What is ZEISS ClearView? ZEISS introduces a new premium freeform lens design for finished single vision lenses designed to achieve clear vision from the lens centre to the periphery, in a thin and flat lens without compromising optics.

Why freeform customization for single vision stock lenses? ZEISS has recognized the existing challenges in single vision lenses as an opportunity and developed a new product that overcomes these limitations. The result is ZEISS ClearView lenses. As an innovation leader, ZEISS has found a way to transfer complex freeform technology to the production of single vision lenses. To do this, ZEISS has developed a new, optimized design for this type of lens that is realized with the help of ZEISS' cutting-edge ClearForm technology. The result is a single vision lens that is very thin and flat and offers very good clarity across the entire lens.


Finished single vision or stock lenses are the most sold ophthalmic lens type worldwide. Now ZEISS has identified a way to get many attributes of complex single vision freeform lens designs into these “stock” lenses. The result is ZEISS ClearView Finished Single Vision lenses. It offers high optical quality in order to provide clear vision from the lens center to the periphery and is very thin and flat at the same time.

As mentioned above, whether it’s used for reading or distance vision, finished single vision (FSV) lenses are the most purchased type of eyeglass lenses. Statistics confirm that worldwide, 75 percent and in Asia, as many as 83 percent of spectacle lens wearers who obtain eyeglasses for vision correction purchase single vision lenses.1  The vast majority of these single vision lenses are sold as stock lenses, as they offer the advantages of low cost and fast delivery times for both the retailer and the spectacle wearer. However, FSV lenses often cannot reach the full precision potential a freeform-optimized lens can offer. With ZEISS ClearView FSV, it’s precisely this challenge that is addressed. The new lenses offer many of the advantages of freeform-optimized single vision lenses, but with the cost and speed benefits of a stock lens.


To get a better understanding of this ZEISS innovation, it makes sense to take a closer look at single vision lens designs. The choice of lens design impacts the aesthetics, comfort of the lens, and optical performance. Spherical (SPH) single vision lenses, for example, are typically optimized using only one free parameter (the radii of curvature of the lens surface). Aspheric (AS) single vision lenses have a more complex shape. Typically, the lens front surface is optimized with a low number of free parameters in one meridian. Double aspherical single vision lenses are generally optimized using twice the number of free parameters. But in summary, all these lens designs do not adequately address the peripheral optics of most prescriptions.

Freeform lens design – stepping beyond spherical, aspherical, or double aspherical

In the 1990s ZEISS pioneered freeform lens design technology in surfaced lenses – which are made to order. And now it is also ZEISS who has introduced single vision freeform lens design to improve the optics and aesthetics of the FSV lens category. This is possible due to a specially created freeform lens design for FSV and the new ClearForm manufacturing process that incorporates this design into the finished lens. The lens design includes point-by-point optimization with the use of around 700 free parameters across the lens. This ClearForm process utilizes the latest computer numerically controlled (CNC) generators that use special diamond cutting and polishing tools to surface the complex shaped molds for ZEISS ClearView FSV lenses. The final lens delivers, on average, a three times larger zone of excellent clear vision, to provide the wearer with more clarity from the lens center to the periphery.2 It is therefore designed to deliver a higher level of comfort and satisfaction for the spectacle wearer. In addition, the complex lens shapes allow wearers to experience this vision clarity in a flatter and thinner lens than conventional FSV lens designs that rely on steeper base curves to provide just acceptable optical performance. In numbers, this means: ZEISS FSV ClearView lenses are on average 34 percent flatter across all prescriptions and up to 16 percent thinner compared to typical spherical single vision lenses
