Anyone who is not familiar with the benefits of using continuously polarizing glasses, owes it to himself to ask an eye doctor.Anyone who is not familiar with the optics behind polarizing lenses owes it to himself to ask a physics major to explain.Let alone the fascinating applications of polarizing filters in science, engineering and photography. Absolutely fascinating.
Really surprised by quality for the price. My husband loves them. Lightweight and u can’t see a person’s eyes when on.These are ok. I liked the frame, but I live in southern Arizona so they didn’t quite provide the eye protection I needed. It’s nice they came with a cloth and a case though. Worth $20, but I found some on here for $10 that are better.
