With i.Scription® Technology and ZEISS i.Profiler plus, you can map out each patient’s own visual “fingerprint” and prescribe a lens made just for them, so they see better in daylight and after dark.
Offer your patients the vision correction that suits them best with ZEISS lenses featuring i.Scription Technology. They help cut down glare, bring out richer colour and make contrast crisper. As premium-grade lenses, they also give your practice a way to stand out from others in your area.
Nine in ten patients hope to get back their natural vision and are concerned about the health of their eyes.
Wearers choose ZEISS Individual Single Vision Lenses enhanced with i.Scription® Technology over the same lenses made without it.
Refraction has long been the foundation of spectacle prescriptions, and it happens in two stages:
In subjective refraction, various lens powers are tried out to correct the eye’s refractive errors, such as myopia, hyperopia or astigmatism. These are known as low order aberrations (LOAs).
Pupil size changes with the lighting, though, and that brings other kinds of aberrations into play. They lower the quality of vision the wearer actually ends up with. These are called high order aberrations (HOAs), and examples include coma, trefoil and spherical aberration.
i.Scription® Technology from ZEISS builds on the company’s eye measurement device, the ZEISS i.Profiler® plus. It is made to capture the precise “fingerprint” of a person’s eyes, producing readings that belong to that patient alone.
A ZEISS i.Scription prescription accounts for how low and high order aberrations affect the quality of the image at the retina. To do this, it takes up to 1500 measurement points on each eye. The aim is a vision correction that performs well across a wider span of lighting conditions, including tough situations such as driving at night.
The technology examines the circle of least confusion so that the prescription it produces is as accurate as it can be.
Standard manifest refraction takes place in brightly lit rooms, so the prescription it produces suits daytime conditions. In dim light, though, the pupil widens and the eye’s peripheral aberrations can shift its focus. When that happens, a conventional prescription may stop being accurate.
