Polarized Sunglasses for Driving

DrTavel.com, a good source of information regarding vision and eye health, recently had a posted review on polarized sunglasses. Polarized material basically filters out certain orientations of light (this is complicated enough to do a series of posts on), allowing you to only see certain sources of light. Many 3D glasses work this way.

Anyway, here's an excerpt from their blog:

A few days ago I went to pick up my vehicle (which looked good as new) at an auto repair shop on the eastside of Indianapolis. Since I live and work out west, I never take the highway going west in the afternoon. The moment I jumped on 70 west, I was almost blinded by the glare of the sun. Luckily I had a pair of Ted Baker sunglasses with Purifier® polarized lenses from Dr. Tavel. I immediately put them on and continued my journey west.
