I have ordered 4 to 5 pairs of these items and there is a very nice and a very cheap version. It is unknown which version you will receive. Both versions filter out blue light well, but the cheaper version sits horribly on any face, is uncomfortable to touch or wear, and breaks very easily. Of every pair I've bought in the last five months, one pair has lasted. I recommend blue light blocking glasses but I would buy elsewhere and probably not Revain as you never know what you are buying!
