Binocular (Eye Teaming) Vision Disorders

Common Binocular Vision Disorders are Convergence Insufficiency and Convergence Excess. Both conditions are marked by poor eye teaming skills. Eye teaming is when the two eyes work together as a team to fuse the two different images coming from each eye into one single image. Proper eye teaming allows our eyes to engage in near tasks comfortably and provides us with a 3-dimensional awareness of our surroundings.

Difficulties using the two eyes together can cause either very noticeable problems (double vision, covering one eye), or much more subtle ones (drowsiness or fatigue in the classroom or when reading).  Eye teaming problems can affect both learning and athletics.  Some of the more common signs and symptoms of a binocular coordination problem are:

  • Double vision during reading or after looking up from reading, even if only for a few seconds
  • Covering one eye, especially when tired or reading
  • Winking when reading
  • Closing one eye in bright sunlight
  • Falling asleep when reading
  • Fatigue towards the end of the school day
  • A “pulling” feeling in one eye
  • Hitting a baseball late or early most of the time
  • Struggling to catch a pop fly or is afraid of the ball
  • Shooting a basketball short or long most the time
  • Performing poorly at racquet sports
  • Difficulty with moguls when skiing or reading the green in golf
  • Avoiding stacking blocks or building things
