Virtually all prescription polarizing lenses, glass, plastic, and polycarbonate protect the eye from damage caused by long term exposure to ultraviolet light. This is a big benefit, since the same surfaces that reflect light in a polarized manner also reflect a high amount of UV light. Listed below are approximate percentages of UV absorbing polarized lenses.

More Advantages of Polarized Lenses:

Driving fatigue is reduced--Much of the light reflected from large pavement is polarized, so people who do a lot of daytime driving will benefit from polarizing lenses.

Fishing and other outdoor water activities enhanced--Light reflected from the surface of the water prevent the viewer from seeing below the surface. Polarized lenses not only eliminate this glare, but enables the wearer to see below the surface as well. Also, sand at the beach is a source of this same glare.

Snow is very reflective--People who are out working or driving in the snow will see the benefit from using polarized lenses.

Everyone can benefit from polarized lenses--So many cases of glare occur during the day, (bumpers on cars, windows on buildings) a good demonstration can show how everyone can benefit. When glare disappears color returns.

Did You Know...?
In sunlight there are two bands of radiation that can affect your eyes: UVA can cause sun tanning, wrinkles, and sagging skin. It may also be harmful to the cornea and the retina of the eyes. UVB is higher-energy radiation.... and more dangerous. This band of radiation, also known as the sunburn rays, can cause photokeratitis (snow blindness is an example of photokeratitis).
