What age should vision screening begin in children?

Vision screening for children typically begins at the age of three years, which is why this answer is the most accurate. At this age, children are generally developmentally ready to follow simple instructions and participate in screening tests that help assess their visual acuity. Early screening is crucial because many vision problems can be detected and treated more effectively when identified early.

While some assessments of vision can occur at birth, such as evaluating for reflex responses to light and tracking movements, comprehensive vision screening protocols are not fully applicable until children are older. By the age of one, a pediatrician may perform a basic examination of the eyes but more formal screening associated with acuity tests is more suitable for preschool-aged children. By five years of age, most children are already in school systems that include routine screenings, but initiating regular assessments by the age of three provides a critical window for addressing potential issues before they can impact learning and development.
