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.

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 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.

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

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.
