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

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

Great glasses, help my focus I've been using these glasses for the past 2 years or so and they have been a tremendous help in keeping me focused and reducing blue light so I fall asleep easily. The customer support is great helping me in any way they can :) 10/10 would come again.

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.

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.
