With only some days left until the PSVR release I think this is the perfect moment to warn future owners that VR headsets do have a natural enemy! The sun!
You should never let direct sunlight hit the lenses of any of the high end VR headsets, as their lenses focus it onto the screen resulting in permanent damage to the OLED screen inside - the organic compounds used in OLEDs are light sensitive.
There are several reports that the Vive and the Rift suffer from that within seconds of being exposed to direct sunlight and whether or not Sony found a solution to that problem is unknown and unlikely.
The 2 reddish-pink streaks in this picture are an example of sun-damage.
Indirect light and light from artifical sources (apart from high powered lasers) however is harmless, because the light intensities reached with these is 2 or more orders of magnitude lower than direct sunlight.
