Polarized vs nonpolarized

Postby mac336 on Tue Aug 23, 2011 9:17 pm

I debating between picking up a pair of polarized and nonpolarized oakleys. Are polarized lenses better for cutting out harmful rays? Also do polarized lenses have a different color tint when you wear them (do polarized lenses make things darker or lighter than normal lenses?)

Thanks for the great post. Light reflected from surfaces such as a flat road or smooth water is horizontally polarized. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a horizontally direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare. Polarized sunglasses cut glare and haze so your eyes are more comfortable and you can see better. Polarized lenses help with contrast and visual acuity. Polarized lenses contain a special filter that blocks this type of intense reflected light, reducing glare. When a lens contains this filter they appear darker than non-polarized lenses.
