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.

These glasses are stylish These glasses are stylish, and functional! I work in front of the computer all day, and when I'm not working, I'm on my phone, or watching Netflix, or playing PC games so my eyes get strained from being in front of screens for well over 12hours a day. It's the unfortunate truth of our modern world. These glasses are exactly what I need to make sure my eyes are protected and look forward to using them daily.

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.

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.

Very good product I highly recommend I… Very good product I highly recommend I no longer have a single problem thank you GMC performance
