These glasses are surprisingly well made and the lenses are crystal clear. I was very impressed with the weight of the glasses - they feel as heavy as my Ray-Ban Clubmasters (same style of glasses). They look very high quality. I would confidently put them next to any Ray-Ban set and wouldn't be disappointed. Keep in mind that these are larger lenses than you might think. I've attached a photo of them compared to my regular size Ray-Ban Clubmasters. The difference is small but noticeable. The packaging was a bit wrinkled but fortunately not damaged. The kit includes a tester with a photoreactive card. Of course, these glasses absolutely passed the test - the color does not change when looking through the lenses! Now to the point of these glasses: blue light blocking properties. I've been using them for a few hours now and while my eyes don't get as tired as they do without lenses, I feel they are less able to block blue light than my BlueCut brand glasses (also available here at Revain). I'll update this review after using it for a few days to give you a better idea but for now; I would say there are other, stronger options.
