Mark me as another one with inperfect eyes,
I have an astigmatism, this prevents me from
seeing the old sterio graphic (red/green glasses)
3d movies, but for some reason the tech they
uses with the polarized 3d glasses seems to work
on me, so I was able to see Avatar ok, but it
gave me a wicked headake for the first 1/2 hour
untill my eyes got used to the forced perspective.
