ZEISS Precision lenses with i.Scription® Technology
The outcome is the key
i.Profiler®plus does not only provide you a better prescription, it gives you access to an optimised individualised lens solution with i.Scription technology for improved colour and contrast vision as well as improved night vision. i.Scription involves an innovative patented algorithm which combines the subjective refraction values with the i.Profiler plus ocular wavefront aberrometry data to calculate an individualised prescription to 1/100th of a dioptre - especially for lower light situations.
With customised i.Scription® lenses, your patients benefit from:
Better night/ low-light vision:
Looking directly at a light source at night, such as car headlights, results in glare and halo effects. i.Scription technology reduces image noise.
Better visual contrast:
Seeing contrast, such as white letters on a black background, is especially challenging for the eyes. i.Scription technology sharpens contrast.
Better colour vision:
i.Scription technology adds more brilliance to life and lets lens wearers see colours as they really are: bright and more intense.
i.Profiler® plus enables i.Scription® technology through precise, automated measurement of your patient´s visual profile.
Using Wavefront technology
the i.Profilerplus generates a detailed visual profile of both eyes in just 60 seconds.
A harmless beam of light
enters the eye to measure how light passes through it to map higher order aberrations with up to 1500 sample points, which are responsible for decreased performance in night vision. This process will take place in a few seconds while your patient is focusing on the image of the hot air balloon presented by the i.Profilerplus.
involves an innovative, patented algorithm which combines the subjective refraction values with the i.Profilerplus ocular wavefront aberrometry data to calculate an individualised prescription to 1/100th of a dioptre – incorporated in a ZEISS lens with i.Scription technology.
Why is i.Scription® technology particularly beneficial in low light conditions?
Conventional manifest refraction is performed in well illuminated rooms, leading to prescription values that work well in daylight situations. However, as the pupil enlarges in low light situations, the peripheral aberrations of the eye can lead to refractive shifts that make the conventional prescription no longer valid. i.Scription® technology is able to combine the information about peripheral aberrations provided by i.Profiler® plus together with manifest refraction, resulting in an optimised prescription to provide better day and night vision.
