If your kid is persistently complaining of poor vision, then it's time to visit a therapist. Neither autistic nor hyperactive. Perhaps your kid is just seeing double at times, Forbes TV reported. Experts estimate that 5 percent of school-age children have convergence insufficiency.
They can suffer headaches, dizziness and nausea, which can lead to irritability, low self-esteem and inability to concentrate. Doctors and teachers often attribute the behaviour to attention disorders. Doctors recommend a dilated eye exam and a check of eye teaming and focusing skills.
Testing includes using a pen or finger to test for the "near point of convergence," as well as a phoropter, which uses lenses and prisms to test the eyes' ability to work together.
