So, if you have a glasses prescription and know which eye is weaker and which is stronger, it might not necessarily be reflected in the dominance. Knowing which eye is your dominant one can also help you to optimise your head position for other sports like shooting or archery.Īs we mentioned before, your dominant eye isn’t always the one with the best visual acuity. This is because your brain processes the images more powerfully from the side of action, giving you a slight edge. left handed with a dominant right eye or vice versa) is best for sports with side on stances such as baseball, cricket and golf. In sports, it’s thought that “cross dominance” (e.g. This means that there is no direct connection between which hand we use and which eye is our dominant one. The right brain hemisphere controls the left hand and is responsible for creativity and imagination. When it comes to our vision, both brain hemispheres control both eyes but “ each one takes charge of a different half of the field of vision, and therefore a different half of both retinas”.

Our right hand is controlled by the left side of the brain, responsible for speech, writing and communication. The brain is made up of two hemispheres, the left and right. Research shows that right handed people are more likely to have a dominant right eye (up to 2.5 times more likely), but right handedness can also come with left eye dominance, and vice versa. However, only 67% of the population have a dominant right eye so, contrary to popular belief, handedness and eyedness don’t always match, and you cannot use one to predict the other accurately. Some individuals have one eye which is just slightly dominant, while others have one eye which is highly dominant over the other – leading to a range of visual issues which we’ll discuss later in this piece.Įveryone has a preferred hand in life and for, 90% of the population, that’s usually the right hand. It is also suggested that there is a spectrum of eye dominance among different people. This phenomenon is called mixed ocular dominance. All About Vision suggests that, if it appears there is no dominance at all, then it’s likely that each eye is dominant for particular visual tasks, taking it in turns to function more powerfully. The dominant eye simply has more neural connections to the brain than the non-dominant eye.Īlmost everyone has a dominant eye, even if the difference between the two eyes doesn’t feel that stark. It’s this preference which determines the eyes’ dominance, not the visual acuity of each eye. It’s made up of bands of neurons which respond preferentially to input from one eye or the other. The cortex is responsible for processing visual information. Essentially, it just means that this particular eye relays information more accurately to your brain’s visual cortex than the other eye.

Contrary to popular belief, your dominant eye doesn’t always have better vision than your non-dominant eye. At some point in your life, you’ve probably heard someone referring to a “dominant eye”, whether that’s in a sporting setting, optician’s context, or another situation entirely.
