Excellent customer service Excellent customer service, answered questions quickly and resolved issue I had with a scratch on the lense easily. Really happy I purchased them and have recommended them to friends. I would opt for the gamer version as they block more blue light than the other models.

Worst company Worst company. They took 2 months to send me the glasses, and when I called my bank to cancel the transaction which they did and when my bank contacted them they asked to me to take back the complain and they were going to refund me. It's been 3 months now and I'm still waiting for the money. I'm not the kind of person who will put a review even if I'm not satisfied with the service but honestly I never seen something like this before.

Expensive price tag on cheap quality Arrively in reasonable time, but the product itself is pretty flimsy & cheaply made. Not worth the money kooper are charging.

terrible quality I bought a pair of blue light filtering glasses and my first impression was the overall quality of these glasses is terrible, something you would find at a Skegness market. The lenses wobble within the frame, the lenses were scratched, and the frame itself is made from very cheap plastic to the point where it feels as flimsy as the glasses you get from the cinema to watch 3D films. I can say that the lenses do filter blue light and do work In that aspect but I would not pay £30 for another pair again.

Sore eyes / Headaches / feeling sick has all stopped. Highly recommend. I’ve had my ‘Charlie’ glasses for a couple of weeks now and use them daily - they’ve genuinely made a massive difference to my eyes and head when I use my phone so much. When I’m sat waiting at work or at home I’m on my phone loads and my eyes had really started to struggle, like headaches and feeling sick - honestly don’t get that anymore when I wear the glasses. I also really like the way they look and keep getting compliments too so that always handy! Highly recommend.
