Avatar 3D, blurry vision

Went to see Avatar in 3D tonight. Typical story, but the animation was amazing. The 3D was also better than what has been out there. But darn, for the past 4 hours after exiting the theatre I have been having my vision still be in stereoscopic mode or something. I see everything beyond 1-2 meters as blurry, as if watching the movie without glasses. Hope a good night's rest will cure that.
