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.

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

Great Glasses, just small frames or a big head. So I’ve had my glasses for about a month and change and they’re honestly great. Got the Optimizer frames and my eyes are doing a whole lot better with blue light protection. I can sleep almost immediately after playing games now and it’s fantastic. Only reason it’s not a 5 star is because the frames are a BIT small. Can’t wear my headset for a long time because they’ll destroy my ears, but after a while I’ve adjusted. Not sure if they offered bigger frames but if it’s my fault then it’s an automatic 5 and I’m just a dumbass.

Great glasses! These glasses are fantastic! I work behind a screen then game afterwards. I was dealing with eye fatigue/dryness, headaches, and trouble sleeping. I tried a few brands of blue light blockers, and none hold up to GMG. Not only do they look stylish, but they'll help your eyes not feel terrible after extended sessions behind a screen. I definitely recommend for anyone that works at a computer or likes to game.
