Your Dominant Eye and Why it Matters

24 Jul 2013

You’ll often see the term ‘dominant eye’ when reading about near-vision correction-so what does it mean?

What exactly is ocular dominance?

Wherever in the body there are two organs carrying out the same function, it is likely that one can be considered more dominant than the other. For instance, people can be left-handed or right-handed; and when it comes to your eyes, the right eye is commonly more dominant than the left, meaning it works harder and sends more visual messages to the brain.

Is there a link between being right handed and having a dominant right eye?

There is no link between handedness and ocular dominance, so if you are right handed and have a dominant right eye, it is merely a coincidence.

I can see fine with either eye, does this mean I don’t have a dominant eye?

Only a very small percentage of people have balanced ocular function, with over two thirds of the population having a dominant right eye. When you look into the distance using both eyes together, the vision of the dominant eye automatically compensates for the shortcomings of the non-dominant eye. The non-dominant eye takes a back seat and lets the dominant eye do most of the work.

How do I tell which eye is dominant?

A very simple test can be done at home to determine which eye is physically stronger.

  • Using the trigger finger motion, extend your hand at arm’s length with both eyes open and the line of vision from your index finger aligned with a clear marker in the background
  • Once you have pinpointed your gaze onto the direct centre of your target, close one eye.
  • If your extended index finger remains aligned with the target, then you are using your dominant eye.
  • If the marker has moved and is no longer aligned with your finger point, you are using your non-dominant eye.
Does eye dominance weaken with age?

As you age, you may have noticed changes occurring in your vision capability, especially after you turned 40. The most common complaint is trouble reading near objects as they appear blurry and out of focus. The medical term for this condition is presbyopia and it is the completely natural effect of your eyes ageing.

I don’t want to wear reading glasses so what can I do for presbyopia?

If reading glasses don’t fit into your lifestyle, then the KAMRA inlay may be for you. Only available at Optilase clinics across Northern Ireland, this breakthrough technology corrects presbyopia permanently by utilizing the non-dominant eye.

How does my non-dominant eye come into play with KAMRA technology?

The KAMRA inlay is a simple procedure that sees an incredibly small lens implanted into the cornea of the non-dominant eye to help correctly focus light that enters the eye. This corrects near vision while the dominant eye remains untouched and continues to work on distance vision. Combined, both eyes carry out natural vision function in harmony together.
