context_page_description: In 2-dimensional geometry, a lens is a convex region bounded by two circular arcs joined to each other at their endpoints. In order for this shape to be convex, both arcs must bow outwards. This shape can be formed as the intersection of two circular disks. It can also be formed as the union of two circular segments, joined along a common chord.
