 | Eye exams are one of the most important things you can do to maintain good eye health. Guidelines for how often you should have an exam vary based on your age, family history, and medical conditions you may have. Keep reading below to find out what an eye exam includes and how you should prepare. |
Why are eye exams important?
An eye exam is a critical part of keeping your eyes healthy and preserving your vision. An eye exam can spot problems before they become severe and also allow for prompt treatment. For example, certain eye diseases do not have symptoms in the early stages. According to the National Eye Institute, diabetic retinopathy may not have symptoms at first, but over time, it can lead to vision loss. Early diagnosis can help prevent complications.
What is involved in an eye exam?
Depending on the tests performed, a comprehensive eye exam may take about an hour or possibly a bit more. Usually, the doctor performs a variety of tests to check visual acuity, screen for glaucoma, and view the structures of your eyes.
The exact tests may depend on how frequently you have an eye exam, your age, and risk factors for vision problems. Possible tests include:

- Visual acuity test: A visual acuity test measures how clear or sharp your vision is.
- Slit-lamp test: This test helps your doctor see the structures of your eyes and check for anything abnormal.
- Visual field test: A visual field test allows for evaluation of your side vision and the presence of blind spots, which is one symptom of glaucoma.
- Intraocular pressure measurement: This test measures the pressure which is created by the fluid in the eyes. If the pressure is too high, it can be an indication of glaucoma.
How do you prepare?
There is not a lot of preparation before a comprehensive eye exam, but there are a few things you may want to do. To prepare for an eye exam, it is helpful to consider the following:
Bring your prescription contacts or glasses. If you wear contact lenses or glasses, it is helpful to bring them with you to your appointment. Your ophthalmologist can make sure the prescription is appropriate for your needs.
Bring sunglasses. You may have your eyes dilated with drops as part of the eye exam. If you do, the bright light may cause some mild discomfort. Wearing sunglasses may help. Before your appointment, ask if the doctor will dilate your eyes in case you want to have someone else drive.
Write down questions. Before your exam, consider writing down any questions you may have or areas of concern you want to discuss. Once you are undergoing the exam, you may forget what you wanted to talk about. So, having notes may help.
Bring a list of medications you take. If you are taking any medications, it is useful to have a list. Certain drugs can cause side effects, such as dry eyes. Having information about which medications you take may help your doctor have a clearer picture of what may be contributing to eye issues.
