The uniqueness of the human body is one of the many factors influencing product development today, with an increasing demand for products that can adapt to our anatomy.
An overall approach to the eyes and anatomy
The anatomy of individuals differs – and no two faces are alike.
If a spectacle lens is not matched to the wearer’s physiological facial parameters, they may not be able to utilise the full potential of their 3D vision, which is essential for good distance perception. Research shows that 50% of progressive lens wearers experience problems with either clear distance vision, peripheral distortions or limited 3D vision, and/or may also have difficulty judging distances.*
* External market research with 1,000 progressive lens wearers in Germany and USA (2014)
ZEISS Progressive Lens Precision Superb responds to this challenge with a solution that provides an optimum match of the eye-lens-frame system.
Taking into account the physiological position of wearer parameters allows an optimal match of the eye-lens-frame system and therefore full use of three-dimensional vision. FaceFit Technology optimises the vision zones based on the knowledge of the exact position of the eyes and the facial fit of the frame on the nose and ears.
50% of wearers preferred a customised ZEISS lens design versus a standard progressive lens design.**
* External market research with 400 progressive lens wearers in Germany and USA (2014)
** Independent clinical study: Susan C. Han, Andrew D. Graham, Meng C. Lin (Clinical Research Center, School of Optometry, University of California, Berkeley, Berkeley, California). Clinical Assessment of a Customised Free-Form Progressive Add Lens Spectacle (Optometry and Vision Science, Vol. 88, No. 2, February 2011 pp. 234–243), 2011, n=95. In a randomised, double-masked crossover trial, 95 experienced wearers wore ZEISS Individual customised free-form PAL spectacles (test) and standard non-free-form PAL spectacles (control) for one week each
No two faces are alike. Every nose, every ear is different. There is even a difference between the left and right eye. ZEISS Progressive Lens Precision Superb is precisely fitted to the following physiological parameters of the face:
