If you are autistic, you could be over sensitive to light, a condition called photophobia. I have photophobia, but remedied the iritation using Transition lenses instead of normal prescription ones. I also have hyper-acuitism, so I hear things most people don't notice, and high-pitched/loud noises are more painful than for the average person. If you have a neurologist, pyschologist, etc., you should bring those possibilities up with them. And again, if you're autistic, you may be having trouble sleeping due to anxiety. I sometimes can't sleep because I feel that it's just "un-productive."
