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
  • Headaches
  • 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
  • Incoordination/clumsiness

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.
