What is an aspheric lens in glasses?
The combination of an aspheric design with high-index lens materials creates a lensthat is noticeably slimmer, thinner and lighter than conventional glass or plastic lenses. Whether you are nearsighted or farsighted, aspheric lenses are thinner and lighter and have a slimmer profile than ordinary lenses.
What does aspheric lens mean?
An aspheric lens or asphere (often labeled ASPH on eye pieces) is a lens whose surface profiles are not portions of a sphere or cylinder. … The asphere’s more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens.
What are the advantages of aspheric lenses?
Aspheric plus lenses reduce magnification for a more natural appearance, and 2. The decreased center thickness uses less material, resulting in less weight. Traditional lenses in high-plus powers cause the wearer to look directly in the lens center for good vision.
What is the difference between spherical and aspheric contact lenses?
By contrast, aspherical contact lenses don’t have a perfectly spherical shape. … In contrast, spherical contacts have a constant curvature and power across the lenssurface. The curvature of an aspheric contact lens deflects light rays in a way that corrects spherical aberration.
