Why Eye Exams Are Important
Routine eye exams are key to keeping your eyes healthy because they help catch problems early when it’s easiest to treat them. Diseases like glaucoma and diabetic eye disease don’t have obvious symptoms in their early stages, but that’s when it’s easiest to start treatment and prevent vision loss. An eye examination by a doctor is usually the only way to catch these diseases early on. Eye exams are also important for keeping your glasses or contact lens prescription current. If your vision has changed since you last got eyewear, it may no longer be serving you well. That can lead to headaches, difficulty reading, and potentially dangerous situations while driving.
Kids should have their vision checked at least once every year or two, as should adults who wear glasses or contact lenses or have a family history of eye disease. Adults with healthy eyes and no vision problems can have their eyes checked less frequently.
What Eye Exams Entail
Anyone who’s been to an eye doctor likely remembers reading through a list of progressively smaller letters, but eye exams are about far more than this visual acuity test. They are done to detect eye problems early on when it’s easiest to treat them. To do this, an eye exam will likely include a number of the following components:
- Medical history: Your ophthalmologist or optometrist will ask you about your medical history, family medical history, and any problems you’ve noticed with your vision.
- Visual acuity test: To measure your vision, your doctor will have you identify letters printed on a chart, with the letters getting progressively smaller.
- Eye pressure test: This test helps to detect glaucoma, a disease that damages the optic nerve. During this test, the doctor may put numbing drops in your eyes so you don’t feel it.
- Dilation: To look more closely inside your eyes, the doctor will usually dilate your eyes with eye drops. They will then use lights to examine the front and inside of the eye for any potential problems.
- Color vision test: If you have difficulty telling colors apart from one another, you may have poor color vision. An eye doctor can test for this by showing you patterns of multicolored dots, asking you to pick out numbers and shapes.
Following the exam, your doctor will discuss any results with you and update your glasses or contact lens prescription, if necessary.
