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.
To distinguish between a convex and concave lens using a printed piece of paper, hold the lens against the paper with the curved side facing up. If the text appears larger and clearer through the lens, it is a convex lens. If the text appears smaller and upside down through the lens, it is a concave lens.
The difference is that when virtual image is formed by the concave mirror...it is larger than its original size..but when it is formed by the convex mirror..it is smaller than the original size....
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
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.
A magnifying lens is typically convex in shape.
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 ---> ()
Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.

)( is a concave lens() is a convex lens
Double-convex lens
they are both lenses and form images
projector have concave or convex
A convex lens magnifies.

A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
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 .
