As is well-known, sensory hypersensitivity is common in the autism spectrum. For visual or optical challenges there are two aspects – control of the lights used to illuminate classrooms and living spaces AND protective eyewear.

As it happens, there are a number of causes of visual hypersensitivity: (1) medications like tetracycline and digitalis; migraine headaches; some types of dyslexia; meningitis and lupus; as well as some types of macular degeneration and cataracts. There are certainly night blindnesses that are caused by vitamin shortages – typically of vitamin A, C, E, lutein and beta-carotene.
