Exploring the Depths--of Vision!

Now you see it... How well can you catch a ball with just one eye open? Put your depth perception to the test and see how you do!  Credit: George Retseck

Did you know that there is a type of giant clam that has thousands of small eyes covering its body? It's called Tridacna gigas, and it lives in the South Pacific Ocean. Although it has a lot of them, T. gigas's eyes are fairly primitive compared with ours. (So don’t be too jealous that you don’t have thousands of eyes, too!)

All vertebrate animals (including humans) have two eyes these days. Humans have developed an amazingly complex visual processing system that allows us to collect and process a tremendous amount of information—in the blink of an eye! Our visual system is so good at processing information for us that we usually don’t even notice what it’s doing. In this activity we’re going to explore some of the amazing abilities of that system. So get ready to say, “thanks, eyes!”
