Thread the Needle: Using Two Eyes Gives You Depth Perception

Closing one eye eliminates one of the clues that your brain uses to judge depth. Trying to perform a simple task with one eye closed demonstrates how much you rely on your depth perception. In this activity, learners compare their ability to perform simple tasks with one eye versus with two eyes.
