Abstract

Purpose: The aim of this study was to investigate eye dominance and reading performance based on eye movements and reading speed. Methods: The eye dominance of 30 subjects was determined using the sighting test (hole formed by hands). The subjects were asked to read the numerical reading material aloud in English from left to right and from right to left at random. The number of saccades, regressions, and inter-fixations per minute was calculated using Visual-Oculography (VOG) and the reading speed was recorded as number of characters per minute using stopwatch. Results: No significant differences in reading speed among right and left eye dominant subjects as they read from left to right and right to left directions (p>0.05). However, left eye dominant subjects were found to read significantly faster compared to right eye dominant subjects in both directions of reading (p<0.05). In term of eye movement patterns, no significant differences in saccades, regressions, and inter-fixations per minute were found between subjects with right eye dominance and left eye dominance for both reading directions (p>0.05). Conclusions: Reading performance in term of eye movement and speed was not affected by eye dominance, but subjects with left eye dominance read faster than subjects with right eye dominance.
