Abstract

This study is conducted to investigate the effect of contrast polarity towards eye fixation patterns when reading text on a smartphone in bright and dark conditions involving the effects when reading on a smartphone such as in real-life situations. The number of fixations and duration of fixation showed no statistically significant difference (p=0.160 and 0.099 respectively). However, emmetropic subjects showed a higher result in bright conditions compared to myopic subjects (p=0.046). This concludes that emmetropic eye movement efficiency seems superior, possibly due to lower spherical order aberration as pupil size decreases in bright illumination.
