Terrible company to deal with
The glasses I received are very thin and light, they would have been ok except that I ordered blue block lenses and paid additional for them but I was supplied glasses with clear lenses making them unusable for screen work! I tried to speak to customer services about the problem but they refused to acknowledge that they had made a mistake so I'm left out of pocket with unusable glasses. I wouldn't trust this site as they are dishonest and poor quality. My advice is spend a little more and get decent glasses from a more reputable company!
