Purpose: This study was to compare the contrast sensitivity evaluated the visual ability at near wearing functional lenses for pre-presbyopes altered their single vision lenses to functional progressive addition lenses with low addition for 2 months. Methods: Healthy 32 subjects aged 24.03${pm}$1.87 (male 23, female 9) who were recruited from university students wore functional progressive addition lenses(EYE-T, Chemilens Co., Korea, ADD 0.75D) for 2 months. Corrected visual acuity at distance and near and contrast sensitivity at near were tested right after wearing functional progressive addition lenses to compare wearing single vision lenses. And we had second test after 2 months later. Results: Comparing between test and retest, contrast sensitivity at near wearing functional progressive addition lenses was improved more than wearing single vision lenses at all spatial frequency of right, left and both eyes. Conclusions: There was considered that contrast sensitivity test is useful to evaluate the visual ability as well as quality of near work and can be applied variously.
