From the Irlen Institute, founded by Helen Irlen in 1983: said:
What is Irlen Syndrome?

Irlen Syndrome (also referred to at times as Meares-Irlen Syndrome, Scotopic Sensitivity Syndrome, and Visual Stress) is a perceptual processing disorder. It is not an optical problem. It is a problem with the brain’s ability to process visual information. This problem tends to run in families and is not currently identified by other standardized educational or medical tests.

It sounds like this might apply to autism, brain injury, or other conditions...

I looked into this a lot when I was much sicker I had pretty much all the symptoms but over time it has gone away, it comes back in a bad crash and I have found avoiding glutamate helps hugely.
