Lenses are used in cameras, telescopes, binoculars, microscopes and corrective glasses. A lens can be convex or concave .

In a ray diagram, a convex lens is drawn as a vertical line with outward facing arrows to indicate the shape of the lens. The distance from the lens to the principal focus is called the focal length .

Concave lenses are less common than convex lenses in optical engineering, but they still have some useful applications. Some examples of devices that use concave lenses are eyeglasses, peepholes ...
