Outdoor enthusiasts are especially keen on these sunglasses, and this includes skiers, snowboarders, bikers, joggers, even just people who want to hang outside in the sun and have protection for their eyes.
How They Work
The way that polarized sunglasses is really quite simple. In the simplest terms these glasses help to reduce the glare of light, from the sun more than anything. The sun can shine off of snow, flat roads and smooth water, for example, and this can result in being very dangerous to those who need to be able to see straight ahead of them.
Polarized lenses allow only light in one pane to pass through the lens, and therefore much of the glare from the sun is eliminated. Regular sunglasses, although they do help protect the eyes from the harmful UV rays of the sun, they are not able to selectively eliminate the reflection from the light coming from a reflective surface.
Regular sunglasses are only able to absorb a certain percentage of the various wave lengths of light, whereas polarized sunglasses basically work like venetian blinds, as they allow the vertical component to enter the eye but cut out the horizontal component that becomes the glare and therefore the problem.
