Offering over a dozen replacement lenses to choose from, the Threshold can be tailored for any light condition.

INSTRUCTION FOR ALL SMITH SLIDER SUNGLASSES: Threshold, Toaster

To remove a lens:

• With the sunglass facing toward you, hold the frame by the nose bridge. Grasp the lens between your palm and your index and middle finger.
• Slide the lens firmly and slowly in an upward motion, rotating it from the inside outward.

To insert a lens:

• Reverse the sequence. Place the outer ridge of the lens in the corresponding frame slot and slowly press down on the top edge of the lens until it slides firmly into place.

EVOLVE Eco-Friendly Green Sunglasses Technology - 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.

Polar-Chromic - 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.

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.

Techlite - 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, and grease.

CR39 - a lightweight advanced polymer that has a high abrasion and scratch resistance. Fashion forward colorations and gradient fades complement excellent optical clarity.
