Bifocal and Multifocal Contact Lenses for Presbyopia and Myopia Control

Table 4

Summary of results of recent studies evaluating stereoacuity with different methods in presbyopic patients wearing simultaneous image multifocal and bifocal soft contact lenses. The unit of stereoacuity is seconds of arc (arcsec).
