Welcome to the Vision In Preschoolers (VIP) Study web site

The primary goal of the VIP Study is to identify whether vision-screening tests can accurately identify preschool-aged children who would benefit from a comprehensive vision examination because of signs of amblyopia, strabismus, and/or significant refractive error. We hope that this site answers your questions about the VIP Study and preschooler vision screening.

Did You Know?

…that 1 of every 4 children may have a vision problem that no one knows about?

It’s important to find vision problems when children are young but few children have eye exams before they start school. Vision problems can cause headaches, eyestrain, and trouble concentrating on school work. Finding vision disorders
early is the best way to prevent permanent vision loss and treatment for vision problems can lead to a better school experience and a brighter future. Vision disorders are the fourth most prevalent class of disability in the United States and the most prevalent handicapping conditions in childhood.
