NYX has
teamed with Sved Optics to create the lightest and most

complete sports optical system in existence. The patented (U.S.
Patent
No. 5,790,230) intraSPX™ optical insert can be easily
interchanged between the polycarbonate lenses of the NYX Sport
Vision
System. This effectively gives the sports enthusiast which
need
vision correction lenses the ability to adapt instantly against
changing sunlight conditions.
Prescription Insert Information
Low Profile - intraSPX™ utilizes a patented "lens
suspension"
prescription mounting system that keeps your sunglasses close
to your
face. The system enables the sunglass frame to retain its
fit, comfort, and styling.
Light Weight - The
intraSPX™ system's patented design features rimless prescription
lenses which eliminate the "second frame" common with other systems.
This unique design combined with our exclusive ORAD™ lens grinding
process guarantees you the thinnest, lightest sport optical insert
system in existence.
Versatile - The intraSPX™ prescription insert can
be interchanged between any NYX frame and shield lens combination in
the Carbon and Carbon Pro Series. It is fixed to the Classic
Competition Series. Not available
in the
Ultra-Lite, Talon, Comet, and Arrow Frame Series.
NOTE: The intraSPX™ system is not
available for all prescriptions. If you have a strong prescription,
please
call us at 330-618-8913
to see if yours is compatible with the intraSPX™ system.
How to Order: All NYX
sunglasses are delivered with an easy to understand instruction card
within the foam
lined carrying case. You do not need to
send in the sunglasses when you place your order for the
prescription insert, unless you are ordering the Classic Competition
sports glasses style. These will need to be sent in to
have your prescription actually mounted
to the frame. Simply follow the instructions on the instruction card
and return this
card with your recent eye exam results.
