Self-reported Magic Eye stereogram skill predicts stereoacuity.
Autostereograms--commonly known as Magic Eye stereograms (MESs)--are two-dimensional images that support stereoscopic depth perception given an appropriate crossing or uncrossing of the eyes. We find that self-reported MES skill is highly predictive of stereoacuity as measured by a standard clinical test (r142 = 0.45, p < 0.0001; TNO test). Indeed, in our sample of 194 individuals, those who report poor MES skill have a five-fold increased risk of stereo impairment. Those who report poor MES skill also require on average five times greater binocular disparity to perceive stereoscopic depth than those who report good MES skill. Reported MES skill thus carries significant information about stereoacuity.
