What are visual perceptual distortions?
Some people can experience distortions when they look at certain materials, particularly text. The distortions of text include blurring, movement of letters, words doubling, shadowy lines, shapes or colours on the page, and flickering. These distortions are characteristic of a condition that some have called Meares-Irlen Syndrome, Irlen Syndrome or Scotopic Sensitivity Syndrome.
