I got readers/computer glasses about a year ago to help with focus issues and fatigue. They added the blue light filter and they are clear as clear can be. I LOVE them. My husband is director of IT at his firm, and he is always looking at screens. He has a pair of blue-light filter glasses JUST for this reason, and he wears them almost all the time, lol. He swears they help him with night driving, because the lights of oncoming vehicles don't glare so much into his eyes. I think they do reduce eye fatigue.
