Contact lenses for athletes.

The introduction and development of soft lenses and rigid gas-permeable lenses has ushered in a new era in fitting athletes with contact lenses. Many of the well-known disadvantages associated with polymethylmethacrylate (PMMA)-type lenses have been either eliminated or minimized. Fitting athletes with contact lenses must still be viewed with caution, however, since athletes' visual needs are usually much more demanding than those of the general public. An indiscriminate choice of lens design can adversely affect athletic performance and may even create a hazardous situation. An intelligent choice of lens can provide some subtle advantages that may improve athletic performance and provide the margin for victory.
