ZEISS i.Scription

ZEISS i.Scription® Technology

The next Generation of Lens Optimization

The human eye is a true marvel of nature. Seeing is not just seeing. The visual process encompasses many different aspects, all influenced by the eye of the beholder.

i.Scription® at a glance

  • Detection of higher-order aberrations through the use of wavefront technology.
  • Scientifically valid algorithms for individualized lens computation
  • Result: optimization of the image on the retina for optimum visual quality and contrast in different conditions
  • Design

    With i.Scription® colors are richer than ever before, night and twilight orientation is possible without reflections or haloes, and everything is seen with breathtaking sharpness – all with outstanding contrast and clarity.

    Vision with i.Scription®

    This is all achieved through the exact measurement of i.Profiler®plus and an innovative optimization algorithm which takes into account the individual aberrations of the eye - including higher-order aberrations. Newly developed, highly precise production processes turn these calculations into lenses that allow a perfect view of the world.

    High-tech for higher order aberrations: ZEISS lenses with i.Scription®

    In the field of optometry, the refractive errors of sphere (defocus) and cylinder (astigmatism) comprise aberrations of up to the second order. These aberrations can be corrected by spectacle lenses. Higher order aberrations of the eye - such as coma or trefoil - cannot be corrected with spectacle lenses, as they are dependent on the pupil aperture and therefore to a major extent on the viewing eye. However, they have a major influence on the quality of the retinal image: higher-order aberrations are the cause of reduced visual contrast or poor vision in night or twilight conditions.

    With i.Scription®, Carl Zeiss has now developed an optimized algorithm that takes into account higher order aberrations in order to optimize the corrective power of the lens.

    i.Profiler®plus data become i.Scription®

    The most important component is the data calculation with the computer system at Carl Zeiss – the result of many years of intensive research. Thanks to the extensive experience gained by ZEISS in refractive surgery, this technology can now be utilized in the field of eyeglasses.
