Eye teaming, or Binocular vision, is the ability of both eyes to work together. Each of your eyes sees a slightly different image and your brain, by a process called fusion, blends these two images into one three-dimensional picture. Good eye coordination keeps the eyes in proper alignment. A common eye-teaming problem occurs when the eyes have a “tendency” to turn in, out, up, or down and the ability to compensate for this tendency is inadequate. Poor eye coordination results from a lack of adequate vision development or improperly developed eye muscle control. Although rare, an injury or disease can cause poor eye coordination.
Some signs and symptoms associated with a Binocular vision problems may include the following:
- Eye strain
- Double vision
- Reduced reading efficiency
- Loss of place when reading
- Decreased reading comprehension
- Motion sickness when reading in a moving vehicle
- Inability to appreciate 3D movies
- Avoidance of a visually demanding tasks
Children with binocular vision dysfunction are more likely to show a very short attention span at desk work and may attempt to compensate by covering or closing one eye when reading and reading very slowly or re-reading everything so they can understand what they read. Poor binocular vision may also inhibit athletic performance in sports that require accurate depth perception, including basketball, baseball, and tennis.
