It’s important to get your eyes tested at least every two years, even for younger children. If the optometrist can spot a problem and treat it early on, their performance in school will remain unhindered. Regular eye exams can help identify other serious health problems such as diabetes, high blood pressure, high cholesterol and even cancer.
