This is the old and conventional shape of lens. There are inherent disadvantages in this form of lens. These type of lens tend to bulge out of the frame and also magnify or reduce the appearance of the eyes depending on the correction.

Gradient index micro lenses have a radially varying index of refraction that causes an optical ray to follow a sinusoidal propagation path through the lens. They combine refraction at the end surfaces along with continuous refraction within the lens.

A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens consists of a single optical element. Lenses are typically made of glass or transparent plastic. A lens is biconvex (or double convex, or just convex) if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. A lens with two concave surfaces is biconcave (or just concave). If one of the surfaces is flat, the lens is plano-convex or plano-concave depending on the curvature of the other surface. A lens with one convex and one concave side is convex-concave or meniscus. It is this type of lens that is most commonly used in corrective lenses.
