Blue Light Blocking Glasses Computer Screen Reading Glasses Unisex Lightweight Eyewear Frame Clear Lens Anti Eyestrain and UV Gray

These seem like well made glasses and aren't flimsy. However, they're advertised as blue light blocking glasses, and they seem to have no effect as far as blue light is concerned. Initially I thought perhaps it was just me, but five other people have looked through them and can see no difference at all. Ordinarily, blue light glasses noticeably block some of the glare from your screen, especially when reading at night. Again, I see no difference with these glasses, but your experience may be different.

These glasses were unusable. The lenses were warped.
