ABSTRACT:
An optical apparatus for training a golfer which is the form of a pair of spectacles with tinted lenses, one of which is inclined so that an image projected onto an inner surface of the lens is reflected onto an eye of a user. The image comprises data which aids the golfer in a training stroke. To reduce ghost images, to allow for binocular vision and to superimpose the projected image on a background view, the lenses have an absorption of from 60% to 85%.
