Young children are increasingly familiar with computers and videogames, oftentimes being more sophisticated in their use than their parents. Vision screening software is easy to distribute via CDs or the internet. Computers are readily available in virtually all schools and the cost of computer technology continues to decline even as performance improves. Computer software applications allow standardization of logic protocols for vision screenings and the videogame format allow for automated testing. Automated testing eliminates the need for large scale training and certification of vision screening proctors and instead can allow vision screenings to be performed by untrained lay volunteers or personnel already available in schools. Finally, since responses of children being tested are inputted directly into the computer, results may be printed instantaneously at the end of testing. Computer data may be warehoused locally or offsite via the internet to help coordinate medical follow-up for those children identified at risk, monitor the success of the program, and facilitate epidemiological analysis of vision disorders. Prototype VisionQuest 20/20 software currently performs standardized visual acuity assessments of each eye and stereopsis testing while a child "plays" a 2-3 minute video game.
