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.

GMG Optimizer - Mat I purchased of pair of the GMG Optimizer - Mats to wear while working from home towards the end of 2020. I had noticed myself starting to get minor headaches from staring at my screens all day and saw an ad for a discount on these glasses from a YouTuber around the same time. I decided to take a chance on them and I am happy I did. I was able to work long hours (CPA at big accounting firm) and no longer experienced headaches from my screens. Same goes for gaming. Often, after clocking out, I'd immediately hop in a 1-3 hour gaming session - and the glasses performed well there as well. I definitely recommend giving these a try if you experience headaches from your screens.

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

GMG performance glasses Not only for gaming but as someone with a very busy school schedule these glasses have quite literally saved me the headaches from looking at computer screens for prolonged hours of studying. I noticed the difference within 2 days of using them and don’t see myself taking in all that blue light with unprotected eyes anymore. My sleep quality went up after using them as well. Overall an amazing product that’s worth checking out if you find yourself in front of screens often.
