I personally have been wearing Maui Jims sunglasses for twenty years. Never had one problem with them. My eye doctor will not carry any other brand.
I own every shade they make. Dark black lenses for the water and snow. Brown for cloudy days. I have the glasses with the 150 x's bi-focal on the bottom so I can read maps and see my knot tying better. I own six pairs and never had one problem with lenses coming loose, scratches, frames becoming crooked or warped from the hot sun. A great product with a great warranty.

Good luck with finding the pair that makes feel comfortable and happy. That's what it's all about.
