  • Publication number: 20060158605
    Abstract: This invention provides binocular eyeglasses that have linear polarizing lenses to be employed by a golfer to examine the surface of a putting green as an aid in deciding the speed and direction for a putting stroke. The planes of maximum transmission for the lenses are preferably complementary each lens 45° to horizontal. The polarizing lenses are supported to permit the golfer to rotate the lenses to a “tip-up” position out of the line of sight, which enables the golfer to alternatively see a direct view and a polarizer altered view of the putting surface without significant delay of play.
