This is sculpture mixed with science, and there’s
a reason behind every curve. The side-to-side contour of a lens can make or
break peripheral vision. Scalpel has a full 8.75 base curvature to open your
range of view. That much of a contour leads to optical distortion in ordinary
sunglasses but Scalpel is engineered with XYZ Optics to maintain critical
clarity along the entire lens curve. You’ll have added protection against sun,
wind and side impact. As a matter of fact, this design meets ANSI Z87.1 basic
impact standards, and the pure Plutonite lenses filter out 100% of all UV. The
optics also meet every ANSI Z87.1 standard for visual performance. So if you hit
the links or just crash a beach volleyball game, Scalpel will give you all the
razor-sharp clarity you need. The smooth sculptural contours are made of
durable, lightweight O Matter frame material, and the stem sleeves have been
given special attention. Note how they wrap the ends and continue along the
underside. They’re made of Unobtainium, a material that increases grip with
sweat, and they’re part of a Three-Point Fit that maintains comfort all day
while holding the lenses in precise optical alignment.
