−A '''focal conflict''' is when a brain receives mismatching cues between eyes' accommodative [[focus]] and [[vergence]]. It results in the human brain not being sure of the distance of something. It makes it so the human brain cannot arrive at a solid determination of how far away something is. It is disorienting.

The effect can be unpleasant and cause eye strain. This can happen with fixed-focus twosight displays, such as VR headsets and AR headsets, for example the [[Meta Quest]], [[Oculus Rift]], and [[Microsoft HoloLens]]. Focal conflict can occur in binocular flat focus autostereoscopic displays.
