A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out 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 (myopia).
after light rays have passed through the lens, they appear to come from a point called the principal focus. This is the point onto which the collimated light that moves parallel to the axis of the lens is focused. The image formed by a concave lens is virtual, meaning that it will appear to be farther away than it actually is, and therefore smaller than the object itself. Curved mirrors often have this effect, which is why many (especially on cars) come with a warning: Objects in mirror are closer than they appear. The image will also be upright, meaning not inverted, as some curved reflective surfaces and lenses have been known to do.
A convex lens is also known as a converging lens. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis. They can be identified by their shape which is relatively thick across the middle and thin at the upper and lower edges. The edges are curved outward rather than inward. As light approaches the lens, the rays are parallel. As each ray reaches the glass surface, it refracts according to the effective angle of incidence at that point of the lens. Since the surface is curved, different rays of light will refract to different degrees; the outermost rays will refract the most. This runs contrary to what occurs when a divergent lens (otherwise known as concave, biconcave or plano-concave) is employed. In this case, light is refracted away from the axis and outward.

✔✔✔CONCAVE LENS ALSO CALLED CONVERGING MIRROR. THE LIGTH RAYS AFTER REFRACTION FROM IT APPEARS TO CONVERGE TOWARD FOCUS. THE IMAGE FORMED CAN BE REAL,VIRTUAL, INVERTED,ERECT AND CAN BE DIMINISHED OR OF SAME SIZE OR MAGNIFIED.
✔✔✔CONVEX LENS ALSO CALLED DIVERGING MIRROR BECAUSE THE LIGTH RAY AFTER REFRACTION DIVERGES.THE IMAGE FORMED IS ALWAYS VIRTUAL, ERECT AND DIMINISHED.
✨✨✨HOPE IT HELPS ✨✨✨
