I never buy expensive sunglasses, as I either sit on them or lose them. Hence, they never last past a month. HOWEVER, I purchased a pair of Steve Madden leopard print sunglasses from Marshall's during the summer and they have lasted so far! I drop them all the time, too, and the lenses never pop out. Nor, have the lenses scratched. They also have 100% UV protection and have no glare. I love them!
