Seeing as I've been using 3D gaming since 2001 (NEC 17 Inch CRT 1024x768 @87hz) and I've yet to have eye issues, I'm fairly certain that there won't be any health risks. What's really happening is people's who are new to "3D" don't know what to do with it. Your trying to focus your eyeballs on something, STOP IT. Relax your eyes, don't try to focus on virtual objects, instead let the 3D engine do the focusing for you. Learn to focus at the screen and not at the visual tricks. It takes getting used to but once your comfortable doing this then it becomes so much more immersive. Games are awesome in 3D, and movies can be too, provided they don't try to go overboard and kill you with it. Thor is a really good movie to show how 3D could be done right, they used it heavily for the backgrounds of the Asguard and some of the special effects.
Anyhow this seems to be really nice, you can add 3D support to any LCD device, although it'll be half resolution it's still nice.
