During which stage is it recommended for children to undergo regular vision screening?

Regular vision screening for children is crucial for early detection of any problems that could affect their visual development and overall functioning. The recommendation for regular vision screening begins after age 3, as this is a critical period for a child's visual development. At this age, children can participate in basic vision screening tests, which help identify issues such as amblyopia (lazy eye), strabismus (crossed eyes), and refractive errors.

Screening at this stage, and then periodically during childhood, ensures that any vision problems can be addressed before they impact a child's learning and development. Furthermore, establishing a routine for vision checks helps in monitoring the child's eye health as they grow, providing opportunities for timely interventions if necessary.

In contrast, limiting vision screening to specific stages, such as only during preschool or just before starting school, does not consider that vision can continue to change and develop as a child matures. The age of 13 is too late to start regular screenings because many vision issues become more difficult to address as a child gets older without early intervention. Therefore, starting vision screening after age 3 and continuing it regularly aligns with best practices in pediatric healthcare.
