Sony has updated its PSVR FAQ today. One of the big questions addressed by the update is the subject of bright light or light reflected off shiny surfaces. Apparently intense light can interfere with the tracking of the LEDs on the headset. Ambient lighting will generally not affect PS VR gameplay. Bright light sources directly behind the person using PS VR, lights coming in from windows and room lights, and lights reflecting off mirrors can interfere with the PS Camera and interrupt the tracking of the LED lights on the headset. It is recommended to eliminate bright light sources behind the PS VR player.
