Depth perception is the ability to judge distances and see the world in three dimensions. It allows you to understand how near or far objects are from you. This skill depends on both eyes working together to combine two slightly different images into one clear view. Good depth perception is essential for everyday activities such as driving, sports, climbing stairs, and moving safely through your environment.
