The ideal vision screening method should be accurate (sensitive and specific for clinically significant visual problems amenable to treatment), standardized, easy to administer and interpret with little training, cost effective, universally available to children, and capable of collecting data to ensure medical follow-up is received by those who need it as well as to collect epidemiological information and monitor the success of the program year after year. The Amblyopia Foundation of America (AFA) has conceptualized how automated computer software which assesses vision while a child "plays" a video game could potentially meet the requirements for an ideal vision screening system for children old enough to cooperate.
