The Canadian Association of Optometrists recommends that children have their first eye exam at 3-6 months of age to detect any potential vision problems early on. This is because vision plays a critical role in a child's development and learning, and any vision problems that go undetected can lead to long-term issues. It's important to note that the recommendation for the first eye exam may vary depending on the child's individual circumstances and risk factors, so it's always best to consult with an optometrist or healthcare provider for personalized advice. After the first exam, regular eye exams are recommended every one to two years to ensure that any changes in vision are detected and addressed promptly.
