Think you don't need to see an eye doctor because your vision is fine? Think again.
Eye exams aren’t only for people with poor vision. They're an important way of detecting eye problems before you have symptoms. Eye doctors can also catch other health problems -- like diabetes -- early.
It's important to keep in mind that most people with open-angle glaucoma, the most common type, have no symptoms until they have lost a significant amount of vision.
The condition can be prevented, but once vision is lost, it is irreversible. That is why it's very important to get regular exams with an eye doctor, particularly if there is a family history of glaucoma.
Symptoms of glaucoma vary, depending on its type.
If it's been more than a few years since your last appointment -- or if you've never had one -- it's time to schedule a trip to the eye doctor.
What to Bring to the Eye Doctor
Your glasses or contacts (if you wear them)
You may want to not wear your contacts for a few days prior to the visit to allow for more precise measurements -- ask the doctor’s office when you make the appointment
A list of any health conditions or allergies
A list of all medications and supplements that you take
A list of any specific questions you have about your eye health
Your insurance information -- most policies will cover some eye care
What Will Happen During an Eye Appointment?
After filling out paperwork, you'll go to the examining room to meet the doctor. The exact type of exam will vary. But here are some things you can expect.
Patient history. Your doctor will ask about your general health and any family history of eye diseases.
Vision testing. Your doctor will check your close and distance vision. You'll read from charts of random letters. Your doctor may also test other aspects of your vision -- such as your ability to see in 3D, your peripheral (side) vision, and color perception.
Tonometry. Your doctor will test the pressure in your eye with a puff of air or a device called a tonometer. Tonometry tests for glaucoma.
Eye exam. Your doctor will closely examine the different parts of your eye. You may need drops to dilate your eyes -- to make the pupils open wide. This will help your doctor get a clear view of the inside of your eye. Dilation makes your eyes sensitive to light for a few hours. You'll need to wear sunglasses until the drops wear off. You may need someone to drive you home.
Other tests. Depending on your health and age, you may need other further tests or exams.
Eye exams can sometimes detect early signs of glaucoma, diabetes, high blood pressure, and arthritis. If the doctor finds anything unusual, you may need a follow-up with your regular doctor or a specialist.
How long will it take? If it's your first visit to your new eye doctor, allow an hour or two. That includes time to get examined and to get fitted for a prescription if you need it. Later appointments won't take as much time.
Before You Leave the Office
