Like hands, people also have preference on which eye to use, mostly it is involuntary. This might come as a shock to many because it appears that both eyes are at work, when in fact only one is more focused than the other. This can go on for years without significant disadvantages, but for certain sports like archery, shooting, golf, darts, and anything that involves accuracy and dexterity.
As said earlier, if you are involved (or would want to be involved) in sports requiring targeting like archery, golf, and shooting, you may find it a little uncomfortable if you are right-hand dominant while being left-eye dominant. Take for example while on a shooting range, aiming using your right eye while being left-eye dominant and right-hand dominant will actually decrease your accuracy and reaction speed because your right eye is not used to doing those kind of things.
Another perfect example is for surgeons. Surgery requires precise hand movements, everything within a surgery requires the hands and eyes to be perfectly accurate. Don’t worry if you are having trouble with being one-eye dominant because it can be fixed (see below).
Simple Test to Find Your Ocular Dominance
There are several tests to find your eye dominance, here I will lay out the common and easiest one.
- Extend your arms in front of you
- Follow the image above
- Using the small opening on the web of your hands, try spotting a small object (a dot, your cat, light bulb, etc.)
- Close your left eye. If you can still see the object then you are right-eye dominant.
- Close your right eye. If you can still see the object then you are left-eye dominant.
If being one-eye dominant is a problem you’ve been experiencing for a long time, or you just want to get out of it, you can fix it by suppressing your dominant eye’s vision, thereby forcing your other eye to do the job and rewire your brain. A home-made eye patch will do or just simply close your dominant eye several minutes a day. You can also try leaning your less dominant eye towards the object you are looking at. If you’ll notice, your dominant eye is usually leaning towards the object you are looking, try changing that.
