How are convex and concave lenses different?

Answer:
Convex bulges outward (thicker in the center than the edge)

Concave bulges inward (thinner in the center than the edge)
Convex lenses magnify when you look through then, concave lenses make things look smaller.
You can focus a distant object to a point with a convex lens (the image will be upside down).
