Proclear Multifocal

Proclear multifocal: Just because you need bifocals doesn't mean you need to wear them.

 

Need multifocal vision correction (but want it to remain your little secret)?

Between the ages of 40 - 45, our eyes lose the ability to focus on objects up close.  It’s called “presbyopia” and a part of the natural aging process. But that doesn’t mean you have to settle for wearing your grandmother’s bifocal eyeglasses.

Enjoy the comfort and freedom Proclear® multifocal contacts offer.  

With these soft, flexible contact lenses, you’ll have clear vision at all distances—whether you're texting on your phone, working on your computer, or looking for the right street sign that’s around here…somewhere. And, you won’t need any eyeglass readers when it’s time to order at your favorite romantic restaurant.

IPSEO

Varilux Ipseo New Edition

essilor-ipseo1

With some people, head movements predominate, whereas others rely more on eye movements. This is why Varilux Ipseo lenses are individually designed to take into account the effects of the wearer’s head and eye movements.

We have gone one step further in the quest for greater visual performance...  thanks to Varilux Ipseo New Edition which offers an even higher level of personalisation through...

essilor-ipseo2

DDV, Dual Digital Vision: a front and back surface progressive approach

Dual Digital Vision is a new way of using both sides of the lens to tailor Varilux Ipseo new Edition to the physiology of each wearer.

Prismatic effects are controlled by splitting the addition between the front and the back surfaces of the lens, in order to best suit the wearer’s head and eye movements.

Patient benefits

  • The image stabiliser for head movers.

A greater proportion of the addition value is located on the concave side of the lens in order to minimise the amount of swim / sway perceived by the wearer. Having more addition of the rear surface acts as an “image stabiliser” for head movers.

  • The image stabiliser for eye movers.

A greater proportion of the add is located on the convex side of the lens. This results in a greater image magnification over a wider area of clear vision, ideal for scanning a page. Having more of the addition on the front surface of the lens acts as an ”image magnifier” for eye movers.

The ultimate personalisation

When ordering:

  • Head / eye ration, stability coefficient data must be specified.
  • Progression length will be automatically calculated unless specified (between 14mm and 18mm, by 1mm step).
  • Frame measurements (vertex distance, pantoscopic angle, wrap angle), reading distance and near mono Pds are optional.

Varilux Ipseo New Edition Lenses are recommended for:

Any Patient who is interested in the most advanced technologies and requires the best optical performance.

> Please note:

Varilux Ipseo New Edition lenses will be supplied with a compensated prescription, so completed orders will highlight an ordered power and measured power.

GT2 Asiana

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

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:

  • Rapid and easy adaptation.
  • Perfect synchronisation of the binocular 3D zones.

 

FrameFit

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.
