What Happens During an Eye Exam: See the Process Clearly

Your eyes are as important as any organ of your body, and it’s essential to take care of them. Getting an eye exam is the first step to take if you want to ensure that your eyes are functioning correctly. Eye exams are not just for people who have vision problems, but everyone needs to get their eyes checked regularly.

To help you understand what happens during an eye exam, this article will guide you through the process.

Why Get an Eye Exam?

There are several reasons why you need an eye exam:

  • To check your vision: Your vision can change over time, and an eye exam can help in identifying these changes.
  • To detect eye diseases: An eye exam can detect early signs of eye diseases like cataracts, glaucoma, and macular degeneration.
  • To detect systemic diseases: An eye exam can detect signs of systemic diseases like diabetes, high blood pressure, and high cholesterol.
  • To determine eyeglass or contact prescription: An eye exam helps determine the right prescription for eyeglasses or contact lenses.

The Eye Exam Process

The following are the procedures that you may undergo when you get a comprehensive eye exam:

Case History and Symptoms

The first step in the process is to sit down with the optometrist or ophthalmologist to discuss your medical and visual history. The optometrist will want to know about existing medical conditions, past surgeries, medications you are currently taking, and any symptoms that you are experiencing.

Visual Acuity Test

The visual acuity test is used to measure how well you can see letters on a chart. If you wear glasses or contact lenses, you will be asked to take the test with and without them. The test helps determine whether you have nearsightedness, farsightedness, or astigmatism.

Refraction Test

The refraction test determines your eyeglass or contact lens prescription. During the test, the optometrist uses a phoropter, which is a device that contains various lenses. You will be asked to look through the device and answer which lens provides clearer vision.

Eye Muscle Test

The eye muscle test is used to check how well your eyes work together. The optometrist will ask you to follow a moving object, which helps determine eye alignment, and how well they move.

Visual Field Test

The visual field test checks for blind spots in your visual field. During the test, you will be asked to look at a target in front of you, and small lights will be flashed in your peripheral vision. You will need to press a button when you see the lights.

Eye Pressure Test

The eye pressure test, also known as tonometry, checks for signs of glaucoma. During the test, a device called a tonometer will be used to measure the pressure within your eyes.


If necessary, the optometrist may dilate your pupils. Dilation involves putting drops into your eyes that cause your pupils to widen. This helps the optometrist to see the back of your eyes more clearly, which aids in the detection of eye diseases.

Preparing for Your Eye Exam

Before your eye exam, it’s essential to be prepared in the following ways:

  • Bring your glasses or contact lenses if you wear them.
  • Bring a list of medications you are currently taking.
  • If you have any medical conditions, have the relevant information with you.
  • If you require special accommodations like large print or wheelchair access, inform the clinic before your appointment.
  • Wear comfortable clothes.


An eye exam is a simple and painless process that can help ensure that your eyes are healthy and functioning correctly. Scheduled eye exams are essential for people of all ages and recommended at least once every two years for people under 50 and once a year for people over 50.
