?An Aid for Viewing a Golf Putting Green to Assist in Discerning the Subtle Variations in the Putting Surface,? Sound Good?

By David Dawsey PE Esq

ADVERTISEMENTS

An interesting patent issued on Tuesday that is supposed to assist golfer in reading greens. I reviewed the patent and thought to myself?.. ?I would give those glasses a try.? The patent is USPN 7370960 titled ?Method and Apparatus for Viewing a Golf Putting Green? and describes the invention as:

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 of a puffing stroke. The planes of maximum transmission for the lenses are preferably complementary each lens 45 degrees to horizontal. The polarizing lenses are supported to permit the golfer to rotate the lenses to "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.

The present invention utilizes a unique property of linear polarizers which are oriented with the maximum transmission angles at preferably 90 degrees thereby presenting two distinct images of the same scene to the right and left retinas. These non coherent images are processed by the eye-brain system to present an erect image that emphasizes the subtle surface differences which result from variations in the viewed surface that cannot be seen with the unaided eyes.
