Great glasses! These glasses are fantastic! I work behind a screen then game afterwards. I was dealing with eye fatigue/dryness, headaches, and trouble sleeping. I tried a few brands of blue light blockers, and none hold up to GMG. Not only do they look stylish, but they'll help your eyes not feel terrible after extended sessions behind a screen. I definitely recommend for anyone that works at a computer or likes to game.

Scam Company, do not buy Months I reaches out to GMG performance to request a replacement pair of glasses. After sending the company a couple of photos of my broken glasses, GMG performance said that I did not have a warrant with them, but if I give them a good review on trust pilot, they will send me a free pair in the mail. Now a month after my previous 5 star review for them, no glasses have been sent and customer service will not respond to emails

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

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

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.
