Comprehensive Eye Exam Q & A

What is a comprehensive eye exam?

A comprehensive eye exam is like a physical exam for your eyes. The team at InFocus Vision assesses eye health and vision during the exam, helping to identify potential eye problems. Taking good care of your eyes early may help you maintain your normal vision or prevent further vision loss.

How often should I get a comprehensive eye exam?

Dr. Doa determines how often you need a comprehensive eye exam, taking into consideration your current eye health, vision, and age. In general, you should have your eyes thoroughly examined every one to two years.

What can I expect during a comprehensive eye exam?

The comprehensive eye exam is a thorough evaluation of both you and your eyes that checks eye health and vision. Your optometrist begins the examination by first reviewing your medical history, because certain health conditions, such as diabetes, require special eye care.

Visual acuity

During your visual acuity test, your optometrist measures how clearly you see out of each eye by having you read letters off a chart at various distances. Your visual acuity is written as a fraction, where 20/20 is considered perfect vision. If your vision is 20/60 that means you need to get within 20 feet to clearly see a letter that should be easily read at 60 feet.


Keratometry measures the curvature of your cornea. Your optometrist may need this measurement if you plan on getting contact lenses.


The refraction test determines your lens prescription and whether you’re nearsighted, farsighted, or have astigmatism, which is a curvature of the eye that affects vision.

Eye movement

Good eye health and vision requires coordinated eye movement. During this portion of the exam, your optometrist at InFocus Vision uses various tools to see how your eyes move and work together.

InFocus Vision also offers a digital eye exam, which maps the curvature of your cornea and can be used to monitor the smallest structural changes that occur over time.

Will I need special testing?

You may need special testing beyond the basic tests of the comprehensive eye exam if the optometrist at InFocus Vision wants to confirm or rule out a health condition. This may include measuring eye pressure to assess for glaucoma or a more thorough examination of the inside of your eye to assess for cataracts or macular degeneration with Optomap® Imaging.
