I have purchased 3pairs but 2 of them don't work properly I just barely used them and they bothered my eyes. I will try them later to see if they work if not I will just use the one good pair that is so comfortable. Overall the products are good.
Tip for consumers: I love the colors and products but I am just having trouble with 2 pairs that are giving me trouble.
Products used: I used 1pack of the 3 that I purchased.
