The Surge in Myopia Among Children Post-COVID-19

The COVID-19 pandemic has reshaped many aspects of daily life, from education and social interactions to health and well-being. Among the significant health concerns that have emerged in recent years, a sharp rise in myopia (nearsightedness) among children has become a major issue worldwide. As children spent more time indoors and engaged in prolonged screen exposure due to online learning, their vision was impacted significantly.

Dr Shaun Segal, a leading expert in pediatric eye health, has been closely monitoring this concerning trend. He emphasizes that the increase in myopia cases among children is directly linked to lifestyle changes caused by the pandemic, particularly reduced outdoor activities and excessive screen time. This blog will explore the causes behind the surge in myopia, its long-term implications, and how parents can take proactive steps to protect their children’s vision.

Understanding Myopia and Its Link to COVID-19

Myopia, or nearsightedness, is a condition where distant objects appear blurry while close-up objects remain clear. This occurs when the eye grows too long, causing light to focus in front of the retina rather than directly on it. Myopia has been on the rise globally for decades, but the COVID-19 pandemic has significantly accelerated its progression in children.

Dr Shaun Segal explains that before the pandemic, children typically balanced screen time with outdoor play and in-person learning. However, the lockdowns and school closures forced children to rely on digital devices for education, entertainment, and communication. This drastic shift resulted in prolonged near work, such as reading and screen use, which increased strain on young eyes and contributed to myopia development.

Key Factors Driving the Surge in Myopia

Dr Shaun Segal highlights several major factors that contributed to the post-pandemic increase in myopia among children:

1. Increased Screen Time

One of the most significant changes during the pandemic was the sharp increase in screen exposure. Remote learning required children to spend hours each day on digital devices, leading to excessive near work. Additionally, reduced recreational activities meant that children turned to smartphones, tablets, and gaming consoles for entertainment, further straining their vision.

2. Reduced Outdoor Time

Spending time outdoors is known to slow myopia progression due to exposure to natural light and distant focusing. Dr Shaun Segal points out that during the lockdowns, children had limited opportunities to play outside or engage in physical activities. This lack of outdoor exposure disrupted a key protective factor against myopia.

3. Poor Visual Habits

With increased screen time came poor posture, reduced blinking rates, and prolonged focus on close-up screens. Many children used devices in dim lighting, at close distances, or for extended periods without breaks. These habits placed additional stress on their developing eyes and accelerated the onset of myopia.

4. Delayed Eye Check-Ups

During the height of the pandemic, routine medical appointments, including eye exams, were postponed or canceled. Dr Shaun Segal notes that many children who had early signs of myopia were not diagnosed or treated in time, allowing their condition to progress unchecked.

The Long-Term Implications of Myopia in Children

While mild myopia is manageable with corrective lenses, high myopia poses significant risks for long-term eye health. Dr Shaun Segal warns that severe myopia increases the likelihood of complications such as:

• Retinal Detachment – A condition where the retina separates from the eye, potentially leading to vision loss.
• Glaucoma – Increased eye pressure that can damage the optic nerve and cause blindness if untreated.
• Macular Degeneration – Deterioration of the central part of the retina, impacting sharp vision.
• Cataracts – A higher risk of early cataract formation compared to non-myopic individuals.

Given these risks, it is crucial for parents to take early action in managing myopia progression in their children.

Preventing and Managing Myopia: Expert Advice from Dr Shaun Segal

While the increase in myopia cases is concerning, there are several effective ways to slow its progression and protect children’s eye health. Dr Shaun Segal offers the following recommendations:

1. Encourage More Outdoor Play

One of the best ways to prevent myopia is to ensure that children spend at least 2 hours outdoors each day. Exposure to natural light helps regulate eye growth and reduces the risk of myopia progression. Activities such as playing in the park, riding a bike, or engaging in outdoor sports can significantly benefit vision health.

2. Follow the 20-20-20 Rule

Dr Shaun Segal advises that children should practice the 20-20-20 rule when using screens: Every 20 minutes, take a 20-second break and look at something 20 feet away. This simple habit reduces eye strain and allows the eyes to relax.

3. Limit Screen Time and Take Frequent Breaks

Parents should set limits on recreational screen time, ensuring that children engage in a balance of activities that do not solely rely on digital devices. Encouraging offline hobbies such as reading physical books, drawing, or playing board games can reduce excessive near work.

4. Maintain Proper Screen Distance and Lighting

Children should hold digital devices at least 18-24 inches away from their eyes and avoid using screens in dark environments. Dr Shaun Segal also recommends adjusting screen brightness and contrast to reduce glare.

5. Prioritize Regular Eye Exams

Early detection of myopia is essential for effective management. Dr Shaun Segal stresses the importance of annual eye check-ups, especially for children who show early signs of myopia, such as squinting, headaches, or difficulty seeing distant objects. Early intervention can prevent myopia from worsening.

6. Consider Myopia Control Treatments

For children diagnosed with progressive myopia, specialized treatments can help slow down its advancement. Dr Shaun Segal mentions that options such as orthokeratology (Ortho-K) lenses, atropine eye drops, and myopia control glasses have shown promising results in controlling myopia progression.

The post-COVID-19 surge in myopia among children is a pressing issue that requires immediate attention. The combination of increased screen time, reduced outdoor exposure, and poor visual habits has contributed to a significant rise in nearsightedness. However, with proper precautions and early intervention, myopia progression can be slowed, reducing the risk of long-term complications.

Dr Shaun Segal emphasizes that parents play a crucial role in protecting their children’s vision by encouraging healthy habits, limiting screen time, and scheduling regular eye exams. By taking proactive measures today, we can help ensure that children maintain healthy eyesight for years to come.
