Tensile
strength（shock
resistant）:Lens with
nano metal oxide role,
impact resistance is about
twice the CR**9,next to PC.
Antifouling(waterproof,grease proofing):a.
Because of
nano metal oxide particles
subtle, closely spaced,
so the lens smooth surface,
the small honeycomb gap(see
byhigh-power microscope),more
be able tobear or endure
corrupt dustproof.b.the surface of lens has the unique nano fight corrupt
membrane,can waterproof,
prevent oil,easy to clean
High
temperature resistant,
anti-aging;Lens in
curing, to be under
**0℃conditions for *4 hours before curing,
So OCCO nano sunglasses high
temperature resistance, ageing resistance level above any other
organic materials lens
