Eye Health Screenings: Getting Kids Ready for the Classroom

Why Vision Matters for Learning.

Vision is fundamental to almost everything children do in the classroom, from reading the blackboard to participating in group activities and social interactions. Undetected vision problems can be easily mistaken for learning difficulties, attention issues, or behavioral challenges. Children often assume everyone sees the way they do and rarely complain about their eyesight, which means problems can persist without identification during key developmental periods. As Dr. Shaina Nensi, President of the Ontario Association of Optometrists, explains, parents are often surprised to learn that vision problems can be mistaken for behavioral or learning difficulties.

Recommended Eye Exam Schedule.

The Canadian Association of Optometrists recommends the following schedule for comprehensive eye exams:

For children without family history of eye problems and no immediate vision concerns, an eye exam before school entry at around 3.5 years of age is recommended, followed by exams annually once in school.

Common Vision Problems in Children.

The most frequent issues are often the easiest to correct with a simple pair of glasses: nearsightedness (trouble seeing distance), farsightedness (difficulty seeing close up), and astigmatism (blurred or distorted vision at all distances). Myopia rates in Canadian children have increased significantly in recent years, with one in three children with myopia previously undiagnosed. Other conditions include amblyopia (lazy eye) and strabismus (eye misalignment), both of which can be treated effectively when caught early but become more difficult to correct if left undiagnosed past age eight.

Warning Signs for Parents.

While physical signs can include an eye that wanders, parents should also watch for behavioral clues such as squinting, sitting too close to the TV, rubbing eyes frequently, complaining of headaches or tired eyes, and avoiding reading or close work. Irritability, short attention span, or visible frustration with tasks can also indicate an underlying vision issue.

Programs and Coverage Across Canada.

Eye exams for children are covered by provincial health plans across Canada. In Ontario, annual eye exams are covered by OHIP for anyone 19 years and younger. Several provinces offer the Eye See…Eye Learn™ program, providing kindergarten students with a free pair of eyeglasses if needed. This initiative is available in Alberta, Manitoba, and Ontario, helping remove financial barriers to proper vision care for young learners.

Protecting Your Child’s Eyes.

Beyond the eye exam, parents can promote healthy vision by encouraging at least two hours of outdoor play daily, as studies show this can help slow the progression of nearsightedness. Following the 20-20-20 rule—every 20 minutes, taking a 20-second break to look at something 20 feet away—can help reduce digital eye strain from screen use. Sunglasses and hats outdoors, along with proper eye protection during sports, round out a comprehensive approach to eye health.

Seeing Students Start Strong.

A comprehensive eye exam is one of the most important items on a child’s back-to-school checklist. With nearly one in four school-aged children having a vision problem, early detection and treatment are key to catching issues before they impact learning, making the eye exam a non-negotiable part of school readiness.
