Home Vision test Amblyopia Q&A Find an eye doctor

This site was created as a public service and was made possible through funding from the Primary Children’s Medical Center Foundation in Salt Lake City, Utah, as well as the National Library of Medicine.

It was created in the Department of Medical Informatics at the University of Utah by David P. Taylor under the supervision of Richard J. Olson, M.D., Associate Professor of Clinical Ophthalmology, Department of Ophthalmology and Visual Sciences, University of Iowa. Dr. Olson's specialty is Pediatric Ophthalmology and Strabismus.

The Flash vision test and other drawings on the site were implemented by Joey Gates.

The vision screening test on this site was adapted from "The Amblyopia Treatment Study Visual Acuity Testing Protocol" by Holmes JM, Beck RW, Repka MX, et. al. However, the vision screening test has not yet been validated against a standard ophthalmological visual acuity exam.

We are anxious to improve the quality of this site. Please address comments and questions to:
