I've been starting to have issues with the upper right quadrant of one eye, in which the vision has been double for over a year now. The effect of one small portion of your perception being out like that can be quite disorienting. Night driving can be almost impossible, racquetball (which I've recently taken up) is proving itself quite the challenge with all that bright white. Things start to distort and a layer of lace starts to fall over over my vision. If I weren't so busy trying to see 'normally' it's actually extraordinarily beautiful to see lights refract and the world melt into something different. I can only imagine trying to deal with ALL your senses, well, I'll use refracting for lack of a better word, like that. There is another video as well of a teenage autistic girl who talks using a computer in much the same way about the sensory overload that comes with autism and why they retreat into their own bubble the way they do. Having fibro, when my nerves overload, I can only imagine that's perhaps, what, 1/30th of what they feel?
