A diverging lens is a type of lens that spreads out light rays as they pass through it. This happens because at least one surface of the lens curves inward, creating a thinner shape towards its centre compared to its edges. The unique characteristics of a concave lens make it effective for correcting nearsightedness or myopia in individuals with this condition. Its inner curvature causes light to disperse, producing an image that is smaller than usual for viewers. Although concave lenses may not be as widely used as convex ones, they still find applications in various products like eyeglasses and contact lenses, flashlights, viewing scopes such as binoculars and telescopes, and in photography equipment.
