A new soft lens called SV-38, with an aspherical front curve, should enhance the quality of vision since it controls better for spherical aberration. We compared the visual performance of spectacles, SV-38 and one type of conventional spherical soft lens on 28 eyes. The results of the ...

The designs of aspheric IOLs are based on the average corneal spherical aberrations reported in large-scale clinical studies to achieve ideal outcomes for subjects with ocular aspherical aberrations. However, few studies have investigated the distribution of corneal spherical aberrations in cataract patients...

Method for Manufacturing contact lenses Toric simple vision, bifocal or Progressive Multifocal Aspherical or spherical, and contact lenses so produced.A method is described for the preparation of a contact lens finished spherical single vision, bifocal or multifocal spherical or spherical, or addition ...
As a result, spherical lenses have been applied widely and become a fundamental sort of element in the optical industry [1]. Like aspherical optics, the fabrication technology of the spherical lens with sub-micrometer form accuracy and nanometer surface efficiency is always attractive, especially ...
