Eye exams in Charlotte, NC

A complete eye examination does more than determine how clearly you see from a distance and which lens prescription, if necessary, will give you the best possible vision. Your doctor will also run a number of tests to check the health and function of your entire eye.

If you have never had an eye exam or are seeing a new doctor, your doctor or a technician will begin by asking you questions about your medical history, your family’s medical history, and any vision problems you may have. If you wear contact lenses, be sure to bring them with you to your eye exam appointment. They will be checked to make sure that they are the correct prescription, fit, and kind of lens for your eyes.

The importance of a routine eye exam

Whether you're a child or an adult, a comprehensive eye exam is very beneficial. First, an eye exam will determine if your vision prescription has changed and if you need corrective lenses. If you already wear glasses or contact lenses, your eye doctor will decide if your prescription needs to be updated.

An eye exam can also determine if you have more serious eye issues, such as cataracts, glaucoma, or corneal issues. Eye exams can also detect a number of other diseases, including diabetes, hypertension, and cancer.

How is an eye exam performed?

A complete eye examination will include many or all of these painless tests:

Visual acuity test

A visual acuity test measures how well you can see from a distance. Covering one eye at a time, you will look at an eye chart and be asked to identify letters that get smaller as you read farther down the chart.

If your visual acuity test indicates that you need corrective lenses, you will be given a refraction test to determine the correct prescription. Your prescription will be determined by asking you to look through a device called a phoroptor that has many different lenses in it. You will be asked to compare a series of two lens choices and evaluate which lens combination provides you with your best possible vision correction.

Eye muscle test

To test the function of your eye muscles during your eye exam, the doctor or technician will have you follow the movement of an object in many directions, looking for weak muscles or poor control of the muscles that move your eyes.

To test your peripheral vision, which is what you are able to see to the sides of your visual field when you look straight ahead, the doctor or technician will perform a visual field test during your eye exam. You may be asked to cover one eye at a time and, while looking straight ahead, report you can see his or her hand or other object as it moves inward from outside your visual field. Or a computer program may be used to test your visual field. If so, you will look straight ahead into a special device, often a lighted bowl-shaped instrument, and press a button each time you see a flash of light. Your doctor can use your responses to see if there are any blind spots in your visual field.

Overall eye exam

Your doctor will use a slit-lamp microscope to examine the front part of your eye, including the cornea, iris, and lens. You will sit at the slit lamp, which greatly magnifies your eye and shines a bright line of light into it, allowing your doctor to examine your eye closely. Before the test, you may be given eyedrops with fluorescein, an orange dye, to make your cornea easier to see. This dye will wash away naturally.

Glaucoma test

To test for glaucoma, a disease that can cause blindness when too much pressure in your eye damages the optic nerve, the doctor or technician will use a tonometer to measure your intraocular pressure.

Cornea tests

The doctor or technician will give you eye drops containing an anesthetic and fluorescein dye to numb the front surface of your eye and will then use a manual tonometer to gently touch your cornea and measure the force required to flatten it. This procedure is quick and painless, and the anesthetic will wear off in 15 or 20 minutes.

Your doctor may also use pachymetry to measure the thickness of your cornea, which helps evaluate the accuracy of your intraocular pressure measurement. After applying numbing eye drops, ultrasonic waves are used to measure your corneal thickness. This test is also a critical component of evaluating a patient’s candidacy for LASIK surgery.

Retina test

A retinal examination explores the back of your eye including the retina and optic nerve. Your pupils will be dilated with eye drops, which may sting briefly. Retinal examinations usually take about five minutes, but the eye drops will continue to blur your vision for several hours. You may not be able to drive and will be sensitive to bright light, but this is temporary and should resolve in several hours.
