Good product awesome support My first glasses was stolen from package on transit send a picture to courier and gmg performance. Courier did not even bother to be interested but got answer from gmg and they sent new pair of glasses. (Answer from gmg took about 72h so do not panic if you are waiting mail from support) Btw these glasses are comfty and stylish

My experience When I first got my glasses last summer, my headaches went down from the dramatic decrease of blue-light directed into my eyes. Worth the money, and the customer support is TOP NOTCH.

Very good product I highly recommend I… Very good product I highly recommend I no longer have a single problem thank you GMC performance

One very satisfied customer Got a pair of the gold frames. Honestly can say that it has helped me avoid several migraines, as I work almost entirely on a screen on a daily basis.

Well at first there was some issues… Well at first there was some issues with getting back to me and my order not being shipped but I think it was just because of how busy everything has been. I do like my glasses a lot because I feel like my eyes don’t really hurt like they used to.
