Eye Exams: 5 Reasons They Are Important

There's no question eye exams are important to make sure you are seeing normally and as clearly as you can.


But the importance of annual eye exams goes well beyond just making sure your vision isn't blurry. Here are five reasons why eye exams are important — and why you should have annual eye exams to safeguard your health and wellness.

1. Eye exams help children succeed in school.

OK, this one is for you parents. Did you know that 80 percent of what children are expected to learn in and outside the classroom requires good vision? It's true — and that statistic, which has been around for a long time, probably should be revised upward because of the ever-increasing amount of screen time kids are exposed to these days.

An annual eye exam is the only way to insure your child is seeing as clearly and comfortably as possible to succeed in the classroom. It’s also the only way to know for sure if kids are seeing their best for sports and other activities, too.

2. Myopia is becoming epidemic.

The number of children who are developing myopia (nearsightedness) is growing faster than ever. And more and more kids are getting nearsighted at a very early age.

Why is this a big concern?

Children who become nearsighted very early in life tend to experience a worsening and progression of nearsightedness that continues throughout childhood — and this puts them at a significantly greater risk of very serious and potentially sight-threatening eye conditions later in life, including cataracts, glaucoma and retinal detachment.

Scheduling annual eye exams is the best way to assess your child's risk of myopia and detect nearsightedness early on. When detected early, myopia control measures can be taken to slow the progression of myopia and reduce your child’s risk of serious eye problems later in life.

3. Vision screenings are no substitute for an eye exam.

Too often, parents are led to believe their child is seeing perfectly well because she passed a school vision screening. Or adults think they see perfectly because they pass a vision screening at the motor vehicle department. Frequently, neither of these assumptions are correct.

Vision screenings are just that — they screen out individuals who have serious (and usually quite obvious) vision problems. Screenings can identify apparent problems a person might have with specific visual tasks, such as seeing a chalkboard clearly in the classroom or recognizing road signs and other objects from behind the wheel.

Only a comprehensive eye exam by an optometrist or ophthalmologist can ensure your vision is as clear and comfortable as possible — and that you're free from potentially serious eye diseases that don’t have obvious early symptoms, including glaucoma and even eye cancer.

4. Glaucoma.

Okay, I've mentioned glaucoma twice already. So let’s dig into it a little deeper...

Of all serious eye diseases, glaucoma is probably the sneakiest. That's because there are no discernable symptoms in most cases of early glaucoma — nothing to alert you that something's going wrong.

People who fail to have routine eye exams and develop glaucoma typically become aware of it only after they’ve sustained permanent vision loss from the disease. And by that time, controlling glaucoma to prevent additional vision loss can be very difficult. Without successful control with medical treatment and/or glaucoma surgery, the disease can lead to blindness.

Early detection of high eye pressure and other risk factors for glaucoma is possible only with routine eye exams. Vision screenings do little to nothing to identify or prevent glaucoma.

5. Annual eye exams can detect other serious health problems.

Did you know that many people first learn they have serious health conditions such as diabetes, high blood pressure, high cholesterol and even cancer from — yes, you guessed it — a routine eye exam.

Our eyes have been called "the window to our soul." It turns out, they also are often a very effective window to our overall health.

During a comprehensive eye exam, your eye doctor can observe and evaluate the health and condition of the blood vessels in your retina, which are a good predictor of the health of blood vessels throughout your body. Conditions such as diabetes, hypertension and hypercholesterolemia all are visible by changes in the appearance of the retinal blood supply and blood vessels.

Annual eye exams are especially important for anyone with diabetes or who might be at risk for the disease (due to obesity, family history or other reasons). More than 30 million Americans with diabetes and another 84 million who have prediabetes are at risk for developing diabetic eye disease, the leading cause of blindness among adults. In its early stages, diabetic eye disease has no visible symptoms; only a comprehensive eye exam can detect signs of the disease so treatment can begin soon enough to prevent vision loss.

Also, research is advancing to develop an eye test to identify your risk for Alzheimer's disease that may soon be performed during a comprehensive eye exam.
