Are you experiencing double vision or blurry vision and not sure why? You may be experiencing issues with your binocular vision, which is the ability to use both eyes together as a team. In this blog, we will discuss common issues related to binocular vision problems and how they can be detected.

What is binocular vision and why is it important?

Binocular vision is the ability to use both eyes together as a team. It allows us to perceive depth, see in 3D, and have better peripheral vision. When our binocular vision is functioning properly, our eyes work together seamlessly, allowing us to perceive the world around us clearly and accurately. However, when there are issues with binocular vision, it can cause problems with vision, such as double vision, blurred vision, and headaches.

Common Issues Related to Binocular Vision

  • Closing or covering one eye - This is often a sign that your binocular vision is interfering with your ability to perform a task.
  • Tilting or turning the head - Some people may find it easier to use both eyes together by tilting or turning their head.
  • Suppression - This is when the brain actively ignores or filters out some of the vision in one eye. This is often done unconsciously and is most common when reading or doing close tasks.
  • Convergence insufficiencyThis occurs when both eyes have difficulty pulling inward towards an object when looking at something close, especially for extended periods of time.
  • Convergence excess  - This occurs when the eyes cross in too far.

Detecting Binocular Vision Issues with a Brock Posture Board

One way to detect binocular vision issues is by using a Brock Posture Board. This is a quick and revealing way to probe for issues. The test is done by wearing red/green 3D glasses and placing a light behind a paper. If your eyes are working together as a team, you will be able to put the light precisely in the middle of a star. However, if you have convergence excess or insufficiency or other binocular vision problems, the light will be to the right or left of the star. This test can also help detect suppression, where the light may disappear in your vision.

Schedule a Binocular Vision Evaluation With Your Optometrist

Regular eye exams and vision screenings may not detect binocular vision issues.

Unfortunately, most regular eye exams include very little, if any, binocular vision testing. A standard vision screening at a school or doctor's office does not typically test for binocular vision problems.

Therefore, if you notice any behavior such as closing or covering one eye, tilting or turning your head, it is worth having a thorough binocular vision evaluation by our optometrist who specializes in this area. Many of these issues can be addressed with vision therapy, which is a program of eye exercises to improve your skills or ability to use both eyes together.
