One important thing to understand about VT is that it is not the same thing as "eye exercises" -- this is a very outdated and over-simplified explanation for what VT is and what it does. According to the College of Optometrists in Vision Development, the goal of VT is not to strengthen eye muscles. Your eye muscles are already incredibly strong, and the vision problems VT aims to treat are rarely caused by muscle weakness. Instead, vision therapy aims to retrain the learned aspects of vision through the recently-understood concept of neuroplasticity.
