This episode  examines the validity of eye dominance testing in sports. It argues that unlike hand dominance, eye dominance lacks clear scientific support, as different tests yield inconsistent results and studies show no correlation between eye dominance and athletic performance in sports requiring binocular vision. The episode critiques existing eye dominance tests, highlighting their flaws and suggesting that eye preference, not dominance, might be a more accurate concept. We conclude that focusing on utilizing both eyes optimally is crucial for most sports, rather than determining a dominant eye. While acknowledging the potential relevance of eye dominance in sports like archery, the episode highlights  the need for accurate testing and a nuanced understanding of visual needs specific to each sport.
