There are many types of light—some visible and some invisible to the human eye. For example, our eyes and brain don't have the tools to process ultraviolet light when it hits our eyes, making it invisible. But there is another type of light that is invisible simply because it never reaches our eyes. When light hits certain surfaces, part of it sticks and remains behind rather than being transmitted or scattered away. This type of light is called near-field light.
