As someone who has spent most of life around fluorescent lights, LCDs, LEDs, etc. etc. this has been one of the greatest investments I have ever made. I love them more everyday.
You may be familiar with the concept of blue light. For those of who aren't, it does bad things to your eyes. Having spent years in typical offices (fluorescent lights, flat panel computer monitors) then coming home to play video games, watch anime, etc. my eyes would get in bad shape. Burning, dry skin around my eyes that would fall off and go into my eyes, tiredness, pain…all kinds of bad symptoms. There have been times where I went to sleep so I wouldn't feel my eyes burn anymore from the blue light.
Absolutely no resemblance to the type of blue light that is bad for you.
I sought a solution and game across Gunnar glasses. The science behind the lenses was good, the reviews were good, and the results...completely blew my mind.
Almost every eye-related problem I've ever had (save for being born with astigmatism) went away in a matter of hours. All of the fatigue, all of the burning, all of the dry skin...literally every physical ailment related to my eyes that drove me nuts for more than a decade went away instantly. I wish I knew about these a lot sooner. I can't give Gunnar a high enough recommendation.
Computer Glasses or Gaming Glasses?
They don't do a very good job of explaining it on the site, but there is no difference in the glasses themselves. The eye protection is exactly the same either way. Gaming glasses are thinner behind the ears and designed to allow you to comfortably wear a headset/headphones. The computer glasses are rather uncomfortable with headphones, as I found out first hand.
Being an otaku you might go for the anime glasses as I did (they are similar in style to the rectangular glasses you see in anime all the time), but I would NOT recommend them at all. While they look great on the right type of face, the lenses are actually very small. Not only does blue light still leak in from the sides, top and bottom, but I can see the edges of the frames at all times. You get used to it after a while, but it's still distracting. Knowing what I know now I would buy the Desmo frames instead.
The yellow lenses are what you want (they offer more protection), but if you're a graphical artist or something similar that requires colors to be 100% perfect all the time the clear lenses will protect you as well. I don't have any clear glasses so I can't say what the difference is as far as blue light blocking, but Gunnar admits they are less effective.
For those needing a prescription in order to see, they offer rx glasses for an additional fee, as well as reading glasses if you happen to use those all the time.
