Wondering what Smith Optics' technical terms mean?
Here's a list of definitions to help you become more technically
savvy. Please note: Not all Smith Sunglasses feature all
of these technologies. Please check the "Technical Details" tab to
see which features your sunglasses come with.
Evolve (Eco-Friendly / Green) Sunglasses
By utilizing a new material called Rilsan Clear,
Smith Optics is creating lightweight, durable, and fully transparent
sunglass frames that are over 53% bio-based. Created from easily
renewable, non-genetically modified castor plants, Rilsan Clear
frame is combined with FSC certified packaging and a coconut fiber
storage bag. Not to be forgotten, each logo plaque is "finished"
with a clear water-based protective coating. The end result is a
fully considered sunglass and a clearer conscience.
A lens technology combining 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.
It's like noise-canceling headphones for your
eyes. Glare off of horizontal surfaces like snow, water, and
asphalt, decreases depth perception, reduces visual acuity, and
causes eye fatigue. We precisely align the polarized visual layer
inside our lenses to filter out 99.9% of this "visual static" for a
finely tuned view of the action.
Lens Construction -
The glare stopping
benefits of polarization meet tint shifting photochromic magic in
the most advanced lenses we have ever created. Versatile and
comfortable, Smith Polarchromic lenses automatically darken or
lighten as a response to the level of light you are exposed to.
These polarized, variable tint lenses darken on exposure to
ultraviolet (UV) radiation. Once the UV is removed (for example by
walking indoors or having the sun drop behind the tree line), the
variable tint lenses will return to their lighter tint state.
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.
Polarized Glass lenses produce clarity, optical
precision, and comfort that surpass all expectations. By absolutely
minimizing lens thickness to provide a 20% weight reduction over
standard lenses, total frame weight rivals any sunglass on the
market. Created through a finishing process with controls
maintaining 1/200th of a millimeter tolerance, each lens is
optically-corrected using Tapered Lens Technology. Utilizing a nine
layer construction set up, all available light is managed to
maximize clarity and eye comfort. All Techlite Polarized Glass
lenses utilize a multi-layer Anti-Reflective (AR) mirror coating to
absorb back light effects. A permanent Oleophobic coating protects
the lens and mirror coatings by repelling water, dirt, fingerprints,
- Unsurpassed impact and scratch resistance. Impact
resistant polarized optics providing great value and glare
- Engineered to be the most impact resistant
lens material in the world, Carbonic TLT lenses are optically
corrected to maximize visual clarity and object definition. Carbonic
TLT polarized and non-polarized lenses are ideal for sport and
Brilliant optics meets modern fashion. A lightweight
advanced polymer that has a high abrasion and scratch resistance.
Fashion forward colorations and gradient fades complement excellent
Hydroleophobic Coating -
An advanced lens barrier engineered
to never stop repelling contaminants and moisture. Repels moisture,
grease, and grime. A barrier between your lenses and the world.
Water will bead up and disperse without streaking. Smudges from
fingerprints are wiped clean easily.
