Great glasses, help my focus I've been using these glasses for the past 2 years or so and they have been a tremendous help in keeping me focused and reducing blue light so I fall asleep easily. The customer support is great helping me in any way they can :) 10/10 would come again.

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.

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.

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

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
