I can literally say that these blue-blocking glasses have been a game changer for me! As part of my work, I spend a lot of time in front of the computer, and I struggled with eye fatigue and headaches, which have improved significantly after starting using these glasses. There is no question that these glasses work! These guys have done an amazing job with the lens coating, as I have oily skin, and I always struggled with getting smudges off my glasses. This is a non-issue here; everything comes right off without any effort! The frame is robust (you feel the quality) and sits comfortably on the face, and they look very stylish. Great price when you look at all the specs. Highly recommended!
