Coming up on 2 years since purchasing these sunglasses, and they are holding up OK. I wear them every day, as I have minor photo-phobia from an eye issue and they help a great deal with bright sunlight.I've had some trouble with the ear pieces coming out of the frame when I'm taking them off - but a little glue and they are back to normal. This could be related to using them with a neck strap that slides over the ends of the glasses putting unexpected pull on them.The general quality and the price are OK - I would buy these again
