These do have a positive effect on your eyes. They take a few days to get use to, but once you do you will thank yourself. They're only lightly tinted a yellowy color, so there's no crazy color shift from them. If you wear them while you game, long sessions won't feel like they're burning your eyes out. I could tell the difference myself, which is the reason why I continue to wear them.
They're made kind of cheap though and the lenses get fingerprints on them if you even look at them. But they do come with a case, which has a microfiber cloth in it.
Great for people who have to work on a computer all day long. They will prevent the headaches that will surely come.
