What are the applications of concave and convex lens in daily life?

Camera manufacturers use concave lenses in combination with convex lenses to improve the quality of photographs. Convex lenses alone produce distortion in photos, which is called chromatic distortion. Concave lenses are used in flashlights to magnify the light produced by the light source.

What are examples of concave lenses?
