Alarming Rise: Global Myopia Epidemic Threatens Youth Vision
(upbeat music) - Welcome to "Listen To." This is Ted. The news was published on Tuesday, September 24th. Today we're joined by Eric and Kate to discuss a pressing health issue. Let's dive right in. Today we're discussing the alarming rise in shortsightedness among children and teens globally. A recent study projects that by 2050, over 740 million cases will exist worldwide. Let's start with the current prevalence. Eric, what are the numbers telling us? - Well, Ted, the numbers are downright shocking. We've seen a tripling in overall prevalence between 1990 and 2023. It's gone from 24% in the 90s to a whopping 36% in recent years. That's one in every three kids. It's like we're watching a slow motion epidemic unfold before our eyes. - While those numbers are concerning, we need to consider the positive aspects. This increase in diagnosis means more children are getting the care they need. It's not- - Care is important, but prevention is key. The sharp increase to 30% in 2011, 19, and then to 36% in 2020, 23 is alarming. We need to address the root causes. We can't just slap glasses on kids and call it a day. Let's not panic. Medical advancements mean we can manage myopia better than ever before. The increase in diagnosis is a sign of better healthcare access. We're catching- - Interesting points from both of you. Now let's talk about the factors influencing prevalence. Kate, what groups seem to be most affected? - The study shows higher prevalence in East Asia, urban areas among females, and in adolescents. It's crucial we understand these demographics to target interventions effectively. For instance, in East Asia, the prevalence is a staggering 35%. That's more than one in three kids. - While demographics are important, we can't ignore the role of lifestyle choices. The study suggests a link between education levels and myopia. We need to question our current educational practices. - Education isn't the enemy here. We should focus on balancing screen time with outdoor activities, not pointing fingers at our school systems. Kids need to learn, and it's not about blame, it's about facts. The study clearly shows a 46% prevalence in those with high school education. We can't ignore this correlation. That's nearly half of all- - Correlation doesn't equal causation. These numbers might simply reflect better access to eye care in more educated populations. We can't jump to conclusions without- - Let's look at this issue in a historical context. Can you think of a similar health trend we've seen in the past? - This reminds me of the obesity epidemic that began in the late 20th century. Like myopia, it's linked to lifestyle changes and modernization. We saw a similar rapid increase that caught us off guard. It's a wake-up call that our modern lifestyles can have unexpected health consequences. - That's an exaggeration. Myopia is far more manageable than obesity and doesn't have the same health implications. We're talking about vision correction, not an exaggeration. Both conditions increased rapidly due to societal changes. In the 1960s, only 13% of U.S. adults were obese. By 2008, it was 34%. That's a similar tripling we're seeing with myopia. - But obesity has clear links to diet and exercise. Myopia is more complex and often genetic. We can't draw such simple parallels. It's like comparing apples and oranges. - The complexity is similar. Both involve a mix of genetic predisposition and environmental factors. Just as we had to rethink food policies for obesity, we need to rethink screen time and outdoor activities for myopia. We can't stick-- - But the obesity epidemic led to fat shaming and discrimination. We can't risk stigmatizing children who need glasses. That could have serious psychological impacts. - Interesting comparison. Now, how do you think the COVID-19 pandemic has impacted this trend? - The pandemic likely accelerated the trend due to increased screen time during lockdowns, but it also raised awareness about eye health. Kids were suddenly spending hours on Zoom for school and parents started noticing vision issues they might have missed before. It's a double-edged sword. - I agree it accelerated the trend, but this is precisely why we need to be concerned. The sharp increase post 2020 shows how vulnerable our children's eyes are to lifestyle changes. We've essentially conducted a global experiment on our kids. - But we adapted quickly with online learning. This shows we can find solutions to manage eye health even in challenging circumstances. We developed new technologies, new teaching methods. - Adaptation isn't enough. We need prevention. The pandemic has shown us the real cost of our screen-dependent lifestyles. We can't just keep reacting. We need to be proactive about-- - Looking ahead, the study projects some concerning trends. Eric, how do you see this situation unfolding? - I see a crisis in the making. With projections of 40% global prevalence by 2050, we're looking at a future where nearly half of all young people could be myopic. This will strain healthcare systems and potentially impact workforce productivity. Imagine a world where half the population needs vision correction just to function. - That's an overly pessimistic view. - I see a future where we've adapted to this change. Improved treatments, better screen technologies and more awareness will help us manage this effectively. We're not-- - Management isn't enough. We need to prevent this rise. The projected 69% prevalence in Asia by 2050 is staggering. We're talking about fundamental changes to how children live and learn. We can't just accept that too-- - But look at the innovations we're already seeing. Special glasses, contact lenses, even eye drops that can slow myopia progression. The future isn't as bleak as you paint it. Sciences make-- - Both of you make interesting points. Now let's consider policy implications. What action should governments and schools take? - We need strict policies on screen time in schools and at home, mandatory outdoor time for children, redesigned classrooms with more natural light and public health campaigns about eye health are crucial. We need to treat this like the public health crisis it is, it's time for bold action. - Those are extreme measures. We should focus on education and providing resources. Teach children about eye health, provide regular checkups and support families in balancing screen use. We don't need to-- - Education isn't enough. The numbers show we need drastic action. Countries like Singapore have national myopia prevention programs. We need similar initiatives globally. We can't just hope this-- - But heavy-handed policies could backfire. We need to empower families to make informed choices, not dictate their lifestyle. People don't respond well to being told what to do. - Informed choices haven't worked so far. The rising numbers prove we need stronger intervention. We can't keep doing the same thing and expect different results. It's time to-- - Intervention, yes. But not at the cost of personal freedom. We can address this issue without becoming a nanny state. There's a balance to be struck here. - Well, it's clear this issue sparks passionate debate. While Eric and Kate may disagree on the approach, they both acknowledge the seriousness of rising myopia rates. As we wrap up, it's evident that addressing this growing health concern will require a multifaceted approach, balancing prevention, treatment and policy. Thank you both for your insights and thank you listeners for tuning in to listen to.
