Eye test - refraction; Vision test - refraction; Refraction

There are no risks.

You should have a complete eye examination every 3 - 5 years if you have no problems. If your vision becomes blurry, worsens, or if there are other noticeable changes, schedule an eye examination immediately.

After age 40 (or for people with a family history of glaucoma), eye examinations should be scheduled at least once a year to test for glaucoma. Anyone with diabetes should also have an eye exam at least once a year.

People with a refractive error should have an eye examination every 1 -2 years, or whenever their vision changes.
