Examining the concordance between dominant eye and hand preference in healthy adults

Abstract

Aim: This study was designed to reveal the relationship between dominant hand and dominant eye and to present the dominance rates of the population. Methods: 160 healthy subjects (80 females, 80 males) between the ages of 18-60 were included in the study. While the determination of the dominant hand was based on the answers of the participants, the Dolman test was used to determine the dominant eye. The chi-squared test was used to determine the relationship between the variables. Results: Of the sample, 91.3% (146 subjects) predominantly used their right hand and 68.8% (110 subjects) used their right eye. The right eye and hand were dominant in 106 subjects, and the left eye and hand were dominant in 10 subjects. As a result of the chi-square test, there was a statistically significant difference between the dominant hand and the eye. Conclusion: Since the right hand and right eye were highly dominant in the study, it is thought that the left hemisphere of the participants was dominant in terms of functional lateralization. Additionally, it is thought that the repetition of the study in patients with presbyopic cases and in patients before cataract surgery will be clinically beneficial.
