With computer I spend more than 10 hours per day of screen time and am very happy with this purchase. These glasses are very surprising, we immediately feel the difference at the computer or console. Pikes eyes much less, more sensation déblouissement, lightweight zoom the picture significantly, whites no longer attack the eyes. At the office I have a neon lighting from above, it stings after a while ... and they are large enough and cover both eyes, I am not dazzled by the neon lights above. The most surprising is on the computer, the difference in contrast without glasses and with glasses, is obvious. Come in a pretty box with hard case + a classy fabric sock: it all, at this price? Nickel. Small defects noted in my opinion: they are not completely anti reflection, they are a little heavy on the feel good on the nose.
