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.

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

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.

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.
