What are polarized lenses and what do they do?
Contray to what you might think, light do not travel in a straight line: it bounces back and forth from one reflective surface to another which causes glare. Glare is especially noticable from glass, water, metal, and even white sand on the beach. So how can you protect yourself from a lifetime of squinting outside? You can protect your eyes from harful glare by wearing polarized lenses.
When you’re wearing polarized lens, things which you couldn't see because of the glare before become clear as day while removing the glare and increase your visual contrast. Suddenly instead of being blinded by the glaring light you now can see through it.
Fisherman can see fish under the water that were previously invisible, swimmers and water skiers can see rocks and snags that were hidden before. This is not to claim that polarized sunglasses allow you to see everything that may have been hidden before, but cutting that mirror like glare certainly does make a big difference.
For most sports and outdoor activities, polarized sunglasses offer great advantages.
Whether you spend your time water skiing or boating, golfing or mountain biking, driving or jogging, polarized sunglasses may be the right choice to help you enjoy your life outdoors.

Polarized lenses permit only vertical light rays to pass through them, not horizontal, and thus they greatly reduce glare up to 99.9% providing clear, glare-free vision. Polarized lenses contain vertical stripes which allow only vertically polarized light to enter your eyes. to hlep you visualize this concept, think of the polarized film as window blinds with slats. Light travels in waves. As the waves come to the slats, any waves that are not lined up with the openings in the slats are blocked out.
