Can I get an eye exam every 2 years?

Editorial team Published on

Yes, many healthy adults can get an eye exam every 1 to 2 years, but the right schedule depends on your age, health, and whether you wear corrective lenses.

General Guidelines by Group

  • Healthy Adults (Ages 18–39): Every 1 to 2 years is often fine if you have no symptoms or risk factors, though some professional groups suggest more frequent checks.
  • Adults (Ages 40–64): Annually or every 2 years; yearly exams are frequently advised as risks for conditions like presbyopia, cataracts, and glaucoma increase.
  • Seniors (Ages 65 and older): Annually is recommended to screen for age-related eye diseases.
  • Contact Lens Wearers: Annually, because contacts sit directly on the eye and require yearly checks for fit and eye health.

When You Might Need Exams Sooner

  • Medical Conditions: If you have diabetes, high blood pressure, or other systemic health issues.
  • Family History: If close relatives have glaucoma, macular degeneration, or other serious eye diseases.
  • Vision Changes: If you experience blurriness, eye strain, frequent headaches, or trouble seeing at night.

Is it okay to get an eye exam every 2 years?

Yes, an eye exam every two years is often acceptable for healthy, low-risk adults under 40 who do not wear contact lenses, though many eye care organizations now recommend annual checks.

When Every 2 Years Works

  • Low-risk adults: Ages 18 to 39 with clear 20/20 vision and no symptoms.
  • No medical issues: Absence of systemic health conditions or family history of eye disease.
  • No corrective lenses: You do not wear glasses or contact lenses full-time.

When You Need Annual Exams

  • Contact lens wearers: Need a yearly check to assess corneal health and fit.
  • Age 40 and older: Risk for glaucoma, cataracts, and presbyopia increases, often requiring a baseline screening at 40 and more frequent visits.
  • Health conditions: Diabetes, high blood pressure, or a family history of eye disease.
  • Vision changes: Squinting, blurry vision, or frequent headaches.

Do I really need an eye test every 2 years?

Most healthy adults need an eye test every one to two years, though some people need them more often depending on their age, health, and risk factors.

Why the 2-Year Rule Exists

  • Vision changes: Your prescription can shift gradually without you noticing it right away.
  • Silent conditions: Comprehensive eye exams catch serious issues like CDC Why Eye Exams Are Important glaucoma, cataracts, or macular degeneration before they cause noticeable vision loss.
  • General health: An eye exam can reveal early signs of systemic health problems like diabetes and high blood pressure.

Who Needs More Frequent Tests

  • Older adults: People aged 60 and older face a higher risk of age-related eye diseases and often need annual or biennial checks.
  • People with health conditions: Individuals with diabetes need an exam every year to monitor for diabetic retinopathy.
  • Contact lens wearers: Wearing contacts increases the risk of eye infections and irritation, so yearly checks are standard.
  • Family history: If you have a family history of glaucoma or macular disease, your doctor may suggest yearly visits.
