Irlen Syndrome (Scotopic Sensitivity Syndrome)
Irlen Syndrome (also called Scotopic Sensitivity Syndrome) is a visual perception disorder. To somewhat understand the condition, take a newspaper, wrinkle it and keep making waves in the paper while you try reading an article. For persons with Irlen Syndrome, text can appear to move, swivel, become very big or very small. Text can appear like the picture above.
Irlen Syndrome affects the way the brain makes sense of printed information. The problem does not arise because of poor eyesight. People with the problem see printed pages differently. They may however be ignorant about the fact that they do, but it negatively affects their reading abilities.
