摘要

Stereopsis, the perception of depth based on the binocular disparity of the images projected to the retinas of the two eyes, adds richness to our perception of our 3D world. However, 3-5% of the population is stereo-blind and is unable to use binocular disparity to perceive depth or has a condition called "stereoanomaly" that results in seriously impaired stereovision. Stereoblindness and stereo-anomaly often result from a "turned eye" or "lazy eye" during early childhood. If not treated early enough, these conditions could lead to reduced or no stereopsis. Although treatment is seldom undertaken in adults, we show here that perceptual learning—the repetitive practice of a demanding visual task—can induce the recovery of stereopsis in adults with abnormal binocular vision.
