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.
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 zonesof 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.
