At what age is it usual to begin vision screening for children?

Vision screening for children typically begins at around 3 years of age, which aligns with developmental milestones when children can better cooperate and respond to vision tests. At this age, children are starting preschool and are more likely to be in environments where vision demands increase. This early screening helps to identify potential vision issues that could affect learning and development before they become significant problems.

While some assessments may occur earlier, such as during routine pediatric checkups, formal vision screening is most commonly recommended to start at age 3. This allows for timely intervention if any visual impairments are detected. Screening at later ages, such as 5 or 7 years, may catch some issues but could miss critical early intervention opportunities that are essential for proper development.

Therefore, starting vision screenings at age 3 ensures that children have the best chance to develop healthy visual skills as they grow.
