The Visiball lens technology combines basic principles of physics, visual physiology, and perception to significantly enhance the visibility of your golf ball.
The underbrush of a golf course is predominantly made up of browns, greens, and blacks (mostly reflecting from dirt, grass, bushes, twigs, etc). Visiball Golf Ball Finders use special blue filters that eliminate all visible wavelengths except those at the blue end of the spectrum. These special filters virtually eliminate light reflecting off grass and the dark objects of the underbrush, thus high lighting white golf balls. Most dark objects show up only as outlines while the white golf ball appears to glow with a slight blue tint.
