With the popularity of virtual reality increasing every day, the parents and teachers are concerned about its impact on the youngster’s eye health. One of the biggest complains of VR users is the motion sickness or nausea that comes after even mild usage of these headsets.
Are there any side effects to using these headsets? Can it cause any permanent damage to your eyes? We will try to answer these concerns in this article.
Improper use of VR headsets may cause permanent damage to your eyes. But by following the safety rules suggested by the manufacturer, the probability of risk can be severely reduced.
The earliest version of VR devices caused quite a few health problems. But with the advances being made in the technology and continued testing on health parameters has allowed the manufacturers to reduce the occurrence of such problems to a great degree. Many universities are conducting research to assess the long-term impact of extended usage of VR tools.
Here are some problems being faced by the current generation of VR headsets and suggested safety measure to overcome the problems.
- HEV High Energy Visible light
The bright pictures on VR screens send too much light into eyes and may cause permanent damage to the iris. Keeping the brightness and contrast low will reduce the amount of light entering your eye and thus prevent eye injury.
- Duration of play
The duration of exposure is another factor that can determine how much your eyes are impacted. Sticking to a duration of 30 minutes or less will ensure your eyes do not suffer from any long-term effects
- Light frequencies
Blue light is found to be particularly harmful to human eyes. If the screen or lens produces too much blue light, it will strain the eye and the user will find it very hard to sleep. Good manufacturers use the right type of lens to remove the blue light effect from their VR headsets. So it is important to research your VR headset and avoid buying cheap Chinese knockoffs which may not take care of such issues.
- Focus problem
The human eye’s ability to focus on multiple things at the same time cannot be replicated in the virtual world. So things may appear fuzzy at times and may even cause vertigo or nausea.
When you get a new headset, spend some time to set it up correctly to your eye requirements. Some headsets have the flexibility to adjust the lens within so that you can play without prescription glasses. Set it up correctly and you can avoid the fuzziness and even nausea problem that can emerge due to out-of-focus images.
- Age restrictions
Some VR companies discourage VR headsets for kids. HTC Vive has specified their headsets do not suit children. Oculus suggests their devices for children above the age of 13. Google says children can use their cardboard VR set only under adult supervision.
By taking these precautions, it is easy to avoid any permanent damage to your eye while using VR headsets.
