Abstract
A contact lens is shown with patterns of thermochromic coating over the lens. The thermochromic coating is designed to change from colored to clear at just below body temperature in a human ocular surface or about 90 degrees Fahrenheit. As the lens cools in the ambient environment outside the eye, the thermochromic coating changes from clear to colored. The pattern is designed to provide contrasting colors when the contact lens is removed from the eye.
