 Behavioral optometry has been proposed as being of benefit for children with Attention deficit hyperactivity disorder and autism – this proposal is based on the idea that since people with these conditions often have abnormal eye movement, correcting this may address the underlying condition.Evidence supporting this approach is however weak; the American Academy of Pediatrics, the American Academy of Ophthalmology and the American Association for Pediatric Ophthalmology and Strabismus have said that learning disabilities are neither caused nor treatable by visual methods.Behavioral optometry is considered by some optometrists to have its origins in orthoptic vision therapy.
