The use of the nanocomposite technology has improved the scratch
resistance of Supra coated lenses against both light abrasion and
deep scratching. Because of their surface hardness, derived from
the polymerisation of polysiloxane compounds, Supra coated lenses
require no special precautions. Nevertheless, cleaning with a tie
or scarf etc, and leaving spectacles on a desk lens down or in an
excessively hot place, should be avoided.
Supra is applied as standard to Orma 1.5, Ormix 1.6 and Airwear 1.59 lenses. These lens products are not
tintable after the application of Supra.
The Supra coating offers the following benefits:
High stratch resistance on both sides of the lens.
An excellent adherence.
