Are you due for a comprehensive eye exam? It is recommended that you have a comprehensive eye exam every year to assess the health of your eyes. If you wear glasses or contacts, you may already have an eye exam every year to check your prescription and possibly order new glasses or contacts. But even if you have perfect vision, you should still have a comprehensive eye exam every year.
What exactly does a comprehensive eye exam entail? Here’s what you can expect.
A Visual Acuity Test
One of the first things you will be asked to do during a comprehensive eye exam is to read a chart on the wall. The chart contains random letters in rows in descending order from largest to smallest. You will be asked to stand a specific distance away from the chart and read the smallest row you are able to read. This gives a basic assessment of your far sight. You will also be handed a card with small print to read, which assesses your near sight.
Eye Focus and Eye Teaming Tests
You will also be asked to cover one eye at a time and read the same wall chart. This will determine how well your eyes work independently of each other. It also indicates whether or not one eye is significantly better or worse than the other.
Depth Perception Test
Your depth perception will also be tested during a comprehensive eye exam. A depth perception test could be performed in a variety of ways, but it typically involves focusing on an object that is far away and then an object that is closer. Your ability to change focus between the two objects will determine whether or not there are any depth perception issues.
Ocular Motility Test
Ocular motility refers to the movement of your eyes. This is tested very simply by asking you to look in different directions, such as up, down, left, and right. Your optometrist will be looking to see that your eyes move in the direction you are looking and if both eyes move together.
Slit Lamp Test
This test allows the optometrist to examine the shape of your eye and look for any abnormalities. It is called a slit lamp test because a bright light passes through a narrow slit in order to shine a very thin sheet of high intensity light into the eye. This test can also identify cataracts, macular degeneration, and other potential eye health issues.
This test was once performed by blowing a quick puff of air at the eye to check the pressure within the eyeball. Now this test is performed by an instrument that gently pushes on the eye to check the pressure. Although it makes actual contact with the eye, it is much less invasive and startling than the previous air puff test. The purpose of assessing eye pressure is to check for the presence of glaucoma.
Your optometrist will place drops in your eyes that will dilate your pupils. This allows them to look into your eyes to check the health and connectivity of your retina. The retina contains nerves that connect the eyes to the brain. This is how the eye sends images to the brain in order for the brain to make sense of what the eyes see. A variety of issues can occur in the retina that can affect your vision, and pupil dilation makes it easier to see if there are any concerns.
Retinal mapping is an optional test that many optometrists highly recommend. Retinal mapping involves making digital images of the back of the eye. This test may or may not require pupil dilation and allows the optometrist to check the health of your retina. It is not typically covered by insurance however, which causes many patients to opt out of this highly beneficial test.
