Purpose : The purpose of this study was to compare the difference in the visual acuity of dominant eye and non-dominant eye according to the degree of contrast.
Methods : The dominant eye of 60 adults (22.4±2.2 years) who had no ophthalmologic disease was determined using the Hole-in-the-card method. The differences between dominant eye and nondominant eye were compared with high contrast visual acuity and low contrast visual acuity.
Results : The mean of high-contrast visual acuity (contrast ratio 100%) of the subject was 0.07±0.05 logMAR, 0.11±0.13 logMAR, and the mean of low contrast visual acuity (contrast ratio 10%) was 0.31±0.09 logMAR, and 0.27±0.08 logMAR (p=0.049), respectively. The dominant eye was measured greater than non-dominant eye in high-contrast visual acuity and non-dominant eye was measured greater than dominant eye in low-contrast visual acuity (p=0.003). The visual acuity difference of 0.16±0.23 logMAR when the visual acuity in the same direction is excellently measured in the high contrast chart and the low contrast chart, and the difference in visual acuity of 0.05±0.00 logMAR when the visual acuity in the change direction.
Conclusion : The dominant eye greater than non-dominant eye in high contrast visual acuity but low contrast visual acuity can be effected by the difference of binocular visual acuity in high contrast. Therefore, it should be considered according to the purpose of environment and vision life at the correction.
