UV protection eyeglasses should be your first choice in choosing a new pair of sunglasses. If you are a regular outdoor activities participant, extended exposure to the sun’s UV rays may lead to eye damage, including cataracts and macular degeneration. There are three categories of invisible UV rays: UVA, UVB and UVC, among which UVC is the highest in energy. UV protection sunglasses with special treatment can block these harmful rays in different degrees.

Most of the UV protection comes from the lenses of UV protection sunglasses. Special coatings on the lenses material during manufacturing are the origin of UV protection. Always select UV protection sunglasses with labels specifying UV absorption up to 400nm, which is equivalent to 100% UV absorption. Color, style and cost have no direct help in offering sun protection.

Top quality UV protection sunglasses have wraparounds on temples that provide extra protection. According to some studies, certain amount of UV rays enters around the frames to reduce the function of lenses. These wraparounds prevent UV rays from entering from the sides. So selecting UV protection sunglasses with temple wraparounds is necessary.

There are some tips you should keep in mind about UV protection sunglasses. Remember to wear your sunglasses even you are in shades since your eyes may also receive rays reflected from other objects. Fresh snow can reflect 80% UV rays so that you need to put on your UV protection sunglasses in sunny winter. Contact lenses with UV treatment cover only the part of your eyes under the lens. You need a separate pair of UV protection sunglasses to provide full UV protection.
