Pengaruh Pergeseran Pupil Distance Terhadap Tajam Penglihatan Pada Masasiswa ARO Leprindo Jakarta Tahun 2025

Abstract

This study examines the effect of pupil distance (PD) shifts on visual acuity among 52 ARO Leprindo Jakarta students with refractive errors. A mismatch between the optical center (OC) of spectacle lenses and the wearer’s PD may induce a prismatic effect that reduces visual performance. Data were obtained using a pupilometer, phoropter, and Snellen chart, and analyzed with Kolmogorov–Smirnov, Levene’s test, and Paired Sample t-test. Results showed that before the PD shift, 98.1% of participants had normal visual acuity (mean 0.9962). After the PD was shifted within tolerance limits, visual acuity decreased significantly, with 50% falling below 20/20 and a mean of 0.8973. Statistical tests confirmed significant differences (p=0.000) and a weak positive correlation (r=0.318, p=0.022). These findings indicate that even small PD shifts can impair visual acuity, highlighting the importance of accurate PD measurement in optometric practice.
