The Critical Importance of Binocular Vision

So what if you have healthy eyes that can see small details to 20/20 or better, even with the help of proper lens correction? Is that all there is to have good vision?

Well, don’t forget, you have two eyes, and they are supposed to work together as a highly coordinated team. The ability to look with both eyes in all directions, far and near, with synchronized paired accuracy without wandering in or out, or up or down is a function of the human brain not found in any other function of human physiology or sensory processing. This is referred to as binocular vision, which can be defined as:

The visual process of automatic and precise coordination of the two eyes such that the separate image from each eye is simultaneously fused in the brain into a single perception of the world that includes the ability to accurately perceive depth, otherwise known as “depth perception.” 

When binocular vision problems occur, the result can have a tremendous impact on the individual.

In young children, when binocular vision problems are not detected in infancy or toddlerhood, a condition known as Amblyopia (Lazy Eye) occurs, resulting in a loss of vision of visual acuity and poor or no depth perception. This can be due to binocular vision failure, such as a crossed eye or turned eye known as Strabismus and/or anisometropia, when one eye has a significant difference in the refractive state, such as farsightedness, nearsightedness, or astigmatism vs. the other eye. 

Other common forms of binocular vision problems typically occur in children, but are found in adults too, can result in overlapping/doubling of words causing reading problems, attention/concentration problems, and difficulty with overall academic or work performance, especially when reading or on screens. These are known as non-strabismic binocular problems such as Convergence Insufficiency.

Binocular vision problems are also commonly found in those who have had a traumatic brain injury (TBI) or concussion (mTBI). This can result in chronic double vision, balance issues, and vertigo-type symptoms.

The important thing to know for those who suffer from binocular vision problems, safe and effective treatment is readily available. At Wow Vision Therapy, we help children and adults develop their binocular vision so that they can enjoy the benefits of seeing the world with two eyes working together as an effective and coordinated team. This is because two eyes working well together are better than one. Thus, life takes binocular vision!
