ZEISS VISUFIT 1000 is a new digital platform that will:

ZEISS Visufit 1000 at Cliff Williams Opticians in Kirkcaldy, Fife, Scotlandoffer highly accurate 3D centration for your new spectacles.

Ensuring accurate centration to maximize optical performance.

Enable us to guarantee that bespoke lenses and frames fit you perfectly.

Provide clear images of frames to help you choose a frame style.

Enable us to carry out a consultation based on your specific needs.

Provide easy customisation for your spectacles, sunglasses and drivesafe lenses.




Measuring pupil position with felt tip pens


Are traditional  manual centration methods the ideal solution for your needs?

Surely there is something more modern than putting a felt tip smudge on the dummy lenses?

Inaccurate centration can lead to a 40% reduction in the performance of a lens.

It can also be difficult to see the new frame styles clearly before ordering.

High Accuracy using 3D

3D centration is done by using 9 mutually calibrated cameras to give a complete 180° view in just one shot. Our Patients will notice this upgrade as we will not need to use the frame calibrating clip as we have done previously.

To assist with accuracy the VISUFIT 1000 has a laser speck as a projection to infinity to focus on which makes data reliable.

Right and left back vertex distance determination provides an unprecedented level of accuracy in the calculation of the lens design, taking individual wear parameters into account.

Using our PC or our iPad, we can manage the centration device is easily and quickly, keeping you at ease throughout the quick process.

Our body posture assistance will help us correct any unnatural body posture that can affect the centration process.

Frames with thick temples are no longer a problem as the overlay function will help us detect the position of the cornea and determine the back vertex distance without trouble.

Interested to know more about the process and what digital data goes into bespoke lenses? Read on:


For many years the use of plastic rulers and felt tip pens has been the way of finding where your pupil position is in relation to the middle of the frame and the bottom of the frame, but this can create many different problems and errors throughout the process, from simple errors to height differences between you and the person taking the measurements or excessive head rotation. We have progressed from the ZEISS Relaxed Vision Terminal, to i.Terminal 2 and now with ZISS VISUFIT 1000 we can gather the following measurements:

Zeiss i.Terminal digital facial measurements

When we are measuring you for the latest Carl Zeiss Individual single vision or progressive lenses we can quickly gather the following information, which you can see in the picture above and in detail to the right:

i.terminal measurement data close up

Monocular Pupil distance (PD)

The distance from each pupil to the centre of your new frame

Vertical Height (Y)

The distance from the bottom of the frame to the centre of your pupil

Pantoscopic angle (Panto)

The amount that the frame tilts in towards the cheek

Back Vertex Distance (BVD)

How far the back surface of the lens is from the front of your cornea

Bow angle

How much the frame front is curved - or frame wrap

What's more when we are designing your new ZEISS Individual ® Eyefit lenses - customised progressives - we can position the lower reading area (marked with the thick yellow circle seen in the picture above) so it is inside the frame, maximising your reading zone to the spectacle frame depth you have chosen!

We then enter the additional details to fully customize your Eyefit lenses:

Reading position

How far away you like to do close work, or hold your reading material as we are all different sizes and have different needs.

Personal near vision use

Together we establish whether a lens design tailored for near vision, intermediate vision or balanced where you lead an active lifestyle at varied positions throughout the day is best for your individual needs.


But that's not all!

Finally Carl Zeiss engrave onto the front surface of all ZEISS Individual ® Eyefit progressive lenses your personal initials to show that both sides of your lenses are unique to you, not just the back surface, with no compromised moulded lens designs. Your engraved initials on Eyefit lenses are very subtly done and can be detected with a trained eye and the correct lighting.

With all these measurements taken we then connect directly to Carl Zeiss Vision in Aalen, Germany where the data is transferred digitally ready for us to complete your order, this means that your measurements are sent to the lab correctly.


What happens if my measurements are taken with rulers and felt tip pens?

Studies by Carl Zeiss Vision suggest that if a lens is incorrectly centred by as little as 1.0mm then up to 50% of the intermediate and near vision areas are compromised, resulting in a narrower intermediate and reading area, which can be annoying as you lead your daily life.
