ZEISS ClearView Single Vision Lenses

Single Vision just got upgraded.

With ZEISS ClearView Single Vision Lenses you can offer your patients all the benefits of freeform optimization in standard single vision lenses; and is available as either an Rx surfaced or a Finished Single Vision stock lens.

  • On average 3× larger area of excellent vision clarity [1]
  • Very thin and very flat without optical compromise
  • Freeform technology in standard single vision lenses
  • Freeform in Standard Single Vision Lenses

    Point-by-point design optimization for a highly complex surface. This results in a Single Vision lens that is both very flat and thin and achieves excellent optics – with clear viewing from the lens center to the periphery.

  • ZEISS UVProtect Technology

    ZEISS ClearView Single Vision Lenses come standard with ZEISS UVProtect Technology embedded in the lens material.

Standard Single Vision lenses compromise on optics.

Across the globe, standard single vision lenses are the most sold ophthalmic lens type thanks to their low cost and fast delivery time. However, standard single vision lenses typically do not provide great optics away from the lens center. The demand for flatter and thinner standard single vision lenses, has also compromised their peripheral optical performance.

Single Vision Lenses

Standard

Spherical (SPH) Lenses

  • Optimized by using only one free parameter in the lens radius
  • Peripheral rays are more strongly refracted than rays at the lens center (spherical aberrations) resulting in optical compromise
  • Any acceptably flat lens results in peripheral blur for the wearer

Good

Aspheric (AS) Lenses

  • Optimized by using five free parameters in one meridian
  • One aspherical surface, usually on the front, but the back surface remains a simple toric surface (two spheres at 90°)
  • Provides optics similar to SPH, while improving on flatness
  • When sph and cyl power increase, the same constraints result in increasing optical errors

Better

Double Aspheric (DAS) Lenses

  • Optimized using nine free parameters in two perpendicular meridians and blended in between
  • Replaces the toric back surface of an AS with two aspherical shapes perpendicular to each other (atoric)
  • Improvement on an AS design, but blended area still compromises the optics

Best

Freeform Single Vision Lenses

  • Point-by-point lens design optimization for a highly complex lens surface
  • The result is an FSV lens that is both very flat and thin and achieves excellent optics – with clear viewing from the lens center to the periphery

ZEISS ClearView Single Vision Lenses

Inspired by patient demand

Patients demand comfort and clarity, but standard single vision lenses compromise on optics.2  ZEISS tackled the biggest opportunity for optical improvement in conventional single vision lens designs. We did this by advancing single vision lens optimization and by identifying a method to evaluate optical quality. Assessing the quality of optics in single vision lenses is complex. Lens power is typically measured in the center, but little attention is paid to optical performance and vision clarity across the entire lens.

A breakthrough in optics and aesthetics.

With ZEISS ClearView Single Vision Lenses, patients will experience excellent vision clarity from the lens center to the periphery, in a lens that is flatter, thinner, and more attractive than standard lens designs that rely on steeper base curves to provide acceptable optical performance.

A breakthrough in optics and aesthetics.

  • 78 %

    After one week of wear, 78% of study participants preferred the vision performance of ZEISS ClearView SV compared to ZEISS AS.2

  • 89 %

    of wearers strongly agreed or agreed that they had experienced all day visual comfort with ZEISS ClearView.2

  • 79 %

    of wearers strongly agreed or agreed that ZEISS ClearView provides clear vision across the entire lens for near, intermediate and distance vision.2

ClearForm® Technology freeform design for finished stock lenses

Technology explained.

  • ZEISS ClearView Lens Design

    Complex mathematical simulation tools are used to calculate the required mold designs.

  • Freeform Mold Generation

    The complete freeform shapes are incorporated into the molds by using highly accurate numerically controlled (CNC) generators.

  • CMM Metrology Measurement

    Using ZEISS' industrial metrology expertise, final molds are checked for accuracy and precision with a ZEISS coordinate measuring machine (CMM) where over 1,500 points on the surface of each mold are analyzed.

  • Specialized Mold Pairing

    Special optimization of front and back mold pairings to deliver the complex free-form optics across the entire prescription range. 2D Data Matrix Code (DMC) is used in the manufacturing process to precisely track molds and lenses as part of an automated industry 4.0 process.

  • Casting/Coating/Quality Checks

    Finally, finished lenses are checked by means of CMM against the ZEISS Vision Clarity Simulation to ensure the final delivers on the optical promise.
