Are children wearing glasses included in the vision screening program?

In many vision screening programs, including those implemented by the Illinois Department of Public Health, the focus is primarily on identifying undiagnosed vision problems. Children who are already wearing glasses typically have had their vision assessed and corrective measures put in place. Therefore, they may not fall under the criteria for routine screening, as the objective of these programs is to detect new cases of vision impairment among children who have not yet received treatment.

This approach minimizes redundancy in testing for children whose visual impairments have already been addressed through corrective lenses, ensuring that resources are allocated effectively towards identifying those in need of further assessment or intervention.
