The American Optometric Association recommends that adults aged 19 to 40 receive an eye exam at least every two years. If you are at risk for eye problems due to a family history of eye disease, diabetes, high blood pressure or past vision problems, your doctor of optometry may recommend more frequent exams. In between examinations, if you notice a change in your vision, contact your doctor. Detecting and treating problems early can help maintain good vision for the rest of your life.
