Our thinnest lens material
Inherently thin yet exceptionally reliable, Ultra High Index is characterized by optical excellence and style. Recognized internationally* for its outstanding optical qualities and ultra-thin properties, this advanced lens material offers even the most discerning eyeglass wearers a choice of lightweight, elegant lenses.
With a refractive index of 1.74, lenses can be made ultra-thin for aesthetic appeal.
