Purpose: On this study, we investigated the relationship between the kinetic visual acuity (KVA) and the dynamic stereoacuity and the effects of anisometropia with measuring KVA and the dynamic stereoacuity. Methods: For 63 adults (male 30, female 33), KVA and the dynamic stereoacuity were measured by using the kinetic visual acuity tester (KOWA AS-4A) and the Howard-Dolman test (H-D test) at distance 2.5 m after conducted full correction of subjects' refractive error respectly. Results: The means of KVA were $0.49{\pm}0.25$ for total subjects, $0.58{\pm}0.26$ for male, $0.40{\pm}0.22$ for female, and LogMAD (Log minimum angle of displacement) dynamic stereoacuities were $1.27{\pm}0.44$($28.44{\pm}25.03sec$ of arc) for total subjects, $1.28{\pm}0.44$($28.23{\pm}23.34sec$ of arc) for male, $1.27{\pm}0.45$($28.63{\pm}26.83sec$ of arc) for female. KVA showed a statistically significant difference between male and female (p=0.00), but dynamic stereoacuity was no significant difference (p=0.97). No significant correlation was present between KVA and dynamic stereoacuity (r=0.03). Also there were no significant differences in the dynamic stereoacuity of the three group which were classified according to the low, middle, high range of KVA (p=0.99). The anisometropia were less than 1 D and over 1 D when divided into two groups, KVA and dynamic stereoacuity showed no significant difference between each (p=0.11, p=0.99). There was no significant correlation between anisometropia and KVA (r=0.33), dynamic stereoacuity (r=0.18) but the correlation between KVA and anisometropia revealed more higer than between dynamic stereoacuity and anisometropia. Conculsions: The KVA for adults showed a significant difference between male and female and male was higher than female for KVA. The dynamic stereoacuity due to the KVA, the KVA and dynamic stereoacuity due to anisometropia were not significant differences between each and also were not great correlations.
