Single-plane focus
From XVRwiki
Jump to navigationJump to searchFlat focus is a property of a display that has a single focal plane that stays still.
All commercially sold VR headsets are flat focus. But it is theoretically possible to make one that has a wide focal range.
Flat focus headsets cause a vergence accommodation conflict if a user tries to focus something up very close or very far away.
Flat focus is generally unsuitable for close work.
