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.

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 - 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.

Trash scam company After they got my money they went completely silent don't bother about my order anymore, it has been a week now and they even didn't ship it yet and no track number! this is ridiculous, don't buy from them! Upd: They are completely ignoring me now, no information about my order no tracking number provide. Trash company, don't want to refund me

Scam Company, do not buy Months I reaches out to GMG performance to request a replacement pair of glasses. After sending the company a couple of photos of my broken glasses, GMG performance said that I did not have a warrant with them, but if I give them a good review on trust pilot, they will send me a free pair in the mail. Now a month after my previous 5 star review for them, no glasses have been sent and customer service will not respond to emails
