Smith Optics I/O Medium Snow Goggles (Black, ChromaPop Sun Red Mirror)

Smith Optics I/O Medium Snow Goggles (Black, ChromaPop Sun Red Mirror)

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. The original I/O was the first goggle to solve the problem of what to do when changing light and weather demanded different lenses. The new I/O continues that legacy of uncompromising performance.

Tapered Lens Technology (TLT)

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.

5X Anti-Fog

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.

ChromaPop Lens

Through our proprietary ChromaPop lens technology, we help you see detail and color beyond normal capabilities. ChromaPop filters two specific wavelengths of light that cause color confusion. By doing this the lens delivers greater definition, more natural color, and unmatched clarity to allow you to see more detail.

Porex Filter

Patented Porex filter prevents optical distortion during changes in elevation.
