Prism Adaptation Therapy

What is Vision Rehabilitation?

Prism Adaptation Therapy is a rehabilitation technique used to improve spatial neglect, a condition commonly seen after stroke where individuals ignore one side of their surroundings. The therapy uses special prism glasses that shift the visual field to one side. When patients perform repeated tasks like pointing or reaching while wearing these prisms, their brain gradually adapts to the shift.

What is Spatial Neglect?

Spatial neglect is a neurological condition where a person has reduced awareness of one side of their environment (usually the left side), despite having normal vision. It commonly occurs after a stroke or brain injury and can affect daily activities like walking, eating, or reading.

How Does It Work?

Prism glasses shift the visual field to one side. When performing repeated tasks (like pointing or reaching), the brain gradually adapts to this shift. After removing the prisms, this adaptation helps improve attention and movement toward the previously neglected side.

When Should You Consider This Therapy?

If a person shows signs of ignoring one side, bumping into objects, or difficulty using one side of the body after a stroke or brain injury, prism adaptation therapy may be beneficial
