At first I bought it myself. Second, they are great! I have already ordered 3 more pairs! I leave a few at work and keep 1 at home and gave my mom 2 to do the same; more as a gift for the holidays in the office and a souvenir for stockings. Of course I don't know what effect they will have on my eyes decades from now, BUT the color difference is very obvious with and without glasses. And for under $20, it's worth a try! And they're really cute, that helps!
