Abstract: A method and apparatus for increasing the visual performance of athletes. For example, a baseball hitter is taught to recognize the spin of a thrown baseball and thus become a better hitter. A hitter wears eye glasses having lenses which are tinted in a color which is complementary to the a baseball being all or partially tinted in a complementary color. For example, the hitter may wear green tinted lenses to make the red seams of the thrown baseball become much more apparent. Various complementary color schemes are disclosed. Several examples of specific practice for use of the method and apparatus are disclosed. Examples of sporting activities in which color recognition is useful include baseball, shooting, soccer, racquetball, handball, volleyball, tennis and others.
