Child Myopia Exploration: An Uncommon Perspective on Far-Sighted Developments in Children
Stepping into the future: Demystifying the rise of nearsightedness
With smartphones becoming an integral part of our lives, the rise of nearsightedness in children has become a growing concern.
Today, donning glasses is no longer a rare sight on the playground. Statistics show that about 15% of kids in this country are nearsighted by the end of elementary school. And experts predict this number is set to climb due to extensive smartphone usage. Unfortunately, this trend isn't limited to our shores—rising nearsightedness is already causing alarm in other parts of the world, notably in Asian metropolises, where more than 80% of young people are nearsighted. This is problematic since severe nearsightedness can lead to serious eye diseases, such as glaucoma.
But parents don't have to stand idly by—there are measures they can take to manage their children's nearsightedness. Stephan Degle, an optician and optometrist from the Verein Kuratorium Gutes Sehen, explains, "Nearsightedness in children can't be stopped, but in most cases, it can be slowed down."
The key factors behind a child becoming nearsighted are genetic predisposition and visual habits. The misconception that too much reading ruins the eyes is actually rooted in truth—but it's digital devices, particularly smartphones, that wreak the most havoc. As eye doctor Norbert Pfeiffer elucidates, our visual system is designed for distance, a capability crucial for Stone Age humans when spotting game from afar.
Nearsightedness arises when the eye adapts to its near workload. To focus on objects up close, the lens' suspending muscle contracts, making the lens spherical. This process strains the eye, prompting it to adapt and grow longer over time, which makes it easier to see nearby objects but compromises vision for distance— Resulting in nearsightedness. The closer the work distance, the more pronounced the effect. Smartphones, for instance, are especially problematic since the eye must focus on a very small distance.
Recent research reveals that children's nearsightedness increases as they spend more time in front of screens, especially when surpassing the one-hour mark daily. To slow down this development, Pfeiffer advises limiting screen time and encouraging children to spend at least two hours outside each day. Evidently, the benefits of this simple behavioral measure extend beyond preventing nearsightedness, as spending time outdoors may facilitate light-triggered dopamine release, which is known to inhibit the growth of the eyeball.
In addition to these lifestyle modifications, other interventions such as medications, special glasses, and contact lenses can potentially hinder the growth of the eyeball. Atropine eye drops, for example, are used to slow the progression of myopia, although the exact mechanism behind this pharmacological approach remains unclear. It's essential to remember that treatment effectiveness remains contingent on consistent use—"The treatment only works as long as it's used," says Pfeiffer.
Special glasses designed to correct myopia and simultaneously slow down its progression are also available on the market. Multifocal lenses, for instance, create a second image plane to prevent excessive eye elongation. While their effectiveness is still uncertain, as a recent meta-study by the Cochrane research network suggests, they hold promise for reducing myopia severity.
Ultimately, a personalized approach, entailing thorough investigation and assessment by an eye care professional, is vital to determining the most suitable solution for preventing or slowing the progression of nearsightedness. After all, child development is no one-size-fits-all proposition.

- The increasing number of children with nearsightedness can be linked to extensive medical-conditions like excessive smartphone usage, which places strain on the eye and encourages eye-health issues.
- Apart from limiting screen time, health-and-wellness measures such as spending at least two hours daily engaged in fitness-and-exercise activities outdoors may aid in preventing or slowing nearsightedness.
- Mental-health can also play a role in eye-health development since spending time outdoors is thought to promote dopamine release, potentially impacting skin-conditions like the growth of the eyeball.
- Beyond lifestyle modifications, nutritional approaches such as the use of Atropine eye drops or special glasses engineered to slow myopia progression may provide additional interventions for managing nearsightedness in children.
