Patrick Mouratoglou often points to a detail most players never think about: your dominant eye. Just as you have a stronger hand, your brain leans on one eye to judge where the ball is and when to hit it.
Understanding your dominant eye — and turning your head so it leads toward the ball — can make the ball easier to track and your timing more reliable. Here is what it means and how to use it.
What is the dominant eye?
One eye is naturally dominant: the brain trusts it more for aiming and depth. It is not about which eye sees better, but which one leads. Most people are right-eye dominant, but plenty are left-eye dominant, and some are cross-dominant — their dominant eye is on the opposite side of their dominant hand.
Why it matters in tennis
Tennis is a tracking sport — you judge a small, fast ball in three dimensions. When your dominant eye has a clear line to the ball, you read its flight and contact point better. It matters most where vision is hardest: watching the toss on the serve, reading a fast ball at the net, and turning sideways for groundstrokes, where your head position decides which eye leads.
Find your dominant eye
Use the triangle test. Stretch both arms out, overlap your hands to make a small triangle, and centre a distant object in the hole with both eyes open. Now close one eye, then the other. The eye that keeps the object inside the triangle is your dominant eye.
Mouratoglou breaks the idea down in this short:
What Mouratoglou emphasises
In his explanations, Mouratoglou stresses turning the head so the dominant eye faces the ball instead of leaving the head square. A small head turn gives your leading eye a clean view through contact, and keeping the head still at contact — eyes on the ball — stops the common habit of pulling off the shot too early. On the serve that means keeping your eyes up on the toss a fraction longer.

How to use it as a beginner
As a beginner, do not overthink it: find your dominant eye, then on each shot turn your head a touch so that eye tracks the ball, and keep your head still through contact. On the serve, watch the ball all the way to the strings. It is a small adjustment that quietly improves timing and consistency.

Test your dominant eye while playing tennis
- Use the triangle test to find out which eye is dominant.
- Film yourself from the side during a series of relaxed forehands.
- Check whether you keep tracking the ball all the way to contact.
- Repeat this with your backhand.
- Only try a small change in head position under guidance or deliberately during a drill.
- Compare the comfort and quality of your strokes.
Frequently asked questions
Does everyone have a dominant eye?
Almost everyone does — the brain naturally favours one eye for aiming and depth. A small number of people have no strong dominance.
What if I am cross-dominant?
It is common and not a problem. Your dominant eye is simply on the opposite side of your dominant hand, which makes the head-turn to let that eye lead the ball even more useful.
Can I change my dominant eye?
You cannot really switch it, but you can learn to position your head so your dominant eye gets a clear line to the ball — which is the whole point.
Is this only for tennis?
No — eye dominance helps in any ball or aiming sport, but it is especially noticeable in fast tracking sports like tennis.
