What Is A Dominant Eye? How Can You Tell Which Eye Is Dominant?

At Fraser Valley Cataract & Laser, we know that the dominant eye is the eye that exerts more effort and transmits a greater number of visual signals to the brain.

The Best Way to Find Your Dominant Eye

It is quite easy to determine which eye is dominant by using sighting tests. At FVCL, we have our patients follow the steps below:

1. Extend your arms in front of you, palms facing outwards. Create a small triangular opening between your thumbs and pointer fingers.

2. With both of your eyes open, center this triangle on a distant object, creating a picture frame around it. The opening should not be much bigger than the object in view.

3. Close your left eye. Once closed, do not move your hands.

4. If the object stays centered when your left eye is closed, then your right eye (the eye that is open) is your dominant eye. If the object is no longer framed by the triangular opening, your left eye is your dominant eye.

In most cases, this will allow you to accurately identify your dominant eye. If you are having a difficult time identifying your dominant eye through this test, please reach out to your vision counselor at FVCL.

Not Everyone Has A Dominant Eye

Although uncommon, it is possible for individuals not to possess a dominant eye. The level of dominance can vary among people, with some having a highly dominant eye, and others experiencing less of a difference between their eyes. 

Eye Dominance and Hand Dominance Can Be Associated

Eye dominance and handedness are not directly related, but they are significantly associated. Population studies have shown that about 90% of people are right-handed, and about 67% of right-handed people are right-eye dominant. Despite this research, it is impossible to predict eye dominance based on handedness alone.

Why Is it Important to Know Which Eye Is Dominant?

Your dominant eye is the eye that your brain naturally prioritizes. It is the eye that your brain relies on to receive accurate positional information. This is particularly important in activities that demand precision and aim.

Using your dominant eye can help you perform better in activities such as:


Proper alignment is important in sports like baseball, softball and golf. It is good to take full advantage of your dominant eye when playing these sports. To achieve your best hits, keep your dominant eye on the ball.


Look through the viewfinder with your dominant eye to have a more accurate preview of the shot. If you use your non-dominant eye, certain details you thought you were capturing can be displayed slightly off or completely out of the frame.


Improve your shooting accuracy by knowing your dominant eye. Good eye and hand coordination is necessary to be successful at hunting. The dominant eye is the eye that looks directly at an object, which is a crucial factor for accurate shooting. You should shoot left-handed if you have a dominant left eye, and right-handed if you have a dominant right eye.
