Purpose : In this study, three of the various dominant eye test methods such as +2.00D test, circular hole card test and eyepiece approach test were identified, and the correspondence between the dominant eye and other factors, the dominant hand and the corrective refractive power of both eyes was investigated.
Methods : Fifty eight adults (36 males and 22 females) age 23.79±5.03 years with no experience of general disease, eye disease and refractive surgery were participated. After full correction, a +2.00 D lens test, a hole in the card test and an eyepiece approach test were performed.
Results : The number of those with sensory dominant eye was 38 people on the right and 20 people on the left, sighting dominant eye was is 45 people on the right and 13 people on the left, and eyepiece dominant eye was 46 people on the right and 12 people on the left, showing that the ratio of right eye was high. The number of those with the dominant hand was 56 right-handed and 2 left-handed. Regarding agreement between dominant hand and dominant eye, it was revealed 38 sensory dominant eyes, 45 sighting dominant eyes and 44 eyepiece dominant eyes, showing that there was no statistically significant difference in the agreement between the dominant hand and eye(p>0.050). There was also no significant difference between the eyes corrected with low refractive errors and the dominant eye(p>0.050).
Conclusion : There was a significant difference between the direction of the sensory dominant eye and that of the visual dominant eye. Since the dominant eye was measured d differently depending on different measurement methods, it is considered that both a sensory dominant eye test and a visual dominant eye test should be performed for the dominant eye test.
