I spend 8 hours of screen time work + 4-5 hours on my way home (PC + TV). Going to bed, my eyes were literally exploded ... I thought that by buying these glasses, I would feel a little improvement ... Well it's more than that, it has changed my life. Every night, it is as if I had not touched a PC of the day, I do not feel any eye fatigue. No more blur before my eyes, eyestrain what ... I can concentrate for hours of screen time without feeling any discomfort, it's prime. It works as well for hours of that office for hours of Battlefield 3 :).
Frankly great again :). HOWEVER: it is super expensive and super ugly (in my opinion of course), to have a design not too kéké it will spend 100 a pair, and I could not afford it. For those using a headset, the branches of these glasses are far enough away from your skin to not be annoying.
