Amblyopia is the most common cause of visual impairment among young children, and its onset is both detectable and preventable if detected sufficiently early. Unfortunately the brain’s development of vision is completed by age 2-3; therefore such vision abnormalities are not correctable after approximately age 3.

Although vision screening is mandated in every state, it usually is not performed until age 4-5 when the child enters school and is conducted usually by an uninvolved school nurse using a letter chart that has been shown to have poor sensitivity and specificity at detecting such vision deficits because the child is not involved in the testing.

Sinclair Technologies has developed an interactive children’s video game, Kidsight, that measures the central vision and field of vision while the child plays the game. Play time requires approximately 4-5 minutes, during which the child’s central and peripheral vision is measured in each eye under a range of contrast, illumination, and color conditions. Work is ongoing to test stereopsis (depth perception). The game has been tested in kiosk-style environments to date with great success. Sinclair Technologies is currently re-developing the game for testing 1-3 year old children with hand held tablets utilizing a more user age-directed experience.
