HOW DO POLARISED LENSES WORK?
Light reflected from surfaces such as a flat road or smooth water generally is horizontally polarised. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare. Polarised lenses contain a special filter that blocks this type of intense reflected light, reducing glare. For most other sports and activities, polarised sunglasses offer great advantages.
