A concave lens diverges light rays, causing them to spread out. This results in the formation of a virtual image that appears smaller and upright compared to the object. Concave lenses are commonly used in correcting nearsightedness.
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
When light passes through a concave lens, it diverges outward. This causes the light rays to spread apart rather than converging at a single focal point as with a convex lens. As a result, the image formed by a concave lens is virtual, upright, and reduced in size.
A concave lens is otherwise known as a diverging lens.
An air bubble in water will act like a concave lens. This is because the diverging effect on light rays passing through the air-water interface creates a virtual focus point on the opposite side of the bubble, similar to a concave 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 is also known as a converging lens, while a concave lens is also known as a diverging lens.
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 .
