Great replacement for my Ray-bans. Not as heavy as the actual glass lenses of Ray-ban but still good quality.

These lenses are light yet sturdy. Can tell if he difference from original

These polymer lenses are very light and the reflective coating looks great. Unfortunately they began to degrade immediately. Because they are plastic they are more susceptible to scratches which was a known issue buying them. What I did not expect was the metal reflective layer to delaminate after a quick rinse with hand soap and water. I would not suggest this brand of lenses.

the lens fit fine, my frame was slightly F'd up....but the lens fit fine.

I didn't buy through Amazon but I actually do own them. I purchased to replace broken lens on my almost brand new aviators. These lenses are plastic not glass. Up side is they are much lighter on the nose than originals. They are indeed polarized and I do like that. Being plastic they are optically inferior to the original polarized glass lenses. Objects appear to be wavy or out of focus in some areas. I've had them for some time now and I have gotten more used to them so that doesn't seen to bother me as much as when they were new. What I really hate about them is the fact that they pop out of the frames, usually at the times I need them most. It is almost impossible to clean these lenses without at least one or the other popping out. They just flex so much and there is very little frame there to hold them. Also no cool Ray Ban P logo like the originals. I will likely buy a new pair of originals and keep these in my old truck.
