Contrast sensitivitya functions (i.e. minimum contrast required to resolve a sine wave grating as a function of spatial frequency) were determined for subjects when wearing normal spectacle corrections and when wearing either hard or soft contact lenses. Comparison of results for spectacle correction and contact lens corrections provides a more definitive evaluation of visual performance with contact lenses than do the conventional clinical procedures.
