A cloudy day with no obvious sunshine: PhotoFusion still protects the eyes against harmful solar UV rays.
When outside, PhotoFusion lenses darken according to the sunlight giving 100% solar UV protection.
Also known as photochromic lenses, self-tinting lenses have been around since the 1960's. The small, yet significant discovery made by chemist Stanley Donald Stookey and his colleague, William Armistead, made it possible to have spectacle lenses that react to UV rays remarkably well. Ever since then, a lot has happened in view of the quality and performance of self-tinting lenses and they are extremely popular amongst many people who are dependent on their glasses and constantly going indoors and outdoors.
What are the differences in quality amongst self-tinting lenses?
With self-tinting lenses, the annoying need to change glasses is a thing of the past. Latest market research by ZEISS show that spectacle wearers however have very clear criteria regarding the quality and performance of self-tinting lenses:
- To be comfortable to use, self-tinting lenses must adjust very quickly to the changing light conditions.
- To attain optimal vision, self-tinting lenses must become really dark in sunlight and completely clear indoors.
- Self-tinting lenses must be effective and also offer 100% UV protection.
- To look good, self-tinting lenses should be available in attractive, harmonious tints.
- Self-tinting lenses should have a long life performance and high performance.
- 95 % evaluate the performance of PhotoFusion as equal or better than other self-tinting lenses.
- 88 % are very satisfied / satisfied with PhotoFusion lenses.

GT2 3D ASIANA
Carl Zeiss Vision's commitment to cutting-edge research has shaped a new level of interaction between the lens and the eyes. The result is an improvement in the level of comfort, reduction in visual fatigue and an increase in the wearer's field of vision.In our constant pursuit to give wearers clarity of vision, we have developed the newest progressive lens from Carl Zeiss, GT2 ASIANA.
With more than 160 years experience in research and development across all facets of optics, Carl Zeiss is leading the way in product innovation. This has led our lens design research scientists to develop an enhanced progressive for the Asian face, resulting in the development of GT2 3D Asiana by ZEISS.
The shape of a face is an important factor when it comes to designing progressive lenses. The craniometry, or the underlying bone structure of the head and face, has a marked difference between Caucasian and Asian populations. Often, the cheek structure of the Asian face has a flatter profile and the bridge of the nose is less pronounced. These two factors combined reduce the amount of Pantoscopic Tilt and the degree of Bow Angle found in Asian wearers.
Carl Zeiss Vision's research team evaluated the Position-of-Wear of spectacle lenses in frames worn by a group of Asian patients. This research involved the measurement of the key Position-of-Wear values on a range of subjects using the highly accurate ZEISS-designed digital centration instrument known as the RVT (Relaxed Vision Terminal). As a result of this study, the Position-of-Wear values for the new GT2 3D Asiana design were found to be essentially different to that of a Caucasian wearer.
GT2 3D: Closing the gap between vision and reality.
Traditionally, progressive lenses are manufactured, fitted and adjusted to the customer’s need separately and are optimised under monocular conditions. But humans have two eyes – and it is only perfect interaction of both eyes that can ensure a perfect 3D image is formed by our brain.
Carl Zeiss Vision has accepted the challenge to synchronise binocular vision so that it creates improved 3D vision. GT2 3D – a new generation of ZEISS progressive lenses – ensures a natural 3D experience and a new dimension of spatial perception.
GT2 3D – developed for natural spatial perception.
GT2 3D is a new generation of premium progressive lenses which provide a much more natural 3D experience than traditional progressive lenses – and makes wearing your progressive spectacles less of a strain and a more comfortable experience.
GT2 3D progressive lenses optimise the complex interaction between your both eyes and their visual surroundings.
An optimisation method unique to ZEISS, allows the ideal allocation of the binocular viewing zones. This is achieved by defining the lens surface at more than 40,000 different points, ensuring that the eye path follows the centre of these 3D zones. This technology combined with the measurement of the individual distance of your eyes ensures an ideal synchronisation of the eyes – and closes the gap between vision and reality.
The scientists at Carl Zeiss Vision have been extensively studying the complex interaction between the eyes and progressive lenses for decades – and have succeeded in developing a progressive lens design with excellent binocular synchronisation.
Benefits for You with ZEISS GT2 3D:
Natural spatial perception:
- Sharp 3D vision at all distances.
Large viewing zones:
- Up to 40 % larger binocular zones.
- Large and clear distance zone.
- Well-balanced intermediate zone.
- Large and clear near zone.
High spontaneous acceptance:

ZEISS Individual FrameFit: From evolution to revolution
With ZEISS Individual FrameFit, Carl Zeiss has developed a progressive lens with revolutionary properties: on the basis of the Rx and fitting data provided by the optician, we compute and produce a progressive lens tailored precisely to each individual requirements.
Unlike earlier generation progressives, the PD, back vertex distance, pantoscopic angle, boxed frame dimensions and near object distance are all incorporated in the design of the progressive lens for each individual case.
Thanks to pioneering, innovative production technology, what was considered impossible in the past has now become reality.
Development of ZEISS Individual FrameFit
Unlike traditional progressive lenses, the patient's specific centration data are also incorporated in the design of progressive lenses. Manufacturing technology has made it possible to produce progressive lenses which are tailored to every patient's own individual requirements, further enhancing the visual comfort for spectacle wearers.
What makes ZEISS Individual FrameFit so revolutionary?
In addition to the incorporation of various parameters in the progressive lens design for the very first time, we compute and produce Gradal Individual FrameFit individually for every lens power.
In traditional PAL design, lens optimisation is performed for a power within a certain range, i.e. not for an individual dioptric power, but for a group of powers. Carl Zeiss has made this tailor-made process as accurate as possible by increasing the number of groups (base curves) used.
The design of Gradal Individual FrameFit allows the lens to be customised for every power (dioptre, cylinder, axis, addition, prism, base). This is combined with the revolutionary possibility of incorporating various parameters in the lens design.
Maximizing individuality. Minimizing aberrations.
The outstanding feature of Gradal Individual FrameFit is its very large usable fields of vision – even for data which deviate from the norm.
In the past, it was technically impossible to incorporate the pantoscopic angle, back vertex distance and PD in the computation and production of a progressive lens. Standard values had to be substituted for these parameters. This meant that the pantoscopic angle and BVD (back vertex distance) recommended by the lens manufacturer had to be observed to obtain optimum results in the fitting process. However, this was not always possible – often for anatomical reasons.
Until now, no allowance was made for the wearer’s PD despite the fact that, along with the distance correction and the addition, it influences the convergence of the eyes required for near vision. In other words, the variable inset of the intermediate and near zones is partly determined by the PD of the wearer.
The outstanding feature of Gradal Individual FrameFit is its very large usable fields of vision – even for data which deviate from the norm.
Benefits for You with ZEISS Individual FrameFit:
- Physiologically adapted design for maximum tolerance – even for unusual prescriptions
- Wide progression zone
- Individual progression length
- Smooth transitions for optimum visual comfort
- Wide, stable near zone
- Horizontal symmetry for optimum binocular vision
- Outstanding vision and an attractive appearance: asphere and atorus for flat curvature and excellent visual quality
- Variable inset for large field of view in near vision: takes into account individual wearer’s reading distance and PD – therefore convergence-aligned position of the progression and near zones.
