SPHERICAL spherical image

spherical description image

The surface of this lens adopts a spherical design. Both the front and back surface are spherical in nature.

REGULAR ASPHERICAL regular aspherical image

An aspheric design is applied onto the front surface remains spherical. Compared to a spherical design, regular aspheric lenses are thinner, lighter and have better off-axis performance.

ATORAL ASPHERICAL atoral aspherical image

Optcal superior to the regular aspheric design, Atoral Aspheric lenses employ a dual-aspheric back surface design when correcting for astigmatic errors. These lenses provide wearers with high definition vision.
