Vision Therapy Techniques and Tools

Did you know?

  • Between 70% and 80% of how we learn and interact with our environment is (at least in part) mediated by vision.
  • More than 50% of persons served with an acquired brain injury (traumatic brain injury, stroke, etc.)


The most common visual deficits associated with brain injury include visual field loss (the loss of a portion the field of vision in one or both eyes), visual inattention (an unawareness or perceptual loss of vision to one or both sides...usually to the left from a right parietal injury), and double vision (caused by misalignment of the eyes and/or difficulty coordinating eye movements when focusing on or tracking objects). Other visual deficits include photo-phobia(sensitivity to light), and difficulty producing tears/lubrication for the eye (usually due to a decreased blink rate or inability to completely close the eye).


On With Life's therapists have a number of tools with which they address the rehabilitation of vision. The process begins with an evaluation by Dr. Beth Triebel, OD, who specializes in vision therapy. Dr. Triebel, our Occupational Therapy Department, and our persons served, work together to develop a vision therapy plan, which might include:

  • Techniques to increase awareness of the vision deficit and help the person served learn strategies to compensate for the vision loss.
  • The use of the DynaVision to provide structured feedback to the person served about the amount of time it takes for them to see information in different parts of their visual space. This feedback is particularly helpful in the rehabilitation of visual inattention by facilitating awareness. For persons served with visual field loss, the DynaVision helps create visual scanning patterns and strategies to best compensate for the vision they have lost.
  • The use of spot patching and special red/green glasses to facilitate the person served's ability to coordinate the movement of the eyes.

Vision therapy is a key component in the rehabilitation process and plays an integral role in allowing the person served to participate as fully as possible in their life's activities.
