re: Anybody use computer/gaming glasses?

They are a total scam. That's not to say there aren't some benefits. Just not enough for the price you pay for them.

For one thing, they are nothing more than tinted low-power reading glasses with an anti-reflective lens coating -- the same coating they offer you at LensCrafters, WalMart Vision Center, etc.

I wear prescription reading glasses -- +0.50 in the right eye and +1.25 in the left eye -- and I generally get my glasses from eyebuydirect.com on a buy one get one free/half off or whatever special. I've tested four pairs. One pair has the anti-reflective coating and UV filter and serve as my everyday glasses. The second pair is the same and just serves as my backup pair.

One of my "free" pairs is just plain jane plastic lenses with no coatings. When doing computer work, this pair does have a noticeable glare effect over my others that bothers me at first, but I eventually get used to it. It probably does cause some eye strain.

My other free pair, I decided to mimic the "gaming glasses" features by applying a 20% yellow tint + the other coatings my normal glasses have. No surprise there, they're like my normal glasses but everything's a bit yellower. I understand the point of the yellow, which is to filter most of the blue light that fricks with our circadian rhythm, and the tinting reduces some "glow" from the monitor that might further reduce glare or contrast sensitivity. In practice, you're just seeing yellower stuff. I have a 1440P IPS monitor with beautiful color depth and accuracy, and I'm not going to alter that with yellow glasses. So, that pair stays in a drawer. I'll also add that I've tested Gunnars in Best Buy that are essentially identical to my yellow tinted reading glasses, except text is not as sharp since they don't have as much magnification as I need.

I would say, if you don't currently wear glasses or contacts and you're experiencing eye strain, I'd go get an eye exam at your local optometrist and see if you wouldn't benefit from some reading glasses. The most noticeable benefit from any lenses will be the anti-reflective coating.

With the "computer" glasses like Gunnars, I'm sure there's a lot of placebo effect. After one spends so much on plastic lenses and frames, it would be tough to admit they're useless.
