Virtual Reality (VR) has become one of the most exciting technologies in recent years, with numerous industries exploring its potential to transform how we interact with digital environments. From entertainment and education to healthcare and business, VR is seen as a powerful tool that could redefine the future. However, emerging research raises concerns about its impact on children's health, particularly regarding long-term effects that are still not fully understood.
Major technology companies are investing heavily in VR, envisioning it as the next major platform for human-computer interaction. In many people’s minds, VR is set to become an essential part of daily life—whether at home or in professional settings. But according to a study conducted by the University of Leeds in the UK and reported by The Guardian, VR devices may pose certain risks, especially for younger users.
The research was led by Faisal Mushtaq, a human performance technologist, who worked with VR developers to test 20 children aged between eight and twelve. The participants played a 20-minute VR game, fully immersed in a virtual environment. Afterward, researchers observed their visual and motor abilities. Mark Mon-Williams, a cognitive psychology professor at the university, explained that VR presents a 3D world on a 2D screen, which can strain the visual system. While adults may experience temporary discomfort like headaches or eye fatigue, the long-term effects on children remain unknown.
Although the study found no significant decline in children's overall vision, it did reveal that their stereo acuity—meaning their ability to perceive depth—was temporarily affected. Additionally, some children experienced balance issues after playing VR games. These effects, though short-lived, were clearly measurable. "This is the first study to examine the impact of VR on children’s vision and balance," Mushtaq noted. "VR offers incredible possibilities, but we must ensure that children benefit from it safely through solid scientific evidence."
Today, VR is being used in various fields, from gaming and film to medical training. At the University of Leeds, students in the Medical School are using VR to visualize teeth, study tumors, and practice surgical techniques. Despite its promising applications, if VR causes harm, its use will be limited. "You can wear a VR headset and ride a virtual bicycle, or play tennis or golf in a simulated environment," said Mon-Williams. "In the future, VR could replace traditional computer interfaces entirely. Keyboards and mice might become obsolete, and we could interact with screens using hand gestures, like in the movie *Minority Report*."
However, as VR continues to expand, it’s crucial to consider how children interact with these systems. "We need to understand how kids focus on objects and perceive distance in virtual environments," Mon-Williams added. "The key is to address these issues now and design VR devices that don’t cause visual or balance problems."
While VR allows users to break free from physical laws and create new worlds, it also introduces challenges in natural interaction. "Solving these issues might not be complicated, but we must ensure that VR develops responsibly," he concluded. "The way we see and interact with the world is changing rapidly, and the VR industry needs to take this research seriously to make sure it starts on the right foot."
