Stellar! When I ordered from them they sent me an email welcoming me to their community and giving thanks. Shortly later I got the glasses that I ordered and they worked really well and allowed me to sleep better and have less fatigue in my eyes after being on my computer all day.

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 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 glasses for gaming. I ordered these glasses to help with headaches while using screens and it helped a lot. I used to suffer from headaches and eye strain during long gaming sessions or when watching my tablet before bed. Wearing these glasses while doing those activities has totally eliminated those problems. Very happy with the functionality.

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.
