Eye Exam Q&A

How does an eye exam determine if you need glasses?

When you see Dr. K for a comprehensive eye exam, he’ll test your vision and provide a thorough examination. If it’s your first eye exam at Dr. K’s 20/20 Vision Center, Dr. K will also review your medical and family history.

To test your visual acuity, Dr. K will ask you to read letters from a standardized eye chart. If you need corrective lenses, Dr. K will have you look into an instrument called a phoropter to determine the right prescription for your glasses or contacts.

What tests are performed during an eye exam?

During your exam, Dr. K will examine how well your pupils function and test your peripheral (or side) vision. That’s essential because deteriorating peripheral vision might indicate a serious issue, such as glaucoma.

He’ll check your cornea, iris, and lens, and, if appropriate, may use drops that dilate your eye to get a better view of your retina and optic nerve.

Dr. K will also perform an ocular motility test, which evaluates how your eyes move and align, and how the muscles function, and a tonometry test to measure your eye pressure.

Who needs an eye exam?

Everyone should have a baseline eye exam early in life. That way, if you — like most people — begin noticing focusing problems at around age 40, your doctor can determine whether your eye health has changed.

Children up to about age 18 should have their eyes checked every one to two years. And people with conditions that can affect their eyes — such as diabetes — should be checked every year.

You should also have your eyes checked as soon as you notice any changes in your vision.

An exam will allow Dr. K to screen for any indicators of eye diseases, especially if you have specific chronic conditions, like high blood pressure or a family history of eye disease.

If you wear contacts lenses or glasses, you should see your optometrist annually.
