As parents, we track our child’s milestones: their first steps, their first words, the first day of school.

But there is another vital aspect of development that can often be missed until a teacher mentions your child is squinting at the whiteboard. Their vision.

We are seeing a significant rise in myopia, commonly known as short-sightedness. Evidence is mounting that myopia is growing around the world, and it’s estimated that by 2050 more than 50% of the world’s population will have myopia.

While genetics plays a role, our modern, screen-heavy lifestyles are accelerating this disease.

Fortunately, managing myopia isn’t just wearing stronger glasses every year. One of the most powerful, natural tools we have to fight it is right outside your front door.

Myopia, a common eye condition, causes blurred distance vision.

It arises when your eyeball grows too long for the focusing power of the eye – typically this starts in childhood and progresses until maturity. Instead of focusing directly on the retina (the light-sensitive tissue at the back of the eye), light focuses just in front of it. This makes distant objects look blurry while close-up things stay clear.

Myopia control aims to slow down this elongation during childhood and teenage years. Higher levels of short-sightedness not only require thicker lenses; it increases the risk of serious eye conditions later in life, such as retinal detachment and glaucoma.

We use clinical interventions including contact lenses, orthokeratology (night-time lenses), and medicated eye drops, but lifestyle changes can be the foundation of effective management.

If you want to support your child’s eye health, encourage more green time, less screen time.

Research consistently shows that children who spend more time outdoors have a lower risk of developing myopia, and those who already have it may slow the progression of the disease.

How exactly does sunshine protect young eyes?

Two main factors are at play:

1. The Power of Bright Light:
Exposure to the sun’s rays is believed to stimulate the release of dopamine in the retina. This stops the eyeball from growing elongated and distorting light entering the eye, allowing the eyeball to maintain its correct, rounded shape. Indoor lighting cannot replicate natural daylight that is required to trigger this process.

2. The “Horizon” Effect:
When children play outside, their eyes naturally shift between looking at a ball nearby, a tree in the distance, and the horizon. This variety relaxes the focusing muscles inside the eye. Indoors, their vision is usually locked into a short, fixed distance—whether it’s a phone, tablet, book, or a television.

We recommend spending time outdoors as often as possible. It doesn’t have to be structured sport, it could simply be a walk around the block, playing in the park, or even having afternoon tea in the backyard, all these activities count toward protecting your child’s vision.

Myopia can also impact how our eyes behave after dark, sometimes overlapping with a symptom known as nyctalopia, or night blindness.

Night blindness isn’t actually a disease, but rather a symptom of an underlying issue. It means your eyes are struggling to adapt to low-light conditions, making tasks like driving at night or walking through a dimly lit room difficult.

In the dark, your pupils dilate to let in more light. This can amplify existing focusing errors and peripheral distortions, making your vision blurriness worse in low light.

And if you have a high degree of myopia, this can cause structural stretching of the retina which can impact the health of the “rods” in your eyes. Rods are photoreceptor cells in your retina that are responsible for our night and peripheral vision. If these cells aren’t functioning optimally, navigating the dark becomes a challenge.

Balancing screen time with regular outdoor time gives your child’s eyes the best possible start.

Because myopia progresses more rapidly during the early years of life, detecting the problem as early as possible can make quality of life better for your child.

Regular eye checks mean that your optometrist can track the changes in vision and provide solutions before it impacts day-to-day vision.

If you have noticed your child squinting, complaining of headaches, or struggling to see the TV, it is time to look closer.
