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.

Trash scam company After they got my money they went completely silent don't bother about my order anymore, it has been a week now and they even didn't ship it yet and no track number! this is ridiculous, don't buy from them! Upd: They are completely ignoring me now, no information about my order no tracking number provide. Trash company, don't want to refund me

GMG Optimizer - A Student's Review I ordered a pair of GMG Optimizer - Mat back in November 2020 because I had headaches due to my online classes and I'm glad I did. Even if we're back in school, I still use them fairly regularly for late night study sessions and movie nights. I would appreciate if the glasses were a little larger but they still work very well and I've got compliments while wearing them.

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.

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