Convex lenses are those that are wider in the center than they are on
the top and bottom. They bend light towards an axis though the center
of the lens. That's the opposite of Concave lenses (bowl-shaped) that
bend light away from the lens.
What's really interesting is that you can use lenses by themselves
or together with other lenses to make some really neat things.
You can find lenses in many places. Some very common places to find
lenses are glasses, binoculars, microscopes, telescopes, magnifing
glass, and CD players.
