Introduction

A coalition of over 150 healthcare professionals has warned that the amount of time children spend on screens during school lessons may be compromising their long-term physical and developmental health. The open letter, addressed to education and health officials, highlights growing concerns that classroom technology is being used without full understanding of its risks.

What Happened

Clinicians including GPs and paediatricians say tablets and laptops are being deployed in schools without sufficient evidence about their long-term impact. The signatories warn they are already prescribing glasses, hearing aids, and speech therapy for problems they attribute to unintentional overuse in educational settings. A review of 276 global studies involving over 5.4 million participants found myopia rates among children and adolescents climbing from approximately 24% in 1990 to nearly 36% by 2023. The letter notes that nearly one million children in England are exposed to screens for most of their lessons, often exceeding recommended daily limits.

Why This Matters

The clinicians argue that the myopia surge cannot be explained by genetics alone and that school-based screen use is a significant contributing factor. They emphasize that children with special educational needs are disproportionately directed toward screen-based learning, increasing their risk. The letter also warns that without intervention, the compounding health effects could affect an entire generation's educational outcomes and wellbeing. Government officials say they are developing guidance for children aged five to 18, and education unions acknowledge the need for balance, though they stress that technology, when used properly, remains a valuable learning tool.

Key Takeaways

  • Over 150 clinicians have issued an open letter urging a rollback of screen use in English classrooms.
  • A major analysis links rising classroom screen time to a sharp increase in childhood myopia.
  • Nearly one million children are regularly exposed to screens during most lessons.
  • Policy makers and school leaders are being called on to establish evidence-based limits and ensure adequate non-screen time.
  • Parents and educators need clearer guidance and greater support to protect children's eye health and development.

Conclusion

As the debate over classroom technology intensifies, the message from the medical community is clear: safeguarding children's health requires a deliberate rethink of how, when, and why screens are used in schools. Without meaningful policy changes and greater awareness, the long-term consequences for vision and development could become increasingly difficult to reverse.
