[visionlist] Focal distance / accommodation distance HTC Vive Pro

[Oberfeld-Twistel, Daniel]

Dear list,

we'd like to determine the focal distance in the HTC Vive Pro headset, in order to use exactly this distance for tests of visual acuity before the actual VR experiment. An internet search produced a variation of estimates, ranging from 0.75 m to 2 m or even infinity. So we are wondering if someone here made optical measurements of the Fresnel lenses inside the Vive, to determine the effective focal distance of the display.

Best

Daniel
