Refraction test - Risks

Alternative Names

Eye test - refraction; Vision test - refraction

What the risks are:

There are no risks.

Special considerations:

A complete eye examination should be done every 3 - 5 years if there are no problems. If vision becomes blurry, worsens, or if there are other noticeable changes, an eye examination should be scheduled immediately.

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

People with refraction problems should have an eye examination every 2 - 3 years.
