They have greatly helped my eye strain/dry eyes! I wear contacts and my prescription has always been really strong (bad genetics). But after I started wearing blue light blocking glasses, my prescription in 1 eye improved slightly, and the other stayed the same (after years of steadily getting worse).

Re: dry eyes, I’ve definitely noticed a difference when I don’t wear them. My contacts are significantly drier.
