complement to the Touchstone, the Smith Optic Backdrop Polarchromic Sunglasses
encompass the same great features like spring hinges and Megol covered contact
surfaces. Sharp detailing showcases a medium coverage lens profile that makes it
perfect for the leisure activity of your choice.
- Smith Optics Polarchromic lens technology combines the benefits of glare
obliterating polarization with the advantage of photochromic light sensitivity.
Available in either Carbonic or Techlite glass, Smith Optics Polarchromic lenses
automatically self-adjust their tint in response to ambient UV light conditions
creating a tint level which is perfect at all hours of the day. These lenses
retain their photochromic properties indefinitely, certainly outliving the life
of the frame itself. Spanning a range of approximately 10%-35% VLT (Visible
Light Transmission) Polarchromic lenses need only 10-25 seconds to fully
transform from light to dark depending on UV light intensity. The result is a
lens tint which is perfect at every moment of the day from dawn to dusk
particularly at hours when the benefits of polarized are vital but the lens tint
has to be light enough to see.
- Crisp, brilliant optical acuity in an ultra lightweight glass lens. Smith
Optics Techlite Glass Polarized lenses deliver the highest level of visual
clarity and scratch resistance with distortion-free performance.
Technology (TLT) -
Visual distortion occurs when light waves hit an aggressively-curved lens
causing it to bend or distort an objects true size or position. Imagine looking
through a fish eye lens. What your eye normally sees, is stretched beyond
reality. Get the picture? Tapered Lens Technology corrects the distortion by
progressively tapering the lens from the optical center towards the out edges.
Light waves are thereby delivered straight to your eye resulting in zero
distortion and true optical clarity. What you see is what you get.
Frame - Resilient,
tough and flexible. Grilamid is an exceedingly light and durable plastic that
will maintain its shape under any temperature changes.
8 Base Lens
Combining just enough head curve and optical centration to protect you from the
elements. The 8 base’s mellowed wrap angle keeps you looking chic. Take ‘em off
and you’re on your own.
