- Frequently Asked Questions (FAQ’s)
Our eyes are the windows to the world, granting us access to a rich tapestry of colors, shapes, and dimensions. But did you know that each of us has a dominant eye, one that our brain prefers over the other when processing visual information?
Eye dominance, also known as ocular dominance, is the tendency to prefer visual input from one eye over the other. It is important to understand eye dominance when using binoculars because it affects the quality of the image you see.
In this article, we will discuss eye dominance, how to determine which eye is dominant, and its impact on binocular usage.
What is Eye Dominance?
Eye dominance is the tendency to prefer visual input from one eye over the other. It is somewhat analogous to the laterality of right- or left-handedness, but the side of the dominant eye and the dominant hand do not always match.
This is because both 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.
How to Determine Eye Dominance?
There are several ways to determine eye dominance.
- One way is to use the Porta test. Extend one arm in front of you and, with both eyes open, align your thumb or index finger with a distant object. Alternate closing each eye, and the eye that remains aligned with the object is your dominant eye.
- Another way is to use the Miles test. Extend your arms in front of you and create a triangular opening between your thumbs and pointer fingers by placing them together. With both of your eyes open, center this triangle on a distant object, like a clock or picture frame. Close your left eye. If the object stays centered, then your right eye is your dominant eye. If the object moves, then your left eye is your dominant eye.
Impact of Eye Dominance on Binocular Usage
Eye dominance can impact the quality of the image you see through binoculars. Your dominant eye may see a dark halo around the image if the ocular lenses of the binoculars don’t line up perfectly, resulting in an unsatisfactory view. It is important to adjust the binoculars to your dominant eye to avoid these issues.
Eye Dominance: A Fascinating World
Eye dominance, a captivating aspect of human vision, refers to the predisposition of the brain to rely more heavily on input from one eye than the other.
While both eyes work in harmony to form a coherent picture of the world, the dominant eye takes center stage, playing a vital role in how we perceive depth, distance, and spatial relationships.
Unraveling the Brain’s Marvelous Dance
At the core of eye dominance lies the intricate dance of the brain’s visual cortex, where visual information from each eye converges. Discovering how the brain’s hemispheres come into play, and the development of eye dominance in infants and young children, provides us with profound insights into our visual sense.
The Dual Nature of Dominance
Understanding the advantages and disadvantages of having a dominant eye is crucial in comprehending the nuances of binocular vision. Enhanced visual acuity and hand-eye coordination come hand in hand with potential challenges in tasks that require input from both eyes.
Binocular Vision: Merging Realities
Binocular vision is the symphony where our dominant eye collaborates with its counterpart to create a vivid 3D experience.
The fusion of images and the marvel of stereopsis lie at the heart of this wondrous process, enabling us to judge distances, catch fast-moving objects, and immerse ourselves in the world around us.
When Dominance Meets Compatibility:
The compatibility of our dominant eye with binocular vision is essential for seamless visual function. Yet, sometimes, our visual system faces conflicts that challenge our perception.
Vision Disorders and Eye Dominance:
Eye dominance can also intersect with vision disorders, such as amblyopia (lazy eye) and strabismus (crossed eyes). Understanding these connections allows for tailored treatments that take into account the dominant eye’s role in the healing process.

Understanding eye dominance and its impact on binocular usage is crucial for getting the best viewing experience. It is important to determine which eye is dominant and adjust the binoculars accordingly to avoid issues with the quality of the image you see.
When buying binoculars, it is recommended to check if the binoculars have an IPD adjustment mechanism and if they cater for differences in eye dominance. This will help you get the best viewing experience possible.
