Nearsightedness

Childhood Myopia Is in Crisis Mode on a Global Scale

When it comes to the prevalence of myopia (nearsightedness), the statistics are staggering. By 2050, nearly half of the world’s population—about 5 billion people—will be myopic. Below are a few useful tips to help you prevent your child from being part of that statistic.

What Is Myopia?

Myopia occurs when the eye elongates, causing light rays to focus in front of the light-sensitive retina rather than directly on it, while looking at something far away. So, people with nearsightedness perceive distant objects as blurred while close-up objects can remain clear.

Myopia tends to develop during childhood, when the eyeballs rapidly grow (along with the rest of the body), mainly between the ages of 8-18. It can worsen slowly or quickly, but it is not simply an inconvenience. People with progressive myopia are more likely to develop serious eye diseases like cataracts, retinal detachment, macular degeneration and glaucoma later in life—conditions which may lead to permanent loss of vision and even blindness.

How To Know Whether Your Child Is Myopic

Below are some telltale signs to watch for:

  • Blurred distance vision – Objects in the distance are blurred; kids may complain that they can’t see the board
  • Headaches – When myopia isn’t corrected, it can cause eye strain and headaches.
  • Head tilting or squinting – If your child squints or tilts his or her head while watching TV, for example, it may be a symptom of myopia.
  • Looking at objects too closely – If you notice your child moving closer to the TV or squinting as they try to see the writing on the board, it may indicate myopia.

What Parents Can Do to Slow Their Child’s Myopia Progression

  • Encourage your child to go outdoors for at least 90 minutes a day, preferably in the sunshine. Studies show that playing outdoors reduces the risk of developing myopia and slows its progression.
  • Limit the amount of time your child spends staring at a screen, reading and doing close work such as homework.
  • When your child uses a digital screen, make sure that it isn’t too close to the face.
  • Teach the 20-20-20 rule: During screen time, take a break every 20 minutes to look at an object across the room or out the window about 20 feet away, for at least 20 seconds.
Frequently Asked Questions with Eric Hammond OD

Q: How is myopia diagnosed?

  • A: Your child’s eye doctor will perform a thorough pediatric eye exam to diagnose myopia, which often includes a visual acuity test, where the eye doctor will use an eye chart made up of letters of varied sizes. If the test results indicate myopia, then the optometrist may shine a light into their eyes and evaluate the reflection off the retina to determine the degree of refractive error for their prescription.

Q: Can myopia lead to blindness?

  • A: High myopia may increase your child’s risk of developing more serious eye conditions later in life, such as cataracts, retinal detachment and glaucoma. Left untreated, high myopia complications can sometimes lead to blindness—which is why routine eye exams are critical.

Can Corneal Refractive Therapy Help with Nearsightedness?

Yes! That’s the short answer to whether corneal refractive therapy, also known as corneal reshaping, can help with myopia. To understand how it works, let’s start with a basic explanation of what causes nearsightedness. Our Cedar Park, Texas , eye doctor explains

What causes nearsightedness?

Nearsightedness, formerly termed myopia, results from an irregularly shaped cornea – either your eye is too long or the cornea is too curved. This adversely affects how light focuses when it enters your eye. To achieve crisp vision, light rays must focus directly on the retina. But if you have nearsightedness, the overly curved structure of your eye disrupts the normal light bending process, and light rays focus at a point in front of the retina.

What is corneal refractive therapy?

Corneal refractive therapy has rapidly become a popular way to correct myopia. This method works by flattening the corneal curvature, thereby improving visual acuity.

You may have heard the term orthokeratology, or ortho-k lenses. Ortho-k is a type of corneal refractive therapy that reshapes the structure of your eye with specially designed gas permeable contact lenses. These highly porous, comfortable contacts are worn while sleeping, and they flatten the front surface of your eye. You remove them upon waking in the morning, but the visual effects remain throughout the next day.

Who’s a candidate for corneal refractive therapy?

In general, people with moderate myopia are good candidates for corneal reshaping. It can be a fantastic option for kids and young adults who don’t like wearing eyeglasses and contact lenses during the day. Corneal refractive therapy can also help if you have mild astigmatism.

How do I start with corneal refractive therapy for my nearsightedness?

First, you need a comprehensive eye exam. For precise vision testing, a thorough inspection of your eye health and to discuss your candidacy for corneal refractive therapy, book an appointment with our eye doctor near me in Cedar Park, Texas .

Nearsightedness & Farsightedness – What Do They Mean?

Your Cedar Park, Texas , eye doctor explains

Nearsightedness and farsightedness, officially termed myopia and hyperopia – respectively, are both refractive vision conditions. That means they are both caused by refractive errors, which are ocular disorders that affect the eye’s ability to properly focus light on the retina. The retina is the membrane that forms the back layer of the eyeball.

Nearsightedness occurs when the light that enters the eye falls short of the retina. Typically, this happens because the eyeball is elongated. As a result, objects in the distance look blurry to people with myopia. However, vision of near objects remains unaffected. Nearsightedness generally develops during childhood, deteriorates during the teenage years, and stabilizes once the person reaches young adulthood.

Farsightedness is basically the opposite of nearsightedness. Usually, it results from having an eyeball that is too short. As a result, light is focused behind the retina instead of directly on it. For people with mild to moderate farsightedness, close objects appear blurred, while objects in the distance are still sharp. However, high amounts of farsightedness may interfere with clear vision at all distances. Children are typically born farsighted, but as they grow and develop, their eyeballs lengthen and the hyperopia decreases.

Diagnosis of myopia and hyperopia – visit an eye doctor near you

While nearsightedness and farsightedness can cause symptoms, such as headaches, squinting, eye strain, and fatigue, these symptoms alone are not sufficient for making a firm diagnosis.

Both of these vision conditions can be detected during an eye exam performed by a qualified eye doctor. As a part of every eye exam, visual acuity will be tested. You will need to read a basic Snellen eye chart, and your eye doctor will test refraction in order to determine your precise vision prescription for glasses or contact lenses.

Treatment for nearsightedness and farsightedness

Corrective eyeglasses and contact lenses are both effective ways to treat nearsightedness and farsightedness. The prescription lenses work by altering the path of light as it bends into the eyes.

When children experience progressive myopia, a variety of methods for myopia control may be suitable. Myopia control treatment can eliminate the need to buy new glasses or contacts yearly, and it can help reduce children’s risk for eye disease in the future. To find out about your child’s candidacy for myopia control, consult a qualified eye doctor and book an eye exam near you.

It is common for myopia and hyperopia to stabilize once people reach their twenties. Once that occurs, refractive laser surgeries – such as LASIK and PRK – become options for treatment. These procedures can permanently resolve nearsightedness and farsightedness by reshaping the cornea to focus light properly on the retina.

Can vision therapy help with nearsightedness and farsightedness?

Clear and fully functional vision depends on more than just sharp visual acuity. Eyesight, the brain, and visual pathways all need to work in sync with each other. When this doesn’t happen, a person can find it difficult to see – even with 20/20 vision. That’s where the role of vision therapy enters the picture.

Vision therapy helps people with particular eye conditions develop the visual skills needed for clear sight, such as:

  • Strabismus (crossed eyes)
  • Amblyopia (lazy eye)
  • Computer vision
  • Traumatic brain injury (TBI)
  • Learning related visual problems (poor eye teaming and focusing)
  • Sports vision improvement

Optic devices and custom-designed exercises are used to strengthen the eye-brain connection, so eye mobility is enhanced. The person learns how to efficiently process visual cues that the eyes send to the brain. Therefore, vision therapy will not help to treat a refractive vision condition, such as nearsightedness and farsightedness.
