Spherical lenses for eyes degrees generally below -400 degrees, if the higher the degree, spherical mirror lenses will be thicker, the oppression of the nose becomes large. This is also a drawback of the spherical lens compared with aspherical lens.

Two: What is non-spherical mirror

Strictly speaking, any refractive surface is not spherical lenses are aspheric, aspheric lens can be a progressive spherical mirror development in the past using a spherical mirror design, the aberration and distortion increases, there will be the impact is unclear phenomenon, vision distortion, narrow field of vision and so on.
