In a world increasingly dominated by screens, the vision of our children hangs in the balance. Myopia, or nearsightedness, is not just a minor inconvenience; it’s a growing epidemic. The statistics are staggering. In Singapore, 65% of children at age 12 are myopic. This figure climbs to 83% among young adults. Alarmingly, 20% of these children suffer from high myopia, a condition that can lead to severe complications like retinal detachment and blindness.

High myopia is defined as a refractive error of -6 diopters or worse. To put it simply, this means that if your child’s vision is worse than 600 degrees, they fall into this dangerous category. While glasses and contact lenses can correct vision, they do not address the underlying risks associated with high myopia. The real danger lies in the potential for serious eye diseases in adulthood, including myopic macular degeneration, cataracts, and glaucoma.

So, what’s causing this surge in myopia? The culprits are many. Increased screen time from handheld devices, computers, and tablets is a significant factor. Children are spending more time indoors, glued to screens, and less time outside. Genetics also plays a role; children with myopic parents are at a higher risk. However, the myth that reading in dim light or sitting too close to the TV causes myopia has been debunked.

The onset of myopia can begin as early as preschool. Many children are diagnosed during routine school health screenings. In fact, eye clinics are seeing more young patients with reduced visual acuity at earlier ages. This trend is alarming.

But why does myopia lead to retinal detachment? Imagine your eye as a balloon. In a healthy eye, the retina is snug against the inner wall. In a myopic eye, the balloon stretches, thinning the retina. If the stretching continues, the retina can tear, leading to detachment. This is a serious condition that can result in permanent vision loss if not treated promptly.

Parents often wonder if myopia stabilizes as children grow. While many children experience a stabilization of their vision in late adolescence, some continue to progress into their twenties. Lifestyle factors, visual demands, and underlying eye conditions can all contribute to this ongoing progression.

Recognizing the signs of retinal detachment is crucial. If your child complains of floaters, flashes of light, or a shadow obscuring their vision, seek medical attention immediately. Time is of the essence; untreated retinal detachment can lead to blindness within days.

Fortunately, there are ways to combat the rise of myopia. Lifestyle changes can make a significant difference. Encourage your child to take breaks from screens. The 20-20-20 rule is a good guideline: every 20 minutes, look at something 20 feet away for at least 20 seconds. Outdoor time is equally important; aim for at least two hours a day.

For those already diagnosed with myopia, specialized contact lenses and treatments are available. Low-dose atropine eye drops have shown promise in slowing myopia progression. Additionally, certain lenses, like HALT and DIMS, can help control myopia in children. These lenses create defocused areas in the peripheral retina, signaling the eye to slow its growth.

Orthokeratology, or ortho-k, is another innovative approach. This method uses specially designed contact lenses worn overnight to reshape the cornea temporarily. When the lenses are removed, children can enjoy clear vision throughout the day without the need for glasses.

As parents, it’s essential to be proactive. Regular eye exams are crucial, especially for children with a family history of myopia. Consult with an optometrist about the best options for your child.

The myopia epidemic is not just a personal issue; it’s a community challenge. Schools, healthcare providers, and parents must work together to raise awareness. Public health campaigns can educate families about the importance of eye health and the risks associated with myopia.

In conclusion, the rising tide of myopia demands our attention. It’s a call to action for parents, educators, and healthcare professionals. By understanding the risks and taking proactive steps, we can protect our children’s vision for the future. Let’s not wait until it’s too late. The time to act is now.
