A concave lens helps you see far if you're nearsighted and convex lenses help you see near if you're farsighted.
Convex lens converges the light and a concave lens diverges the light..
The convex lens bulges out at the center, while the concave lens bulges in at the center. The convex lens magnifies, while the concave lens reduces.

the image formed by convex lens will converge at a point, while with a concave lens it will appear to diverge from a point.

Double-convex lens
A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()
they are both lenses and form images
projector have concave or convex
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
