WHAT TO EXPECT DURING YOUR EYE EXAM
Dr. Johnson uses a variety of tests and procedures during your eye exam to examine your eyes, ranging from simple to complex. From having you read an eye chart to using a high-powered retinal camera to visualize the tiny structures inside of your eyes, all of these tests are important to the process of accurately evaluating the health of your eyes and recommending an accurate prescription. In order to fully evaluate your vision and the health of your eyes, you should expect to spend about an hour for your eye exam with our eye doctor.
Dr. Johnson will most likely use an autorefractor as a starting point in determining your prescription in the eye exam. With this piece of equipment, you will be asked to rest your face in a chin rest and focus on a distant image inside of the machine. An autorefractor determines the lens power required by your eye to accurately focus light on your retina, giving Dr. Johnson a baseline prescription in an accurate & time-saving manner in the eye exam. This is especially useful in certain cases where a patient can not sit still, pay attention, or interact with the eye doctor adequately for the amount of time necessary for a manual refraction during the eye exam.
A refraction is the test that Dr. Johnson uses to determine your exact eyeglass prescription during the eye exam. During this manual refraction, she’ll put an instrument called a phoropter in front of your eyes. You will be asked to view an eye chart or other testing image through a series of lenses. Dr. Johnson will ask you about how you perceive the images through each lens. Based on your answers, she will be able to fine tune the lens power until a final prescription is reached.
When it comes time to in the eye exam to examine the health of your eyes, Dr. Johnson typically uses a slit lamp, also known as a biomicroscope, to get a highly magnified view of the structures of your eye, allowing her to detect any signs of infection or disease.
To obtain a better view of your eye’s internal structures, Dr. Johnson may need to enlarge your pupils with the use of dilating drops during the eye exam. The drops usually take about 20 to 30 minutes to start working. Once they do, she’ll be able to use a variety of instruments to look through your enlarged pupil. As a result of pupil dilation, which usually lasts for 4-6 hours afterward, you may experience sensitivity to light and reduced visual clarity at near. It is recommended that you bring sunglasses to wear after the eye exam and don’t plan on doing any up-close work immediately after your dilation.
