Rather than use focusing and stereoscopic vision like humans or head-wobbling motion parallax like birds, the spiders have two green-detecting layers in their eyes — one in focus and one not. By comparing the two, the spiders can determine the distance from objects. Scientists discovered that bathing spiders in pure red light “breaks” their distance measuring ability.
