"Concave" vs. "Convex": What's The Difference?
Concave lenses—those that are thicker around the edges than they are in the center— disperse light rays, which can have the effect of making things look smaller or farther away. Convex lenses—those that dome outward and are thicker in the center than they are around the edges—make light rays converge. Convex lenses have the opposite ...
