How to Find Your Dominant Eye

Do you know your dominant eye? Is it even possible to have a dominant eye? We are sure you have heard the term ‘dominant eye’ but you might not be sure what it means. Please allow me to explain.

What is a dominant eye?

Simply put, your dominant eye is the one that provides more input to the visual part of the brain and relays information more accurately, especially with regard to the location of objects.

Sometimes the dominant eye is used to describe the normally functioning eye in cases where the other is weaker such as with strabismus (eye turns) and amblyopia (lazy eye).

How to do a Dominant Eye Test

Here is a simple test to determine your dominant eye.

  • Create a small triangular opening between your thumbs and forefingers to form 45 degrees by placing your hands together as shown below.

  • With both eyes open, center triangle on an object at some distance from you-such as a door knob.

  • Close your right eye.

  • If the object remains centered, then the open eye (the left one) is your dominant eye. If the object moves, then your right eye is the dominant eye.

Is Eye Dominance Directly Related to Handedness?

Studies have shown that being right-handed/left-handed is not directly related to eye dominance but with both the right side tends to be the dominant

Research shows that around 90% of the human population are right handed and 67% are right-eye dominant.

While it is correct to say that a right-handed person is 2.5 times more likely to be right-eye dominant, it’s still impossible to determine eye dominance based on your dominant hand.

No Dominant Eye: Is It Possible?

It’s nearly impossible to not have a dominant eye but there are a few specific cases.

If an individual lacks a dominant eye, it’s more likely that the person has a mixed ocular dominance (alternating ocular dominance), where one eye is dominant for certain tasks and the other eye is dominant at different times.

Fact: Knowing your dominant eye will help you in photography and in sports like golf and baseball.
