At first I was skeptical. Hmmm... HD Vision ? What a bunch of marketing BS. They look like AmberVision to me. Then I saw them on sale for $9.99 and I tried them on. They are light, comfortable, they look good. I use them at work 8 hours a day and they never feel uncomfortable or fall off my nose when I bend over to pick things up. The world looks amazing and bright and I do not squint in the sun. They are also brighter than dark sunglasses when you step indoors. The HD claim might be bogus, but the functionality and price are the real deal. I went back and purchased two more just in case they get discontinued. Buy a couple pairs for yourself and buy your old lady some Ray Bans with the savings. (Make sure you are getting the normal "surfer style" ones. Not the "old man" wrap arounds with the side windows). Unless you are into that :)
