Light blue coating is that filters out specific wavelengths of blue light from reaching the patient's ocular tissue.
It is base on Anti-Reflective coating, similar to standard AR treatment, except it is specific to filtering out the narrow band of blue light from 415-455(nm) which has been studied and understood to impact circadian rhythm and potentially impact the retina.
Incorporated into the AR layer of Glacier Achromatic UV, is a unique, enhanced, and transparent layer with powerful anti-static properties that keep the lenses dirt and dust-free.
Due to its specially developed super-slippery composition, the coating is applied
in an innovatively thin layer that is both hydro- and oleo-phobic.
Its perfect adherence to the top of the AR and HC coating stack results in a lens that is also effectively anti-smudge. That means no more hard-to-clean grease or water spots that interfere with visual acuity.
A dual-lens protection process provides lenses with an extremely hard, scratch-resistant coat that is also flexible, preventing lens coat cracking, while protecting the lenses from the wear-and-tear of everyday use.
And because it offers superior protection, it enjoys an extended warranty.
Blue light reducing lenses are created using a patented pigment that is added directly to the lens before the casting process. That means the blue light reducing material is part of the entire lens material, not just a tint or coating.
This patented process allows blue light reducing lenses to filter a higher amount of both blue light and UV light.
