• A lens is a transmissive optical device that focuses or disperses light beams by means of refraction.
• A simple lens consists of a single piece of transparent material, while compound lenses consist of several simple lenses arranged along with a common axis.
• A lens can focus light to form an image, unlike a prism, which refracts light without focusing.
