An eye exam is a comprehensive review of your eye health and vision strength. First, we’ll ask you about your medical history and any vision problems you might be experiencing. Then we proceed with a series of tests. Your age and/or medical history will determine which tests we conduct. We’ll then discuss what we found during the exam and answers questions you have about your eyes. Part of the examination, such as taking your medical history and the initial eye test, may be performed by one of our clinical assistant.
Several different tests may be performed during the eye exam. The tests are designed to check your vision and to examine the appearance and function of all parts of your eyes.
Eye Muscle Test
This simple test involves following the light or a doctor’s finger from side-to-side, allows the eye doctor to assess any eye muscle weakness or poor eye coordination which are signs of weakening vision or eye challenges that could servely hinder reading. A paddle may be moved back and fourth and cover one eye at a time. This helps to determine how well your eye muscles are working togeter.
Visual Acuity Test
The eye doctor will ask you to read an eye chart (also called a Snellen chart). This test measures how clearly you currently see.
This eye test will determine if there is a refractive error in how your eyes, and specifically your cornea, handles light passing through the eye. If the light rays do not focus directly on the back of your eye, this refractive error needs to be corrected in order to see clearly. This is where glasses or contact lenses come in as options to correct the vision condition.
Visual Field Test (Perimetry)
This test allows the eye doctor to assess your entire field of vision. For example, you may have issues seeing at the periphery of your field of vision. This and any other odd patterns in your vision abilities can be determined with this test.
Color Vision Testing
Many people who are color blind do not, or did not, realize they were color blind until they were tested. This simple color test will let you know if you have issues identifying colors.
A slit lamp is a microscope with a bright light that allows your eye doctor to examine your eyelids, lashes, cornea, iris, lens and fluid chamber between your cornea and iris and determine if there are any issues.
A retinal examination — sometimes called ophthalmoscopy or funduscopy — allows your eye doctor to assess the back of your eye, including the retina, the optic disk and the underlying layer of blood vessels that nourish the retina. This test allows your eye doctor confirm that this part of your eye is not encountering any issues or is in need of corrective steps.
Screening for Glaucoma
By measuring the fluid pressure inside your eye, your eye doctor can detect glaucoma, a disease that damages the optic nerve. If your eye pressure is higher than average or your optic nerve looks unusual, your doctor may use a pachymeter. This instrument uses sound waves to measure the thickness of your cornea. The most common way of measuring corneal thickness is to put an anesthetic drop in your eye, then place a small probe in contact with the front surface of the eye. The measurement takes seconds. You may need more-specialized tests, depending on your age, medical history and risk of developing eye disease.
