ZEISS Single Vision AS

The Classic Plastic Lens with an Aspheric Surface Design

Thanks to its rotationally symmetrical, aspheric front surface, ZEISS Single Vision AS displays a flatter front curvature and excellent visual quality. It is therefore visibly flatter and thinner than a ZEISS Single Vision Sph lens with the same power, especially in the plus range.

ZEISS Single Vision AS is recommended for lens wearers with high prescriptions who want cosmetically attractive, lightweight lenses with improved optics.

    Spherical aberration

    Spherical aberration

    Correcting the spherical aberration

    In spherical lenses peripheral rays are more strongly refracted than rays near the optical axis. This aberration is known as spherical aberration.

    The spectacle lens wearer will perceive this aberration as blur, especially when not looking through the optical centre of the lens.

    Aspherical Surface Design

    Aspheric surface with uniform flattening

    The solution: Aspherical Surface Design

    If the surface of the lens is "folded open" in the peripheral areas so that the surface structure deviates from the spherical shape (aspheric surface). All rays coming from the distance meet again at one point. The aberration is corrected.

    A positive side-effect of this flattening is that it leads to thinner and lighter lenses. This effect is most evident with high plus powers. In this case, the reduction of the centre thickness also leads to a reduced magnifying effect (eyes look more natural).

    ZEISS Single Vision AS 1.67

    ZEISS Single Vision AS 1.67 is an extremely thin single vision lens in the range of plastic lenses available from ZEISS. It is extremely light and a very special lens in many ways.
    In 1997 ZEISS was Europe’s first manufacturer to succeed in polymerising a plastic lens with the super-high index 1.665 for batch production. Only by polymerising the material ourselves is it possible to provide lenses made of the high index plastic material with the proven surface know-how of ZEISS – whether it is the special asphere for single vision lenses or the progressive design of ZEISS progressive Individual 2.

    Recommended power range: Medium to high myopia from sph -3.00 D to sph -10.00 D. Low to medium hyperopia from sph +2.00 D to sph +6.00 D

    ZEISS Single Vision AS 1.6

    ZEISS Single Vision AS 1.6 is a high index plastic lens with an aspheric surface design. This combination results in flat, thin and light lenses which provide excellent visual quality. ZEISS Single Vision AS 1.6 is recommended for patients with high prescriptions who want cosmetically attractive, lightweight lenses.

    Recommended power range: low to medium myopia from sph -2.00 D to sph -6.00 D. Low to high hyperopia from sph +1.00 D to sph +7.00 D

    ZEISS Single Vision AS 1.5

    With the introduction of ZEISS Single Vision AS 1.5, ZEISS placed its range of plastic single vision lenses on an even broader basis: ZEISS Single Vision AS 1.5 is a lightweight lens made of the time-tested material CR 39 which offers even more benefits than ZEISS Single Vision Sph 1.5.

    Recommended power range: low myopia from sph -1.00 D to sph -3.00 D. Low to medium hyperopia from sph +1.00 D to sph +5.00 D
