Abstract Purpose : The objective of this study was to investigate the influence of higher-order aberrations on contrast visual acuity among young adults. Methods : A total of 29 young adults in their 20s were recruited for this study. Contrast visual acuity and higher-order aberrations were measured. Based on the results of contrast visual acuity, a comparison was made between the higher-order aberrations at 100% and 10% contrast levels. Results : The average refractive error correction among the participants was –3.21±1.57 D. The measured values for higher-order aberrations, including defocus, oblique trefoil, vertical coma, horizontal coma, horizontal trefoil, oblique quadrafoil, spherical aberration, and horizontal quadrafoil were –0.326±0.730, -0.026±0.038, 0.042±0047, 0.023±0.048, 0.003±0.038, 0.000±0.022, 0.073±0.027, and 0008±0020 μm. The average high-contrast visual acuity and low-contrast visual acuity among the participants were 1.114±0.304 and 0.686±0.239 logMAR respectively. The analysis of the relationship between higher-order aberrations and contrast visual acuity revealed no significant correlation at high contrast (100%). However, at low contrast (10%), significant correlations were found between oblique trefoil and spherical aberration (p=0.009, p=0.039). Conclusion : Higher-order aberrations have an impact on contrast visual acuity in young adults. Correcting these higher-order aberrations may improve visual quality.
