Rembrandt's Lazy Eye

Based on self-portraits, doctors think Rembrandt had a lazy eye; indeed, it may have helped him as he could more easily portray the 2-D world he saw onto a 2-D canvas.

Having a lazy eye is called extropia, when one of the eyes points outward away from the position normal for stereoscopic (3-D) vision. Extropia is just one of a family of conditions grouped under the disorder strabismus. Other manifestations of strabismus are esotropia (one eye pointing inwards) and hypertropia (one eye turning upwards).
