Purpose: On this study, we compared the relationship of dynamic stereoacuity according to the dominant eye, degree of dominant eye, and dominant agreement eye and hand.
Methods: For 130 adults (male 70, female 60), mean age of 21.06±2.21 years old, dominant eye, degree of dominant eye were measured by objective examination by using the diameter 3.8 cm × 3.8 cm thin ring, the dynamic stereoacuity were measured by three-rods test (iNT, Korea).
Results: Dynamic stereoacuity according to the dominant eye was center dominant eye without dominance was 14.97±13.80 sec of arc, right eye 22.10±20.01 sec of arc, left eye 22.31±20.39 sec of arc. Dynamic stereoacuity was better when there was no dominance, but the correlation of the dominant eye with dynamic stereoacuity was very low. When Dynamic
stereoacuity was separated by in the Center, Mild, Strong, dynamic stereoacuity was 14.97±13.80 sec of arc, 20.76±15.73 sec of arc and 24.45±25.60 sec of arc respectively. The dynamic stereoacuity results were worse when dominance was stonger. However dynamic stereoacuity was better than Center when the degree of dominant eye was rather strong in the dominant left eye. Dynamic stereoacuity according to the dominant eye and hand showed that right eye and hand was 22.63±20.54 sec of arc, left eye and hand was 17.36±10.13 sec of arc, right eye and left hand was 14.79±7.05 sec of arc,
left eye and right hand was 22.97±21.42 sec of arc so dynamic stereoacuity was comparatively good when the dominant
hand was left.
Conculsions: Correlation between the dynamic stereoacuity according to the dominant eye, degree of dominant eye was low, however when degree of dominant eye was Center 14.97 sec of arc, Strong 24.45 sec of arc, the dynamic stereoacuity tended to worse when degree of dominant eye was strong. As a result, dominant eye, degree of dominant eye would have to be considered in a more comfortable binocular balance between prescribed for the wearer in
binocular vision correction in binocular function such stereoacuity, sports vision training, presbyopia correction and mono vision.
