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.
