Nope, I don't get dizzy. But I once sat very far to the side in a 3D movie and then the images did not completely overlap, so they had a double edge. If that explanation makes sense? That was initially irritating but after a while I could ignore it, until it started annoying me again. Thus, more strenuous for the eye than sitting in the middle and distracting.
Apart from that, well, 3D is fun but it's not all it's cracked up to be in my opinion.
Now you make me wonder, do you also get seasick?
Ouch, that is even more than here (I just googled the conversion rate of AUD to DKK).
