Optical Dynamics is pleased to announce the
availability of its new nanoGUARD™ Super Scratch Resistant
The nanoGUARD™ Hardcoat is a dual–layer
coating consisting of one layer of nano-XT coat plus one layer of
nanoGUARD™ coat applied to both the front and back surfaces
of the lens. The nanoGUARD™ Super Scratch Resistant Coat uses
Optical Dynamics’ nanotechnology-based in-mold coating method
to form a nanocomposite layer on the surface of the finished lens.
First, a thin layer of nanoGUARD™ coating
that contains a high concentration of extremely hard nanoparticles
is applied to the casting surface of the mold and cured. Next, a
thicker layer of nano-XT is applied to the first layer and cured.
The coated mold is then used to cast the lens and when the mold
is removed, this nanocomposite coating transfers to the finished
