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.

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.

Amazing glasses! I received my glasses on the 5th of July and my experience with them since then has been more than satisfactory. They're comfortable to wear and are very stylish, and I've had less headaches so I can continue gaming with my friends. GMG Performance is the real thing, their glasses really work as advertised. 10/10 would recommend!

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.
