How are aspheric contact lenses work? In contrast, spherical contacts have a constant curvature and power across the lens surface. The curvature of an aspheric contact lens deflects light rays in a way that corrects spherical aberration. This reduces blur, improves depth perception, enhances contrast sensitivity, and provides clearer vision.What does aspherical lens mean? An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.What is spherical contact lens? A spherical contact lens scatters the light that enters the eye through the contact lens, creating multiple focal points. The gradient curvature design of an aspheric contact lens is meant to decrease the scatter that occurs when light enters the eye.What is contact lens? Contact lens. A contact lens, or simply contact, is a thin lens placed directly on the surface of the eye. Contact lenses are ocular prosthetic devices used by over 150 million people worldwide, and they can be worn to correct vision, for cosmetic, or therapeutic reasons.

An aspheric contact lens designed to correct for this induced SA should have zero SA irrespective of lens power (red line [#2] in Figure 3a). Also, because the average human eye has roughly +0.10D of spherical aberration (Thibos, Hong et al, 2002), an aspheric contact lens with 0.10D of SA would correct this.
