HEY MATE HERE'S YOUR ANSWER ;
Curving inward, concave lenses cause light to spread out, resulting in a smaller image for the viewer. Despite being less useful than convex lenses, concave lenses have several uses, including in eyeglasses and contacts, flashlights, peepholes, binoculars, telescopes, and in photography.
Convex Lens Examples. The simplest example is the magnifying glass. The letters which are too small to read can easily be read by using a convex lens as a magnifying glass. The lens is held in such a way that the letters are within the focal length of the lens.
