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.

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.

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.
