Accessory used to mfr. visual aids for golfers with sight problems

摘要

The accessory consists of a spectacle frame, with semi- circular supports (22) for a number of lenses. An angular scale (6) is mounted on the front of the supports. The test lenses, which are mounted in the supports have handles with which they can be rotated. The test lenses establish the degree to which the golfer is short- or far-sighted and also check if there is any deviation between the angle observed between the head of the golfer and the line to the target.
