses is important as some tints can actually cause blurred vision, while others can enhance the contrast between colors. First decide under what conditions and where you are going to be wearing your new sunglasses, then choose the most overall beneficial tinting.
Blue light is a color of light that can cause burred perception, so sunglasses that are yellow, gold, amber and brown can be chosen to counteract blue light. Yellow tinted lenses, while making the rest of the world look a different color, will enable you to see the most clearly through them.
Green tinted sunglasses have long been the most popular shades as they both filter out some blue light and also reduce the effects of glare. They offer the highest contrast and provide the best visual enhancement of any of the tints normally available. If you are a water skier or a duck hunter, you might prefer rose colored or purple tinted sunglasses as they give the best contrast against green or blue backgrounds.
Before selecting your next pair of sunglasses, decide where you are going to wear them most often and under what conditions. Then go for the best quality you can afford, stressing that your new sunglasses will provide UV radiation protection, have anti-glare properties, together with the optimal color tint that best suits your lifestyle.
