Understanding Different Types of Eye Exams
Eye exams are necessary if you want to catch eye defects early enough to prevent their progression and complications. Regular exams will give you a chance for early corrections and help you care for your eyes. You can find an ophthalmologist Jacksonville, FL, who can assess your eye vision and determine if you have good eye health. You can benefit from several tests, as each evaluates many different eye conditions you may likely have. You can learn more about some tests from the following discussion.
Eye Muscle Test
The test aims to check and evaluate muscles controlling your eye movement. Your doctor may instruct you to follow the movement of an object as they check how your eyes move. You may have muscle weakness and poor coordination and control that your doctor may observe during this test.
Visual Acuity Test
Your visual acuity reflects your eyes’ ability to discern the shapes and details of things your eyes see. Your doctor uses this test to check how well you can see letters and symbols at a distance. The two common tests under this test are Snellen and random E. during the Snellen test. Your doctor will show you where to stand as you read letters and symbols from a chart as you cover an eye. You read with one closed eye, then do the same with the other eye. On the other hand, a random E test involves identifying the direction of the letter E.
During this test, your doctor passes bent light waves through your lens to check if light rays focus perfectly. You may have a refractive error if these light waves do not focus well, meaning you will require correction. Assessing this error can help your doctor pick out the lens, offering you comfortable and sharp vision. Refraction tests may be useful in diagnosing eye conditions like myopia, hyperopia, astigmatism, and presbyopia. Patients with prescription glasses may require this test every two years to help their doctor with the necessary prescription as their eye changes.
Visual Field Test
The test helps your doctor determine the beginning and end of your side vision and how well you see the objects in your side vision. Visual field tests include confrontational visual field exams, automated perimetry exams, and a tangent screen test. The tests will determine what areas you cannot see, and these locations can help diagnose the eye problem.
Slit Lamp Exam
During this eye exam, your doctor places an instrument where you rest your forehead and chin to help you stay steady during the exam. You may need drops to make abnormalities more visible and wash away your tears. Your doctor will then use a microscope and a slit lamp to examine your eyes.
