Portable self-adhering optical lens

An apparatus for magnifying a reflection in a mirror, the apparatus comprising:

• an optical lens comprising:
• a conical concave surface located on a first side of the optical lens, and
• a conical convex surface located on a second side of the optical lens opposite the first side,
• an optical axis of the optical lens being formed along a central portion of the conical concave surface and a central portion of the conical convex surface,
• the conical concave surface having a first radius of curvature and the conical convex surface having a second radius of curvature greater in magnitude than the first radius of curvature;
• and
• an adhesive material affixed to at least a portion of the conical concave surface causing at least the portion of the conical concave surface to be self-adherable to a mirror, wherein, when at least the portion of the conical concave surface is self-adhered to the mirror, the optical lens is configured to magnify mirror images viewed through the optical lens and the mirror.
