It's occurred to me that quite often when I go to the cinema I end up with a migraine. Sometimes this happens during the film, sometimes the next day. Sometimes I'm probably going to have one anyway, and it's probably the cinema experience that's tipped me over the edge. Television doesn't do this to me, though computer screens & mobile phone screens can.
3D seems to be a big culprit - I don't quite get the special effects & would prefer a good old-fashioned black & white film any day. Last week I had a bad time the day after watching The Hobbit in 3D, and at times had to close my eyes because the action on screen was making me feel seasick. The trailer for the film was an extra long preview of the new Star Trek movie, which made me feel quite ill. (Not a Treckie, so missing this won't be any great loss).
Even a normal film can be a bit much and it depends on where I sit. Too far at the front and my neck's in the ideal position to cause problems. Too much in the middle & higher up & it feels all right in my face. Saw a film a couple of years ago called "The Tree of Life" (with Brad Pitt - wish I hadn't bothered) - the cinematography was great but to me the colours were far too bright & guess what happened?!
I've flicked through Dr. Oliver Sacks' weighty book "Migraine" again, and read that he had a patient who could get migraines from something as innocent as a button on someone's coat being a bit askew. I suppose all those vivid images must be doing something to upset the delicate balancing act going on inside my brain.
But I'm not going to give up rare trips to the pictures -it just means planning it a bit better with regards to getting a good seat, and maybe cutting out the 3D ones. I won't be buying an e-book type machine thingy either, though that's because I'm a Luddite.
