Abstract
Vision testing and training apparatus and methods employ a rotatable turntable which is provided with a plurality of openings. As the turntable rotates, pegs are inserted into or removed from the openings by an individual who desires to test and/or improve his or her eye/hand coordination. By providing the apparatus with a rotatable disc containing vision-testing indicia in the form of printed letters and/or numbers, the apparatus can be used to improve one's eye tracking skills but not necessarily eye/hand coordination.
