Do We Have a Dominant Eye?

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 also have a dominant eye.

A dominant eye isn’t always about one having better vision, but rather one leading better than the other because of preference. 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 is right-handed is more likely to be right-eye dominant, but it is possible to be right-handed and left-eye dominant.

Eye dominance can vary from person to person. One person may have strong degree of dominance in one eye, while another person may have an eye with a lesser difference in dominance from the other eye.
