[Treatment of Convergence Insufficiency
Treatments for CI can be categorized as active or passive:

Active treatment: A multi-site randomized clinical trial funded by the National Eye Insitute has proven that the best treatment for convergence insufficiency is supervised vision therapy in a clinical office with home reinforcement (15 minutes of prescribed vision exercises done in the home five days per week). The scientific study showed that children responded quickly to this treatment protocol...75% achieved either full correction of their vision or saw marked improvements within 12 weeks.8

Passive treatment: Prismatic (prism) eyeglasses can be prescribed to decrease some of the symptoms. Although prism eyeglasses can relieve symptoms, they are not a "cure" and the patient typically remains dependent on the prism lenses. In addition, adaptation problems can lead to the need for stronger prescriptions in the future. Scientific research as well as optometric and ophthalmological textbooks agree that the primary treatment of convergence insufficiency should be vision therapy.1]
