What brings the strength

① Newly Designed Hard Coat ② Newly Designed Multi Coat

The ultimate resistance to scratches is realized Strengthened by increasing the density
by the new hard coat designed by densifying of the layers and hardening the coating.
the molecules and hybriding the molecules
and corpuscle.
Hardened by hybriding the molecules and corpuscle
to reduce the gaps between the molecules.

Less effect of water, sweat because there is less gap between the layers.

Hardened by increasing the density of the molecules.
③ Special Fluorine Layer
The lens becomes strong to scratches by
reducing the friction of the surface layer with
a special fluorine layer on the top surface.

The Structure of the Coating Strong and Durable

Special Fluorine Layer Tested and proven that there is less
microscopic scratches that can become
visible when used with the scratch
Designed Multi Coat manifestation test.
