What does a comprehensive eye exam consist of?

A thorough eye examination consists of a variety of standard tests designed to measure visual acuity and other vision faculties, as well as observe the health of the eye and check for common eye diseases.  There is no pain or discomfort associated with an eye exam, and eye examinations typically take less than an hour.

General eye exams can diagnose a variety of eye conditions early on and are the best way to preserve good vision.  For children, strabismus (crossed eye) and amblyopia (lazy eye) can often be diagnosed and treated in early childhood, avoiding life-long vision impairment.  Also, rare eye conditions from birth (like congenital cataracts) can be diagnosed and treated during eye exams.  For all ages, refraction tests during eye exams can determine whether prescription eyewear would be beneficial, and what power is necessary.  Furthermore, many debilitating eye diseases can be diagnosed before noticeable symptoms occur, potentially making the difference between minor damage and major vision loss.

Eye exams are recommended annually throughout all phases of one’s life.  As early as the first three years, infants should have their vision checked with an eye examination as part of regular pediatric checkups. Eye examinations are also more frequent for patients monitoring a diagnosed eye condition, or with a hereditary predisposition to an eye disease.

Common tests and evaluations during an eye exam include:

  • Introductory interview:  The doctor will ask basic questions about a patient’s medical history and eye health history during this initial process of the eye exam.
  • External examination:  In this step of an eye exam, the doctor inspects all outward visible parts of the eye and surrounding tissue.
  • Pupil inspection:  The patient’s pupils will be inspected for equal size and regular shape during this portion of the eye exam.  Then the doctor tests how they react to light and objects at various distances.
  • Eye muscle health and mobility:  During this process of the eye exam, the eye movement is checked in six directions (corresponding to the six extraocular muscles), as well as tracking a moving object (such as a pen).
  • Visual field:  The patient covers one eye at a time, and with the other eye gazing straight ahead, identifies objects in peripheral vision (often simply the number of fingers the doctor is showing.)
  • Visual acuity: During this process of eye examinations, a visual acuity test is performed, which is a common means of measuring visual acuity is the Snellen chart.  This is a large card or projection with progressively smaller horizontal lines of random block letters.  The test determines how well a patient can discern detail at a given distance.  Patients taking this test will cover one eye and then read aloud the letters of each row, starting from the top.  The smallest row that can be accurately read indicates the patient’s visual acuity in that eye.
  • Refraction:  This test during the eye examinations are used to find the best-corrected vision, if necessary for prescription eyewear or contacts.  During the eye exams, the doctor will try various lenses in front of each eye, as the patient focuses on a chart at a distance or up-close, to help determine the best power of correction.
  • Color vision:  The color vision test during the eye examination is when the doctor shows the patient a series of images with symbols embedded in color dots or patterns.  Based on the patient’s ability to identify the symbols during the eye exams, certain types of colorblindness can be diagnosed or ruled out.
  • Ophthalmoscopy:  The ophthalmoscopy test during eye exams is often done with an ophthalmoscope, a handheld instrument with a light and magnifying lenses.  Alternatively, the doctor may use other means, such as a slit lamp, which affords a more three-dimensional view.  Ophthalmoscopy aims to inspect the retina and surrounding internal eye.  During the eye exam, this test can help diagnose problems with the retina or detachment of the retina, and monitor diseases like glaucoma and diabetes.  Opacity in the eye can indicate a cataract.  Sometimes during the eye exam, the doctor will dilate the pupils with eye drops, to gain a wider view of the internal eye.
  • Tonometry:  The Tonometry test during the eye examination measures intraocular pressure, which can be a sign of glaucoma if pressure is abnormally high.  Internal eye pressure is measured either with a puff of air at the cornea or brief direct contact with the cornea, to measure how easy it is pushed inward.
