The optical filter enhances the perception of a stationary white object such as a golf ball to help a user to locate a lost object. The filter attenuates light transmission for colors having wavelengths over 500 nanometer such as the light reflected by vegetation and transmits colors having shorter wavelengths such as reflected by the ball. The filter is worn in an eyeglass frame.
