Brief Summary:
The purpose of this research study is to see how well the treatment of a participant's eye coordination and/or focusing problems improves eye muscle responses and symptoms of eyestrain. We will use an entertainment device called a virtual reality headset to play a custom-designed video game to find out how well the treatment of binocular vision improves a participant's coordination and/or focusing problem. The virtual reality headset uses eye-trackers to monitor progress in a totally objective manner. Objective testing allows the doctor to determine the results without relying on a participant's ability to answer questions or respond verbally in any way. We will compare the results of a participant before and after playing the video game.

    Normal range is < 6 cm

Secondary Outcome Measures :
  1. Convergence Insufficiency Symptom Survey (CISS) [ Time Frame: up to 4 weeks post-therapy ]
    Normal range is < 21 for adults and < 16 for pediatrics

  2. Vision Quality of Life with Time Survey (VisQuaL-T) [ Time Frame: up to 4 weeks post-therapy ]
