Jumping Spiders’ Eyes May Inspire New Camera Technologies

In a paper published in Science this week, Japanese researchers reported on a discovery that jumping spiders use a method for gauging distance called "image defocus", which no other living organism is known to use. 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.

Amazing Macro Photos of Animal Eyes

After seeing his close-up photographs of human eyes become enormously popular last year, photographer Suren Manvelyan turned to a more difficult subject: animals. He somehow managed to create a series of photographs showing the stunning eyes of animals ranging from crocodiles to horses.

Turning the Eye into a Camera Sensor

What if in the future, the human eye itself could be turned into a camera by simply reading and recording the data that it sends to the brain? As crazy as it sounds, researchers have already accomplished this at a very basic level.
