Aspheric Lenses

An aspheric lens usually carries a rationally symmetrical profile on an axis point creating a thinner lens and reducing spherical aberration. Aspheric lenses are ideal for heavy spherical and cylindrical prescriptions. High index lenses are often incorporated with aspheric designs creating a thin lightweight lens, considering aggressive prescriptions. Besides enhancing widened visual acuity in most cases, aspheric lenses may also create a better aesthetic appearance for patients with severe prescriptions by reducing magnification around the edges producing a more natural look as opposed to "Coke Bottle" eyes or "Tiny Eyes" effect. It is important to note that aspheric lenses should help aesthetically, but may not eliminate extreme magnification of the eyes.

Below you will find pros and cons for aspheric lenses and also leading manufatures of aspheric lenses.

Pros:

Enhanced wider visual acuity
Thinner lens design
