Typical lenses are spherical in shape. On the other hand, aspheric lenses are manufactured with differing degrees of curvature over their surface. This allows them to be thinner and flatter than most other lenses, as well as have a much larger usable portion than a standard lens. Aspheric lenses are perfect for high astigmatism prescriptions.
Some of the benefits are that there is less bulging in the eyeglass lens which provides you with a sleaker side profile. The thinner lenses also open up many more frame options to those with strong prescriptions. Moreover, you’ll love how lightweight they are, how they provide better peripheral vision and their higher image quality.
