Gunnar Optics

I hate to admit it, but I think I may need a pair of Gunnar Optics. I'm diabetic, so my vision's already bad enough. On top of that, all I do all day is stare at my computer screen. While I'd probably get a lot of sh*t for wearing them, I feel like they'd really help me. Hell, I've even got the lights off right now because I can't see the screen well when they're on (yeah, yeah, I'm not doing myself any favors). What do y'all think of Gunnar Optics? Do you have a pair? Do they help? I'd appreciate some feedback, especially if you have first-hand experience with them.
