The all-new I/O combines a wider field of view, innovative Responsive Fit™ frame design, and updated looks. All while using your same proven lens. The spherical lens has 5X™ anti-fog, Smith's highest level of anti-fog technology, and TLT optics for crystal clear vision.Read more
Spherical lenses are built on a base curve in both the X (horizontal) and Y (vertical) axis. Smith's spherical lenses are off ered 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.
Smith's carbonic-x outer lens material is individually molded to off er optimum scratch and impact resistance, increased visual acuity and enhanced contrast sensitivity. The carbonic-x material meets Class 1 optical standards. There is simply no better lens.
TLT: Tapered Lens Technology
When light passes through a medium (a lens, for instance) it refracts, or changes course. This refraction can cause visual distortion and eye fatigue. Smith's Tapered Lens Technology straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. You see with 100% accuracy and maximum comfort.
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.
