Why you need UV protection glasses? The sun has damaging UV rays that can cause photokeratitis, pingueculae and permanent retinal damage. The sun's rays are strongest between 10 a.m. and 2 p.m., but that's not the only time UV rays can affect your eyes. Also, most people think that they're at risk only when they're outside on a sunny day, but UV light can go right through clouds, so it doesn't matter if the sky is overcast. Glare and reflections can give you trouble too, so have your sunglasses ready if you'll be around snow, water or sand, or if you'll be driving.

Why you need prescription polarized sunglasses? Light reflected from surfaces such as a flat road or smooth water generally is horizontally polarized, This creates an annoying and sometimes dangerous intensity of light that we experience as glare. Polarized lenses contain a special filter that blocks this type of intense reflected light, reducing glare.
