Excess of anything is unhealthy. Be it staring at the laptop screen for extended hours, constant mobile screen exposure, or VR for that matter.

Experts from all around the world are fine-tuning VR headsets to counter these issues. A temporary solution is to wear anti-strain specialized lenses if you have to sit through a VR experience for more than a few hours.
