I have the Ray Ban 4115 wrap around sunglasses and needed new ones so I got these because they do not make the 4115s any more. I really like the 4283CH style sunglasses. The lens are bigger and offer more protection from the sun. I have heard complaints that these were too big. My head is not big, size 7 hat, and these fit great. I have the black frame and blue lens and they make the colors brighter and have a slight yellow tint to the green lens, that is a good thing for my tastes. I was a little concerned that they would be too big but no problem for me.
