Eye preference in human subjects : Consistency across measures and correlation with handedness
2010
Bengtsson, Therése
The aim of the present study was to determine the distributions of and correlations between hand preference, visual acuity and eye preference through a series of tests in 50 males 50 females aged between 17 and 39 years. Handedness was determined through the Edinburgh handedness inventory questionnaire. The handedness distribution was: right-handed 90%, left-handed 1 %, and ambidextrous 9%. I found that 30 % had better visual acuity with their right eye, 39 % had better visual acuity with their left eye, and 31% had the same visual acuity with both eyes. 75.2% on average used their right eye in the battery of tests and 24.8% on average used their left eye. There were no statistically significant differences between the sexes or age groups with any of the measures. No correlation was found between eye preference and visual acuity or eye preference and hand preference among all subjects. No statistically significance between the sexes was found.
