How do lenses work?

In a convex lens (sometimes called a positive lens) the glass (or plastic) surfaces bulge outwards in the center giving the classic lentil-like shape A convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point
