	'''Flat Focus''' refers to an [[optical system]] design, common in [[virtual reality]] (VR) and [[augmented reality]] (AR) [[head-mounted display\|headsets]] (HMDs), where the [[lens\|lenses]] are optimized to bring light originating from the [[microdisplay]] (the screen) to a sharp [[focus]] at a single, fixed [[focal plane]]. This means that regardless of the apparent depth of virtual objects depicted on the screen, the light reaching the user's eye always appears to emanate from this specific, unchanging distance.
