5 reasons why eye exams are important
The importance of having a regular eye test goes well beyond just making sure your vision isn't blurry.
Here are five reasons why eye tests are important — and why you should have one to safeguard your health and wellness.
1. Eye tests help children succeed in school.
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.
A regular eye test is the only way to ensure your child is seeing clearly and comfortably 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 an epidemic.
The number of children who are developing shortsightedness (myopia) is growing faster than ever. And more kids are getting short-sighted at a very early age. Between 9 to 12% of kids in ANZ are myopic.
Why is this a big concern?
Children who become short-sighted very early in life tend to experience a increase and progression of shortsightedness 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 a regular eye test is the best way to assess your child's risk of myopia. 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 test.
Too often, parents are led to believe their child is seeing perfectly well because they passed a school vision screening. Or adults think they see perfectly because they pass a number-plate test in their driving lesson.
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 blackboard clearly in the classroom or recognising road signs and other objects from behind the wheel.
Only a comprehensive eye examination by an optometrist (or ophthalmologist) can insure 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.
Of all serious eye diseases, glaucoma is probably the sneakiest. That's because there are no discernible symptoms in most cases of early glaucoma — nothing to alert you that something's going wrong.
People who fail to have a routine eye test and develop glaucoma typically become aware of it only after they’ve sustained a degree of 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 a routine eye test. Vision screenings do little to nothing to identify or prevent glaucoma.
5. Regular eye tests 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 test.
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 examination, your optometrist 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.
Regular eye tests 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 1.2 million people in Australia have diabetes and another half a million have undiagnosed type 2 diabetes. In New Zealand the majority of the 250,000 diabetics are, type two. All these people 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 of Alzheimer's disease that may soon be performed during a comprehensive eye exam.
Don't put it off — schedule an eye exam today
Even if you think you have perfect vision, a regular eye examination can be one of the best things you can do to protect your health and wellness.
Don't dally — find an optometrist and get your eyes checked.
