Your doctor will do an eye exam in an office setting during a regular appointment. There may be several tests during this appointment. You may be asked to cover one eye at a time and read a chart. Your doctor may also give you eye drops to dilate your eyes. This increases the size of your pupils. This test allows your doctor to see any signs of damage or disease in your retina or optic nerve.
Seek emergency medical treatment at an emergency room if you experience sudden vision loss. Sudden loss of vision can be a sign of a serious medical problem. Call your eye doctor if you experience sudden blurry vision or flashes of light or if blurry vision interferes with your daily activities. If you have a family history of vision problems, you should have eye exams every year to monitor your eye health and vision.
