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.

Refund The glasses I received, I was not satisfied with them and decided to send them back and get my money back. It turned out that I had to do it at my own expense and send them to France to their warehouse. I have been waiting for the refund for 7 days and nothing, I wrote to them twice and no one responds very bad communication.

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.

Good product awesome support My first glasses was stolen from package on transit send a picture to courier and gmg performance. Courier did not even bother to be interested but got answer from gmg and they sent new pair of glasses. (Answer from gmg took about 72h so do not panic if you are waiting mail from support) Btw these glasses are comfty and stylish

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.
