Universal vision testing for preschoolers urged in South Australia

Health professionals and educators are calling for universal vision screening for preschool-aged children in South Australia, citing growing concerns about undetected visual impairments that can impact learning, development, and long-term wellbeing.

The push follows new data from optometrists and researchers indicating a sharp rise in the number of young children entering school with previously undiagnosed vision issues. Experts argue that early detection could prevent significant developmental delays and behavioural challenges in the classroom.

Currently, South Australia does not offer universal vision testing in preschools. Instead, screening is typically conducted during school entry health checks in Reception (the first year of primary school). However, many specialists say this is too late to catch some of the most critical issues, particularly those affecting visual development during the formative early years.

A case for early intervention

Optometrist David Wilson, who has worked extensively with young children across metropolitan and regional SA, told ABC News that conditions like amblyopia (lazy eye), strabismus (crossed eyes), and refractive errors often go unnoticed until they significantly affect a child’s performance in school.

“These are not problems a three- or four-year-old can explain to you,” Wilson said. “They don’t know that what they’re seeing isn’t normal.”

According to the report, about one in five children can enter school with some form of untreated vision problem. This can manifest as poor concentration, difficulty with reading or writing, and even be misinterpreted as behavioural concerns or developmental delay.

Calls for a statewide approach

Early childhood advocates, including preschool directors and sector researchers, are urging the SA Government to implement a statewide program offering free vision checks in preschools, much like hearing screenings or dental checks.

Such programs already exist in other jurisdictions. In New South Wales, for example, the StEPS (Statewide Eyesight Preschooler Screening) program provides free vision testing for 4-year-olds through preschools and early learning centres. Advocates say this model could be replicated in South Australia with high impact and relatively low cost.

Implications for early learning outcomes

Vision is a foundational skill for learning, and its role in early childhood development cannot be understated. Children with undetected vision issues may struggle to participate fully in play-based and pre-literacy activities, key areas of focus in early childhood education and care settings.

Early childhood services are encouraged to be aware of the signs of possible vision problems and to work closely with families on referrals to appropriate health professionals when concerns arise.

While the SA Government has yet to commit to a universal vision screening program, health authorities say discussions are ongoing. In the meantime, professionals recommend that parents arrange a comprehensive eye check for children by age 4, even if no symptoms are apparent.
