Explanation:

concave lens -

diverges the light rays

thinner in the middle and thicker at the edges

The image formed is an upright, virtual, and smaller size than the object.

example - glasses, some telescopes, spy holes in the doors, etc.

convex lens -

focuses the light rays to a specific point

thicker in the middle and thinner at the edges

The image formed is inverted, real, and smaller than the object when the object is placed at focus. The image formed is the inverted, real, and the same size as the object
