How often should I get an Eye Exam? Most people should have an eye exam every 1-2 years or so. Since many eye diseases have no immediate symptoms until significant damage is done, regular eye exams are one of the most important things you can do - both for your vision and your overall health. Potential vision disorders that an eye exam may detect include cataracts, glaucoma, and retinal disease. But eye exams can also help to detect other health disorders such as diabetes, high blood pressure, and multiple sclerosis.
