I bought these because I had undergone a cornea transplant and needed to protect my right eye. My prescription sunglasses let in too much light. These were more fashionable than traditional wraparound glasses and were polarized to boot! They fit snugly over my eyeglasses–no fear of them falling off–and the vision through them is superb. I can sit on my back deck without fear of glare. I am headed to the beach in two weeks and I know I will be wearing these constantly!My only complaint is that one lens popped out after several months of wear.
These are great glasses, the lenses make everything very clear, even in rain! The bi-focal makes for a nice addition.Husband loves these sun glasses.
