The role of ocular dominance in processing visual memory and analytic tasks is unknown. Research has variably showed both significant effects and no effect of ocular dominance on visual perception, motor control, and sports performance. The goal of this study was to determine if there is a relationship between ocular dominance and visual processing under a variety of computer gaming tasks. This was accomplished by first determining subjects’ ocular dominance through the Miles test, and then examining the subjects’ visual performance on four different Lumosity games under three conditions: left eye, right eye, and both eyes. Results suggest a relationship between ocular dominance and score in the simplest game used, named Raindrops, but did not identify a relationship between ocular dominance and accuracy. The study did not suggest a relationship within any of the other games that measure a variety of different abilities. It is possible a relationship between ocular dominance and score in the game Raindrops may have been due to the simplicity of the task. A small sample size (n = 20) may have also contributed to the inability to detect significant effects. Future studies incorporating larger sample sizes might focus on ocular dominance as it relates to simple arithmetic tasks.
