Eye Dominance Test

This test identifies your dominant eye, which is important for activities like photography, sports, and vision therapy.

Your dominant eye is the one that provides slightly more input to the visual cortex and tends to be the one you instinctively use when looking through a viewfinder or aiming.

1 Preparation

You'll need to perform a simple physical test where you'll look at a target through a triangular opening in your hands.

Make sure you're about 3-4 feet (1 meter) away from your screen.

2 Create a Triangle

Stretch your arms out in front of you and form a small triangle (about 1 inch/2.5 cm per side) between your thumbs and index fingers.

3 Focus on the Target

With both eyes open, center the triangle on the target below.

Keep focusing on the red dot through the triangle.

4 Close Each Eye

While keeping your hands steady, alternately close each eye:

The eye that keeps the target centered in the triangle is your dominant eye.

Which eye kept the target centered?

Your Eye Dominance Results

Your dominant eye is: Right

How to use this information:

Photography: Use your dominant eye when looking through the viewfinder
Sports: Align your dominant eye when aiming (archery, shooting, golf)
Vision Therapy: Helps professionals design corrective exercises
Daily Life: Your brain relies more on this eye for spatial tasks

Note: About 70% of people are right-eye dominant, 20% left-eye dominant, and 10% have no strong dominance.
