Get in touch

Freeform technology in standard single vision
Available as surfaced and finished SV
Very thin and very flat without optical compromise
On average 3x larger areas of excellent vision clarity

Freeform in standard Single Vision

Point-by-point design optimization for a highly complex surface. This results in an SV 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 SV Lenses come standard with ZEISS UVProtect Technology embedded in the lens material.

Standard SV lenses compromise on optics.

Standard single vision (SV), whether spherical (SPH) or aspherical (AS) are globally the most sold lens type. This lens category is delivered either by stock finished single vision (FSV) with their distinct advantages of a lower cost and fast delivery time, or by SV surfaced. Standard single vision lenses have fallen behind in one of the most important features for every eyeglass wearer: they typically do not provide great optics away from the lens center. In particular, the demand for flatter and thinner SV lenses has compromised their peripheral optical performance.

More information

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 Aspherical (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 Aspherical (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 SV Lenses

Inspired by patients demand

Patients demand comfort and clarity, but Single Vision lenses compromise on optics.² ZEISS has tackled the opportunity for optical improvement of conventional SV lens designs by identifying a method to evaluate optical quality and improve lens optimization.

A breakthrough in optics and aesthetics.

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

ClearView SV Lenses

A new standard in single vision at ZEISS.

ClearView SV Surfaced	ClearView Finished SV
Freeform/Digital Lens Surfacing Technology Previously only utilized for the most premium lens designs	ClearForm® Technology New 7 step process that bring Freeform designs to stock lenses
Made to order	Held on stock for fastest delivery

The ZEISS ClearView Freeform SV lens design is brought to standard single vision via 2 delivery / production methods:

ClearView SV surfaced lenses are produced using the latest Freeform Rx surfacing equipment, previously used only for the most premium lens categories - now fully utilized and embraced for standard single vision category
ClearView Finished SV stock lenses are produced using a new innovation from ZEISS called ClearForm^® technology – this is the process which brings a Freeform lens design into a pre-made finished stock lens.

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.
