My husband loses his glasses. They are always falling off. When he was in single lens I would buy several pairs at a time. As he moved to progressive lens that was no longer feasible. We're on the 3rd pair of progressives since September (6 months) but I think these are going to work great, rather than straight arms, these curve around the back of his ears. No more falling off. He says they are the best glasses he's ever had and less than a third the price of buying at the optometrist office! 😊👍
