Ultra High Index
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.
This material makes it particularly suitable for patients with a higher plus or minus prescription, reducing the magnification effect caused by thicker lenses. Available with all of our premium progressive and single-vision lens designs and coatings, Ultra High Index is extremely lightweight, which increases comfort.
* Ultra High Index was the winner of the International Forum Material Award in 2011
