Everyone wants to look good in their sunglasses but what really counts is the protection they provide from the harmful rays of the sun.
Sunglasses were originally created for Navy pilots to use during high altitude flights. Today’s sunglasses come in hundreds of colors and styles to please any taste but their underlying purpose remains the same.
The goal of using sunglasses is to provide 100 percent protection from damaging ultraviolet rays. With enough exposure, ultraviolet rays can damage the cornea. Early sunglasses were developed using glass. The glass was ground and treated to protect against UV rays. An optical grinder was used to create lenses free from distortion.
When a lens is distorted it can cause the wearer to have headaches and dizziness, so buying sunglasses with optically ground glass is important. It will also protect your vision.
Glass provides a natural protection against UV rays, so it will provide the wearer with the proper amount of protection from the sun.
It’s also necessary to consider the color of the lens. They should be dark enough to allow about 15 percent of natural light to penetrate. This will give you sufficient protection from the negative effects of the sun’s rays.
In tests, scientists learned that the glare pilots experienced flying in high altitudes, was best reduced by glasses that blocked out 85 percent of sunlight. When selecting sunglasses for yourself, remember to that darker is better for blocking out UV rays.
There are a lot of things to consider when choosing the right pair of sunglasses.
If you’re looking for the best sunglasses with optimum UV protection, find a pair that uses optically ground glass and a tint that only allows 15 percent penetration of the sun’s rays. Beyond that, choose a style that is comfortable and flattering.
