Vision problems can affect learning and development in children. Developmental optometry evaluates vision issues beyond visual acuity to identify problems like eye teaming, tracking, and visual processing. Vision therapy uses in-office procedures and home activities to treat issues through neurological training, helping children overcome challenges mistaken for conditions like ADHD. Seeing a developmental optometrist allows specialized assessment and treatment including glasses with bifocals or prisms and vision therapy.
