Answer to Thursdays trivia is...Depth perception! It is the lateral displacement of the eyes which provides two slightly different views of the same object, which the brain is able to analyse and thus calculate the rough distance of that object from us. It is, however, possible to perceive depth even with only one eye, with the help of factors like relative sizes, light and shade, etc., but not to the extent that is perceptible with binocular (i.e., two-eyed) vision.
