Irlen Syndrome ®

Irlen Syndrome means light causes problems with reading, attention, headaches, fatigue or depth perception. It is about the brain's inability to process visual information.

It is not a problem with the  eyes, it is a problem with the brain. Many people might not realize their reading challenges are related to light or they think their symptoms are normal.  

For example, some people say they “don't like to read” when it's really hard for them to read because of their symptoms (eg: can't concentrate, get sleepy, words move, can't remember what they read, etc.) Irlen Syndrome is a sensitivity to light that creates distortions on the page, especially with the contrast of black print on a white page.
