Virtual Reality (VR) has seen a rapid rise in popularity, with over 1 million VR headsets shipped in the third quarter of 2017 alone. As more companies enter the market, this number is expected to grow significantly in the near future. However, while VR offers exciting experiences, it’s important to be aware of potential health risks before using these devices—especially for children or those with specific medical conditions.
First and foremost, creating a safe physical environment is crucial. Most VR manufacturers warn that using the headset in a cluttered or crowded space can be dangerous. For example, the HTC Vive’s safety guidelines emphasize that users cannot see their real-world surroundings while wearing the device. This means you should always have someone nearby to help prevent accidents such as tripping, bumping into objects, or even getting seriously hurt. Keep pets, children, and other obstacles away from the VR area to ensure a safe experience.
Another concern is the impact on vision. Some experts, like Professor Martin Banks from the University of California, Berkeley, are worried about how prolonged VR use might affect eye development, potentially leading to issues like myopia or astigmatism. Unlike traditional screens, VR headsets display images that appear far away but are actually very close to the eyes, which can cause eye strain and discomfort. This risk is especially concerning for children, whose visual systems are still developing.
If you experience any physical discomfort during a VR session—such as dizziness, headaches, or nausea—it’s essential to stop immediately. These symptoms are often linked to motion sickness, a condition known as “simulator sickness†that occurs when the brain receives conflicting signals from the eyes and inner ear. Neuroscientist Walter Greenleaf explains that VR can confuse the brain by making the eyes focus on distant images while the body remains stationary. This mismatch can lead to fatigue and long-term effects that are not yet fully understood.
Additionally, loud audio in VR can harm hearing, especially if used for extended periods. It’s important to adjust volume levels so that you can still hear people around you, as excessive noise may cause irreversible damage. Users should also avoid VR if they’re under the influence of alcohol, tired, or experiencing illness, as this can worsen the negative effects.
Certain groups, such as pregnant individuals, elderly people, or those with epilepsy or implanted medical devices, should use VR with caution. If any involuntary muscle movements or balance issues occur during use, the headset should be removed immediately. Google Daydream also advises against using VR when physically unwell, as it may increase the risk of infections or skin irritation from shared devices.
Children require special attention when using VR. Experts recommend limiting screen time and ensuring parental supervision. Research shows that younger children are more likely to confuse virtual experiences with reality, increasing their vulnerability. While some VR content can be educational and beneficial, violent or disturbing material can have lasting psychological effects. Parents should carefully review and test content before allowing children to experience it.
Ultimately, while VR technology brings many benefits, it’s important to use it responsibly. The key lies in balancing its advantages with awareness of potential risks. As the technology continues to evolve, proper guidance and control will determine whether it enhances or harms our lives. Always prioritize safety, monitor usage, and make informed choices to enjoy the full potential of VR without compromising well-being.
