Hi I'm 29 and am also autistic and sensitive to light and really sensitive to sunlight. I have now been diagnosed with irlen syndrome and wear a special pair of tinted glasses. They really help I don't get headaches anymore or migraines and vomiting. Computers also use to give me headaches and hurt my eyes.
Hi!
I am sorry to hear about your medical problems. Retinal detachment (this also causes flashes of light), iritis, uveitis, optic neuritis, corneal ulcerations and other afflictions of cornea, and cataracts are a few eye related causes for increased sensitivity to light. It can be due to nervous system disorders like herniation of tonsils or Chiari malformation, meningitis and encephalitis. The latter two you obviously do not have as you do not have any other symptoms. Chiari malformation can be diagnosed by a MRI of the brain. Other than that it can be a symptom of migraine, retinal migraine, ophthalmic migraine, magnesium deficiency, infectious mononucleosis (if you have a recent history of flu like symptoms), chronic fatigue syndrome, hangover, side effects of certain drugs etc.
Please consult your PCP for primary examination followed by proper referral. You need to consult an eye specialist and a neurologist. Take care!
