I think these glasses really work. I sleep a lot better wearing them when I'm looking at the computer or TV screen at night. BUT I wore them one night, about 3 weeks after purchase, and one of the parts of my nose just fell off. I'm not rude with my things and I don't drop them. Even if the product "works", I still can't give a good review if a piece of it fell off less than a month after purchase. Really, I have a pair of $5 reading glasses that have lasted over a year and cost considerably more. Just an update, I reported the defect to the seller/manufacturer and they promptly gave me a full refund plus a 50% discount coupon. to replace a pair if I want. I hope my feedback will help you make improvements.
