Is VR healthy? Can you get hurt while using it?
The general consensus is that yes, it’s totally safe to use, especially for adults whose eyes have already stopped developing and who don't really get motion sick. Whether it’s safe for kids ages 13 and under remains a subject of debate, but most companies recommend limited use for the age group with plenty of breaks.
In fact, even for adults just getting into the medium, we recommend slowly getting acclimated. Putting the headset on for a few minutes at a time then taking it off, just to get your eyes used to having a screen that close.
That said, eye fatigue is probably the most ‘dangerous’ part of VR. Wearing a headset for an hour or more does put some strain on your eyes and it can cause headaches if you’re not properly hydrated or motion sickness if the content you’re watching moves in a way that feels unnatural to your body. Neither is permanent, though, and both should subside fairly quickly once you take the headset off.
Just as important as taking breaks is clearing the space around you while using a VR headset – unless you’re using the passthrough cameras on the headset, there’s no way to see what’s going on around you so it’s incredibly easy to trip and fall if you’re playing in a furnished room. Most PC headsets will ask you to setup boundaries before you start playing that will prevent you from walking into anything but usually the more empty the playspace is, the safer it’s going to be for you.
