How often should a child’s vision be screened after age three?

The recommendation for vision screening in children is based on the understanding that vision can change significantly during different developmental stages. After the age of three, children typically go through significant growth and development phases that can affect their eyesight. Screening at each developmental stage allows for the early detection of any vision problems, which is crucial for effective intervention and treatment if necessary.

Regular screenings can identify issues such as refractive errors, strabismus, or amblyopia, which can lead to permanent vision impairment if not addressed promptly. By evaluating vision regularly throughout childhood, healthcare providers can ensure that potential issues are caught early, allowing for timely corrective measures such as glasses, therapy, or surgery.

Other options do not align with current guidelines. Screening only once in a lifetime does not account for the possibility of developing vision problems as the child grows. Annual screenings may not be necessary for every child, as some may not have any detected issues requiring such frequent assessments. Five-year intervals are typically too long for reassessment, as significant changes can occur more frequently than that. Therefore, the best approach is to screen at various developmental stages to ensure optimal vision health throughout childhood.
