Most adults should have a full eye exam every 1–2 years, but the ideal schedule depends on age, symptoms, and risk factors like diabetes, high blood pressure, or a family history of eye disease. Children, older adults, and people with existing eye or health conditions usually need more frequent checks, sometimes yearly or as advised by their eye doctor.

General guidelines

  • Healthy adults with no symptoms or known eye disease are commonly advised to have an eye exam about every 1–2 years.
  • Some insurers and health organizations use slightly wider ranges (for example, every 2–4 years in your 40s if low risk, and every 1–2 years after 65).
  • If you notice changes in vision (blur, floaters, flashes, eye pain, headaches, double vision), you should book an exam as soon as possible, regardless of when your last check was.

By age group

  • Children: Many specialists recommend at least one comprehensive eye exam before school age (around 4–5 years), with further exams or school screenings as advised if issues appear.
  • Adults 20–39: If you have no symptoms and are low risk, exams roughly every 2–5 years are often considered acceptable; some clinicians still prefer 1–2 years, especially with heavy screen use.
  • Adults 40–64: Because risks like glaucoma and presbyopia rise, many guidelines recommend a baseline exam at 40, then every 2–4 years if low risk.
  • 65 and older: Most recommendations tighten to every 1–2 years even if you feel your vision is fine, to catch cataracts, macular degeneration, and glaucoma early.

When you may need more often

You may need yearly or even more frequent exams if any of these apply:

  • Diabetes, high blood pressure, or other systemic diseases affecting blood vessels.
  • Family history of glaucoma, macular degeneration, or serious eye disease.
  • Previous eye surgery, trauma, or known conditions like glaucoma or diabetic retinopathy.
  • Wearing contact lenses, especially if you’ve had irritation, infections, or prescription changes.
  • Being in higher‑risk groups for glaucoma (for example, African American or Hispanic adults often receive advice to test more frequently from a younger age).

Why regular eye tests matter

  • Eye exams can reveal silent conditions such as glaucoma, diabetic retinopathy, and early macular degeneration before you notice symptoms.
  • They sometimes detect general health problems like diabetes and high blood pressure because eye blood vessels and the optic nerve show early damage.
  • In the last few years, rising screen time has made dry eye, eye strain, and focusing problems more common, which clinicians now cite as another reason not to skip routine checks.

Quick takeaways for you

  • If you are a healthy adult with no symptoms: aiming for an eye exam every 1–2 years is a safe, easy-to-remember rule.
  • If you have any risk factors or notice changes: treat yearly (or as your eye specialist recommends) as a minimum.
  • If you are unsure: ask your optometrist or ophthalmologist; they can tailor a schedule based on your age, medical history, and how your eyes look at your next exam.
