Virtual Reality (VR) has become one of the most exciting and rapidly evolving technologies today. Many industries are exploring its potential, hoping it will revolutionize the way we work, learn, and entertain ourselves. However, recent research suggests that VR may have negative effects on children’s health, especially when used for long periods. While the long-term consequences remain unclear, early findings raise important concerns about its impact on young users.
Tech companies are investing heavily in VR development, envisioning a future where virtual environments replace traditional screens and interfaces. In this imagined world, people could interact with computers through immersive experiences, whether at home or in the workplace. But according to a study published by the University of Leeds, VR devices might pose risks, particularly for children.
The research, led by human performance technologist Faisal Mushaq, involved 20 children aged 8 to 12. They played a 20-minute VR game, fully immersed in a 3D virtual environment. Afterward, researchers tested their vision and balance. Mark Mon-Williams, a cognitive psychology professor at the university, explained that VR displays a 3D world on a 2D screen, which can strain the visual system. While adults may experience headaches or eye fatigue, the long-term effects on children are still unknown.
Although no serious vision decline was observed, the study found that children’s depth perception—how they judge distance—was affected. Additionally, their balance was significantly impaired after using VR. These effects, while temporary, were clearly measurable. "This is the first study to examine how VR impacts children's vision and balance," Mushaq said. "While VR offers incredible opportunities, we must ensure it is safe for kids before it becomes widely adopted."
Many companies are already developing VR games, apps, and educational tools. Some filmmakers are exploring its use in documentaries and animated films, while medical students are using VR to practice procedures, such as examining teeth or studying tumors. Despite its promising applications, if VR causes harm, its use in certain areas may be limited.
Mon-Williams envisions a future where VR replaces traditional computers. "You could wear a VR headset and ride a virtual bicycle, with sensors measuring your effort," he said. "You could play tennis or golf in VR. In the future, VR headsets might replace keyboards and mice, allowing us to type by hand gestures, like in the movie *Minority Report*." But this future depends on ensuring safety, especially for children.
As VR continues to expand, it's not just about better hardware or faster processors—it's also about understanding how children interact with virtual environments. Researchers emphasize the need to study how kids focus, perceive distances, and navigate virtual spaces. The goal is to design VR systems that don’t cause visual or balance issues.
"The beauty of VR is that it frees us from real-world physics," Mon-Williams said. "But it can also create unnatural interactions. Solving these problems might be simple, but it’s crucial to get them right. As VR becomes more integrated into our lives, we must ensure it starts off on the right foot."
