Back to School: Why a Vision Exam Belongs on Every Child's Checklist

School Vision Screenings Are Not Eye Exams

Most school districts conduct vision screenings — a nurse or volunteer holds up an eye chart and asks children to read letters at distance. These screenings detect roughly 30-40% of vision problems. They miss nearly everything that doesn't affect distance acuity: farsightedness, eye teaming problems, tracking disorders, and early amblyopia all pass a standard screening with flying colors.

A comprehensive eye exam at an optometry practice is a completely different thing. It takes 30-45 minutes, uses specialized equipment, and evaluates how both eyes work together — not just whether your child can read a chart at 20 feet.

Signs Your Child May Have a Vision Problem

• Sitting very close to the TV or holding books close to the face
• Squinting, closing one eye, or tilting the head
• Frequent headaches, especially after reading
• Losing their place while reading or skipping lines
• Short attention span for visual tasks
• Avoiding reading or complaining that letters move
• Rubbing eyes frequently

How Often Should Children Have Eye Exams?

The American Optometric Association recommends:

• 6–12 months: First comprehensive exam (often covered by insurance)
• Age 3: Second exam before preschool
• Age 5–6: Before first grade
• Ages 6–18: Annually, especially with any academic concerns or if the prescription is changing

Children with myopia — nearsightedness — particularly benefit from more frequent monitoring, as prescriptions can change rapidly during growth years and myopia progression increases the risk of serious eye disease in adulthood.

What We Look For in a Pediatric Exam

Beyond the prescription, we assess visual acuity at distance and near, eye alignment and teaming, tracking and focusing ability, depth perception, color vision, and the health of all internal eye structures. For younger children who can't read letters, we use picture charts and objective measurement techniques that don't require any verbal response.

We see children of all ages at Harnos Optometry. Back-to-school season fills up quickly — if your child hasn't had an exam this year, now is the time to schedule.
