I wear glasses so I never go to 3D movies, I end up looking like a twit wearing them over my glasses and I get a headache from the double lenses.
I can at least deal with that for real-d and LieMAX 3D, which use polarization. Dolby 3D and Imax laser 3D both use the 6p method, which results in a foggy haze around the image if you’re wearing prescription glasses (haven’t seen a movie in either of those formats, it’s just what I’ve heard). I’m long overdue for a new prescription anyway so I’m just going to get new contacts as well.
