Ranges of vision in progressive lenses

A progressive lens features three ranges of vision: the distance, progression (intermediate) and near zones. The transitions between the zones are flowing and invisible from the outside.

Schematic representation

Distance zone: For far vision. This is designed so that distant objects can be seen in sharp focus.
Intermediate range: This creates a flowing, comfortable transition between the far and near ranges. Here you will enjoy clear vision with your eyes slightly lowered.
Near zone: This sharply images close-up objects. Therefore, you can read comfortably with your eyes fully lowered.
In the highlighted peripheral zones of the progressive lens there are areas of minor blurring which cannot be avoided but are so small that they are barely noticed by the wearer, or only during the initial adaptation phase.

Individualised progressive lenses from Carl Zeiss Vision

On the basis of the measured prescription and fitting data every ZEISS progressive lens is individually computed and tailor-made for each individual case.

ZEISS progressive lenses are characterised by very large usable ranges of vision – also for non-standard data.

Unlike traditional progressive lenses, ZEISS progressive lenses guarantee maximum usability of the ranges of vision. See for yourself!

Simple progressive lens

Limited range of vision, particularly for far and near vision. Longer adaptation. Reduced visual comfort.
The world is too beautiful to see through a small keyhole!

Modern multipurpose progressive lens

Large, usable ranges of vision for distance, middle distance and near. High degree of immediate wearer tolerance. Increased visual comfort.

Tailor-made Individual® FrameFit® progressive lens

Largest possible ranges of vision at all distances and for every lens power. Individualised solution instead of a standard product. Maximum visual comfort right from day one.

Special purpose progressive lenses

We recommend special purpose progressive lenses to meet the constantly changing demands made on your vision at work. These are specially designed for middle distance to near vision and do not feature a fully correcting distance power in the upper area of the lens. Such a special purpose progressive lens (clear vision up approx. 3 m) offers the benefit of full freedom of movement within a room. Compared to multipurpose progressive lenses, these provide you with wide fields of vision for all indoor activities.

With a standard pair of reading glasses your vision is very limited; with reading spectacles featuring extended ranges of vision you can see clearly within desktop distance; with progressive lenses you can see across the entire room.

Progressive lenses at a glance

The range of lenses from Carl Zeiss Vision offers various possibilities for the presbyopic wearer:

  • Dynamic reading lenses for prolonged activities at near and intermediate distances (up to about 1.20 m).
  • Special purpose progressive lenses for all indoor activities ( clear vision to approx. 3 m)
  • Progressive lenses for all-round use if near and distance vision are equally important, e.g. for driving or when you are out for a walk in a city.

Your personal progressive lenses

The exact measurement and allowance for the wearer's personal parameters are the most important criteria for the production of your personal progressive lenses.
The more personal data can be taken into account, the larger your visual ranges will be for totally relaxed vision and excellent visual comfort.

These dimensions and data are determined:

  • Interpupillary distance: the distance between your two eyes. And the distance of each individual eye from the centre of your new frame.
  • Viewing height: measurement of the height at which your right and left eyes each look through the new frame.
  • Inclination of the frame (pantoscopic angle): the degree to which your frame is inclined forwards relative to the perpendicular.
  • Distance between the eye and the spectacles (back vertex distance): this indicates how many millimetres the lens is away from your eye.
  • The curvature of the frame (frame wrap): your frame is slightly curved in order to match it to the shape of your face. This angle is measured.
  • Dimensions of the frame: measurement of the length, width and height of the frame with millimetre accuracy.
  • Personal visual behaviour: determining for what visual tasks you will be using your spectacles at work and/or in your leisure time.
  • Personal reading behaviour: your personal reading/working distance is also taken into account in the optimization of your lenses, e.g. how close to your eyes you hold a book.
