Answer 2

Answer:

This type of lens is thicker at the center and thinner at the edges. If those surfaces are bent outwards, the lens is called a biconvex lens or simply convex lens. ... These types of lenses can converge a beam of light coming from outside and focus it to a point on the other side.

A lens bound by two spherical surfaces bulging outwards is called a bi-convex lens or simply a convex lens. A single piece of glass that curves outward and converges the light incident on it is also called a convex lens. They are both thicker in middle than near the edges.
