Dominant Eye: Here’s Looking at You

Just like we use one side of our body more than the other and have a dominant hand that we use for writing, most of us have a dominant eye. A dominant eye isn’t always about one having better vision. Your dominant eye is the one that provides slightly more input to the visual cortex of your brain and relays information more accurately — such as the location of objects. Research shows that eye dominance and handedness are associated, though not directly related. Someone who’s right-handed is more likely to be right-eye dominant, but it’s possible to be right-handed and left-eye dominant. Eye dominance can vary from person to person, with one person having a strong dominance, while another has a lesser dominance or no dominance at all. Knowing which eye is your dominant eye can improve your performance in certain sports and activities, such as photography. Your dominant eye plays a vital role in shooting and hitting moving targets, so if you find you’re having trouble hitting moving targets, you could benefit from a test to find your dominant eye. Eye dominance doesn’t have any medical significance if you’re not experiencing vision problems.
