Monovision lenses have long been known to cause a slight decline in depth perception because, as the name suggests, they compromise the person’s ability to see in stereo. That’s because a given object appears sharp in one eye and blurry in the other, so the brain suppresses the blurry image to some degree.

Why is driving dangerous for someone with poor depth perception?
