I am not trying to be a smart ass here but I seriously don't understand how a flashing low powered lighted necklace can cause a seizure or a migraine but the bright flashes of Illuminations or Wishes or Fantasmic do not cause one. Is there an explanation for that? I just don't know. Could someone explain it (in simple terms) please?
I can't tell you how they effect every one, I can only tell you that it's not the necklaces but the toys (the buzz lightyear ones that spin and flash, and the ones that have tinkerbell I think? I couldn't see them that well) that flash repeatedly in the same pattern, with a child standing right in front of me holding it, that gave me the problems. I have never seen F! (the wait for the show always seems too exhausting somehow, at the end of a studios day, I don't know why) so I don't know how it would effect me. But Wishes and the fireworks part of Illuminations doesn't bother me (I am careful not to stare at the globe as it spins though)GaTechGal wrote:Ya'll check me if I'm wrong, but I think it has to do with light intensity and flashing speed. Proximity might have something to do with it too. Since the fireworks are SOO far away from you the intensity isn't as bright as a flashlight 5 feet away. Also they don't repeatedly flash over and over several times a second. With fireworks, it's a big flash, but it lasts for several seconds. Same thing for the lasers at F! They are further away, and being projected onto something else so the intensity is less.
If I see a flashbulb go off, I can't see for several seconds afterward. I see 'shadows' over my vision, I have cataracts and a bunch of other eye problems that I'm too tired to explain here in addition to my post-stroke neurological deficits, which include (for the curious who asked :) left-side weakness, gait instability, loss of balance and depth perception, lost visual fields, all usual stuff.
So all I can tell you is that no, the fireworks do not bother me, but yes, the flashy toys that repeatedly flash the same pattern, quickly and consistantly, do. Sorry I can't describe it any more indepth than that.
I've heard about cartoons or music videos being edited together so quickly that they were causing people seizures. They even joked about it on the simpsons LOL. It's the speed and the flashing, I think that is the problem.
