Abstract
Objective: To compare visual field (VF) parameters and pupil size as measured through colored and clear contact lenses (CL) in Asian population. Materials and Methods: Demographic data and CL prescription data were recorded during the baseline visit. Visual acuity and autorefraction were evaluated while patients wore clear CL, followed by slit-lamp examination and intraocular pressure measurements after CL removal. During the second visit, subjects were given dark browncolored CL with their same prescription. Visual acuity and autorefraction were measured. Pupil size and VF tests were measured twice with the clear CL and the colored CL. Measurements through colored and clear CL were compared. Results: Twenty-one volunteers (mean age: 31 years) were recruited. Refractive error varied from 0.00 to -7.00 diopters. Mean horizontal meridian measured through clear and colored CL was 134.8±7.8° and 133.3±4.7°, respectively. Mean vertical meridian measured through clear and colored CL was 100.1±3.8° and 100.4±2.5°. Mean total VF area measured through clear and colored contact lenses was 9,890.9±822.8° and 9,882.7±528.1°. There was no significant difference between clear and colored CL groups for horizontal meridian, vertical meridian, total VF area, or pupil size. Conclusion: There was no significant difference in any evaluated parameters between clear and colored CL
