Sample distortions in text
WARNING: The following images can cause discomfort and trigger seizures in patients with photosensitive epilepsy.
These simulations demonstrate illusions of shape, movement and colour in text. These are common distortions that lead to loss of clarity and general visual irritation.
These may impede the development of reading skills and reading fluency and may cause mild to severe headaches or migraines. These sample distortions have been described by individuals around the world. Some individuals may experience more than one distortion at a time, and the speed of movement will vary from person to person.
Note: Depending on your computer system, these simulations may take longer to load and may not display at a realistic speed.
Animated simulations are not available on our mobile website.
