Abstract
To enhance perception of a yellow tennis ball while playing or watching a tennis game, the game is viewed through an optical filter mounted between the participant or spectator and the ball. The optical filter has predetermined transmittance having a pronounced peak centered substantially around 500 to 600 nanometers that passes a high percentage of incident light reflected and fluoresced by the tennis ball, but passes a substantially lower percentage of light in the remaining portion of the visible spectrum.
