How to Find Your Dominant Eye

Published by Lance Kugler, MD on September 18, 2017

At Kugler Vision in Omaha, we know that your dominant eye is the eye that works harder and sends more visual messages to your brain. Typically, the terms “dominant eye” or “ocular dominance” are used to describe the normal vision condition in which both eyes function together and have a relatively equal visual acuity, with one eye as the leading eye.

Two Ways to Find Your Dominant Eye

It’s pretty easy to determine which eye is dominant by using sighting tests. At Kugler Vision, we have our patients follow the steps below:

  1. Extend your arms in front of you and create a triangular opening between your thumbs and pointer fingers by placing them together.
  2. With both of your eyes open, center this triangle on a distant object, like a clock or picture frame.
  3. Close your left eye.
  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.

Here is another simple way to find your dominant eye:

  1. Keep both eyes open and focused on a distant object, then extend your arm out and point with your index finger or thumb at the object.
  2. Alternately close one eye at a time
  3. The eye that keeps your finger directly in front of the object while the other eye is closed is your dominant eye.

In most cases, these two sighting tests will accurately identify your dominant eye. If you are having a difficult time identifying your dominant eye through these tests, please contact Kugler Vision to schedule an EyeAnalysisTM eye exam.  

Not Everyone Has A Dominant Eye

It is possible to not have a dominant eye, but it is very uncommon. Some people may have one eye that is very dominant, while others may have less of a difference in the dominance of their two eyes.

Eye Dominance and Hand Dominance Aren’t Necessarily Linked

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

It Is Important to Know Which Eye Is Dominant

Your dominant eye is the eye that your brain is wired to favor. In other words, your dominant eye is the one that is primarily relied on for precise positional information, which is especially important in activities that require aim.

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

  • Hunting – improve your shooting accuracy by knowing your dominant eye. Good eye and hand coordination is necessary to be successful. The dominant eye is the eye that looks directly at an object, a crucial factor for accurate shooting. You should shoot left-handed if you have a strong left eye and right-handed if you have a strong right eye.
  • Photography – 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.
  • Playing sports – proper alignment is important in sports like baseball, softball, darts, and golf. It’s good to take full advantage of your dominant eye when playing these sports to achieve your best hits by keeping your dominant eye on the ball.

I don’t have a dominant eye. When I do these tests, I see two sets of hands — anything I’m not focusing on is double and semi-transparent.

I’m rather happy with this rare skill. I’ve never met anyone else who perceives the world the way I do!

Many people are not strongly dominant in one eye or the other, so it’s possible.
Thanks for reading the blog! Glad you enjoyed the content.

I am the same. I am a new archer and I find it really frustrating when no one believes hat I see two arrows or two targets if I keep both eyes open. I have to shut my left eye to force 100% dominance in my ight eye otherwise it is really distracting. It took a while to realise that equal eye dominance was real as u couldn’t understand how everyone else coukd only see one arrow or target.

I’m there same way. No dominant eye. I have to close one eye in order to aim!


When I do the triangle test and try to have the object centered, when I close my right eye it is it is to the left and when I close my left eye it is to the eight equally. I can’t hit a target.


When I first started using a photo camera at age 5, I found it difficult to decide which eye to use. I ended up going with my left eye, which I use for photography to this day. I do find it easier to shut my right eye. Perhaps I’m right eyelid dominant? Whenever I try the hand tests, I don’t get a consistent result. And as others have mentioned, I do have to shut one eye when aiming, otherwise I see double.


I am the same too. When I focus my eye on a distant object and try to put my finger on top of the object, I just can’t, because I see two fingers. So I just tend to center the object in between my two “visual” fingers.
