it makes image smaller than the object
A concave lens causes rays of light to diverge, meaning they spread apart as they pass through the lens. This results in a virtual image that is seen as if it is coming from a point behind the lens. The image formed by a concave lens is always upright and smaller in size compared to the object.
A double convex lens is thicker in the middle and thinner at the edges, causing light rays passing through it to converge. A double concave lens is thinner in the middle and thicker at the edges, causing light rays passing through it to diverge.
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
Cancave lens always gives virtual, erect and diminished image.

Virtual image
concave lens will form exact mirror image.
Cancave lens always gives virtual, erect and diminished image.
image formed by the concave lens will be erect , virtual and smaller than the size of object.
Double-convex lens
No, a concave lens alone cannot form a real image on a screen. Concave lenses always produce virtual, upright, and diminished images.
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
A concave lens forms a virtual image of an object located at a distance greater than the focal length of the lens. The image is always upright and reduced in size compared to the object.
