发明名称 APPARATUS FOR ENHANCING VISUAL PERCEPTION OF SELECTED OBJECTS IN RECREATIONAL AND SPORTING ACTIVITIES
摘要 PURPOSE: An optical apparatus is provided to enhance visual perception of selected objects in recreational and sporting activities.

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 (706), but passes a substantially lower percentage of light in the remaining portion of the visible spectrum.
