What Every Mom Needs to Know About Preventing and Managing Myopia in Children

Myopia, also known as near sightedness, is one of the most common vision issues affecting children today. As more children spend time indoors using digital devices for learning and entertainment, the prevalence of myopia has been rising. This vision condition occurs when the eyeball is too long, causing light entering the eye to focus incorrectly, making distant objects appear blurry.

While genetics play a significant role in the development of myopia, environmental factors like prolonged screen time and lack of outdoor activity are contributing to its early onset in children. Understanding the risk factors, prevention techniques, and management strategies is key for parents to safeguard their children's vision.

The Rising Rates of Myopia in Children

In recent years, myopia has become more common in children, with estimates suggesting that nearly 30% of children in the U.S. are affected, and in parts of East Asia, that number jumps to 80-90%. The World Health Organisation (WHO) has even projected that by 2050, half of the world's population will be myopic. Increased time spent indoors, less exposure to natural light, and the rise of screen usage have been linked to this surge in childhood myopia.

Risk Factors for Myopia in Children

Several factors can increase the risk of a child developing myopia:

Genetics: Children with one or both parents who are near sighted are more likely to develop myopia.
Excessive near work: Extended use of digital devices like smartphones, tablets, or computers can lead to eye strain and contribute to myopia progression. Activities that require intense close-up focus, like reading or drawing for long periods without breaks, also pose a risk.
Limited time outdoors: Studies show that children who spend more time outdoors in natural light are less likely to develop myopia. Natural sunlight helps regulate eye growth and reduce the risk of excessive elongation of the eyeball, which causes myopia.
Urban living: Children who grow up in urban environments are more likely to develop myopia, possibly due to less exposure to outdoor activities and more time spent indoors.

Preventing Myopia in Children

While some genetic factors are out of our control, there are steps every mom can take to help reduce the risk of myopia in their children.

Encourage more outdoor play: Research suggests that children who spend at least two hours a day outdoors have a lower risk of developing myopia. Exposure to natural light helps regulate eye growth and can slow the progression of near sightedness.
Limit screen time: Excessive time spent on devices can lead to digital eye strain and worsen vision over time. Encourage regular breaks by following the 20-20-20 rule—every 20 minutes, have your child look at something 20 feet away for 20 seconds. This helps relax their eyes and reduces strain.
Maintain proper lighting: Make sure your child’s study and reading spaces are well-lit. Poor lighting can force the eyes to work harder, increasing the risk of myopia.
Promote balanced activities: Encourage a balance of activities that include both near work (such as reading) and outdoor play. A well-rounded approach can reduce the chances of developing or worsening myopia.
Annual eye exams: Early detection is crucial. Make sure your child has an annual eye exam, especially if there's a family history of myopia. Eye exams can detect early signs of myopia, allowing for timely intervention.

Managing Myopia in Children

If your child has already been diagnosed with myopia, there are several ways to manage the condition and slow its progression.

Corrective lenses: Glasses or contact lenses are the most common way to manage myopia. Ensure that your child has the right prescription and follows the optometrist's guidelines to reduce eye strain.
Orthokeratology (Ortho-K): This treatment involves wearing specially designed rigid contact lenses overnight to temporarily reshape the cornea, improving vision during the day without glasses or contacts. Studies suggest Ortho-K can slow the progression of myopia in children.
Atropine eye drops: Low-dose atropine eye drops have been shown to slow myopia progression in children. These drops are typically prescribed for long-term use and can be combined with other treatments.
Myopia control lenses: New innovations like dual-focus or multifocal contact lenses have been developed to slow the progression of myopia in children. These lenses provide clear vision while reducing the strain on the eye, which helps prevent further elongation of the eyeball.
Vision therapy: In some cases, vision therapy exercises can be recommended to strengthen the eye muscles and improve focusing skills, potentially helping with myopia management.

A Bright Future for Children's Vision

Preventing and managing myopia is essential to preserving your child’s vision and overall quality of life. With early detection, proper management, and simple lifestyle changes, you can help reduce your child's risk of developing myopia or slow its progression if already diagnosed. Encouraging outdoor activity, limiting screen time, and ensuring regular eye exams are foundational steps in protecting their vision for years to come.
