I didn't suffer a headache watching the 3D version of Avatar, but I did suffer a bit of eye strain. It was to the point I had to rest my eyes for a few seconds by either taking off the glasses or shutting one eye.

Te me items that should have been close to me were just blurry, and almost double vision. Andym was sat just a couple of meters away and didn't get that, so it's my eyes not the projection. Objects at mid distance were ok, but the overall effect isn't what I call 3D (like real like is!

I figure that making a 3D system that works for everyone must be nearly impossible. I'm just a bit unlucky that the effect just isn't worth it for me to ever watch another 3D film.

Cheers
