This study seeks to quantify the near visual performance and subjective visual acceptance of toric contact lenses as compared to spherical lenses in an astigmatic cohort of patients. Primary Hypotheses: Subjects will have better near visual acuity and near visual performance with toric, as opposed to spherical, contact lens correction. As such, the following hypotheses will be tested: H01: There is no statistically significant difference in near visual acuity or near vision performance between contact lenses corrections Ha1: There is a statistically significant difference in visual acuity or vision performance between contact lenses corrections
