Our vision. It’s one of the most complex functions of the human body. Think for a moment of all the different ways in which your vision helps you function in the world around you, and enriches your life. It gives you the big picture of what’s happening around you, allowing you to scan a room, or the landscape. It allows you to work up close, to write a letter or hammer a nail. It helps us to pick out a particular object we’re looking for, whether a brand of soup at the grocery store, or a bird in a tree outside a window.
