Review on Henotin Men's Eyeglasses with Blue Light Blocking for Reading - Essential Accessories by Chris Walker

I don't know if the glasses really block blue light, but for reading/computers they are really good. Very convenient. Fits good. Clear view without distortion. The lenses have a slight yellow tint, presumably to block blue light, but not to the point of making it look like colored lenses or affecting the color of what's being viewed. I am very happy with the glasses.
