The lens is one of the significant discoveries made by humans. For example, humans used a lens to make distant objects appear nearer; small objects appear larger and blurry objects appear clear i. Lenses used to accomplish these tasks fall into two categories of simple lenses as Convex and Concave Lenses. In this article, we will be closely looking into the Concave lens and its characteristics. A concave lens is a lens that diverges a straight light beam from the source to a diminished, upright, virtual image. It can form both real and virtual images. Concave lenses have at least one surface curved inside. A concave lens is also known as a diverging lens because it is shaped round inwards at the centre and bulges outwards through the edges, making the light diverge. They are used to treat myopia as they make faraway objects look smaller than they are. The demonstration in this video uses lasers and lenses to simulate what happens inside the human eye.

A real image close real image An image that is formed where the rays of light are focused. A virtual image close virtual image An image from which rays of light appear to come but do not do so in reality. The type of image formed by a convex close convex An object or shape that curves or bulges outwards, like a circle or sphere. Cameras and eyes contain convex lenses. For a distant object that is placed more than twice the focal length close focal length The distance between the centre of the lens and the focal point. Projectors contain convex lenses.
