Responsive Fit design allows the frame to adjust and flex to the contours of your face. Every face is different. By reducing material and creating a flexible lattice architecture, Smith's frames act like a suspension system that micro-adjusts to your unique facial structure, assuring a precise, comfortable fit.

Spherical lenses are built on a base curve in both the X (horizontal) and Y (vertical) axis. Smith's spherical lenses are offered exclusively in carbonic-x material with TLT Optics and a base 6x4 toric shape. This pioneering shape provides the highest level of optical clarity, improved fit characteristics and increased volume, improving fog performance.

Cylindrical lenses are built on a base curve in only the X (horizontal) axis. Smith's cylindrical lenses are offered in carbonic-x material with and without TLT optics and a base 6 curve. Providing Class 1 optical standards and optimum fit characteristics.

Smith's Tapered Lens Technology straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with 100% accuracy and maximum comfort.

Smith's carbonic-x outer lens material is individually molded to offer optimum scratch and impact resistance. The carbonic-x material meets Class 1 optical standards. There is simply no better lens.

Our Fog-X lens treatment employs a hydrophilic, micro-etched surface to absorb moisture and disperse it over a wide surface area to prevent fogging. Because it is physically carved into the lens, it can't be wiped away like other anti-fog coatings.

A durable coating bonded to all mirrored lenses that 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.

The most advanced anti-fog lens ever created. Building upon the hydrophilic, micro-etched surface area principles of our Fog-X lenses, our revolutionary 5X anti-fog inner lens has been engineered to provide over five times the absorptive properties of anything on the market. Initial testing showed standard anti-fog lenses fogging between 30-50 seconds. Smith's proprietary 5X anti-fog treatment withstood fogging for over 120 seconds in controlled lab tests.
