Simulations of visual stress symptoms 

These include illusions of shape, movement and colour in the text, distortions of the print, loss of clarity, and general visual irritation. These may impede the development of reading skills and reading fluency. These sample distortions have been described by individuals around the world. Individuals often experience more than one distortion at a time, and the speed of movement will vary from person to person.

Note: Depending on the speed of your computer system, these simulations may move rapidly and/or take a few seconds to load.
