Lens that possesses at least one surface that curves inwards. It is a diverging lens, spreading out those light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness. Hope this helps you :)
A concave lens spreads light apart due to its diverging nature. When light rays pass through a concave lens, they refract in such a way that they diverge away from each other. This results in the spreading out of light rays when they pass through the concave lens.
A concave lens is otherwise known as a diverging lens.
along its axis in the center
A concave lens always produces smaller images for both real and virtual objects. This is due to the diverging nature of the concave lens, causing light rays to spread out and create an image that is smaller in size compared to the object.
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.

His glasses have a concave lens.
A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.

A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
