Vision Therapy exercises
These tools and mini-games are designed for use under guidance from a vision therapist. Some of the tools are modeled after existing games, and can be played as regular games.

- Keep your eyes focused on the middle circle. Click the circle, or press the spacebar to display the target marker/letter. Using your peripheral vision, locate the corresponding marker in one of the outer circles. Try to click the target marker without moving your eyes away from the central circle. A correct click will result in a green flash, and the central circle will advance to the next target marker. The central circle will flash red if the wrong target marker is clicked.
- Instead of clicking the targets, you may use other means of identifying the target marker (eg, by placing a stick or physical pointer and verifying the correct target by looking there). In this case, press the space bar to advance the central marker to the next target.
