The spectacles include spectacle lenses (12) through which light can pass to the eyes of the golfer and image generation and projection means (26, 30), carried by the spectacles, arranged to project, typically onto one eye only, an image which will be visible to the golfer and which is superimposed on his normal field of view through the spectacle lenses. The image includes a series of lines (50, 52, 53) at least a first (50.1, 50.2) of which extends from side to side as viewed by the golfer and at least a second (52) of which extends in a direction normal to the first line. |
