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.

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.
