Great Product and Customer support I have been using my GMG Optimizer's for a year and a half now on a daily basis, they feel comfortble to wear for long hours without putting any strain on my eyes. I also had some minior issues, in which they provided me with quick and excellent customer support. I highly recommend for customers looking for affordable and effective blue light filter ining glasses.

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.

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.

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.
