Unlike other forms of exercise, the goal of optometric vision therapy is not to strengthen eye muscles. Your eye muscles are already incredibly strong. Instead, vision therapy aims to retrain the learned aspects of vision through the concept of neuroplasticity.
Optometric vision therapy should not be confused with any self-directed program of eye exercises which is or has been marketed to the public. In-office vision therapy under the supervision of an optometrist is supported by ongoing evidence-based scientific research.
