A '''vergence-accommodation conflict''' ('''VAC'''), also known as an '''accommodation-vergence conflict''', is a phenomenon in the human visual system that occurs if the brain receives mismatching cues between [[vergence]] and [[Accommodation (eye)|accommodation of the eye]]. This commonly occurs in [[virtual reality]] devices, [[augmented reality]] devices, and binocular flat focus autostereoscopic displays. The effect can be unpleasant and cause eye strain. | A '''vergence-accommodation conflict''' ('''VAC'''), also known as an '''accommodation-vergence conflict''', is a phenomenon in the human visual system that occurs if the brain receives mismatching cues between [[vergence]] and [[Accommodation (eye)|accommodation of the eye]].
