i.Scription spectacle lenses involve an innovative patented algorithm which combines the prescription found from your optometrist with the i.Profiler plus ocular wavefront aberrometry data to calculate.
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 expands 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situations, the peripheral aberrations of the eye can lead to refractive shifts that make the conventional prescription no longer valid.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.
