Spherical lens means that both the inner and outer sides of the lens are spherical, or one side is spherical, and the other half is plane. The surface shape of an aspherical lens is a lens whose radius of each point on the surface shape is different, which is determined by the multi image higher order equation.

Introduction to Spherical Lens

The aspherical design of spherical lens is a kind of design that complements the shortcomings (aberration) of the spherical design of lens, and various curvature radii are used on the convex surface of the whole lens. In theory, the lens with this design can achieve the same visual effect as the eyepiece. In addition, the curvature of the lens decreases, and the thickness of the lens decreases Low, the wearer's glasses look closer to reality. The convex or concave surface of the lens is like a part cut from the sphere, which is called spherical lens. Convex or concave lenses for myopia or hyperopia have only one radius of curvature. The convex surface of the lens with inner surface tc for astigmatism has one radius of curvature, and the concave surface has two radii of curvature that intersect vertically.
