The extra-large spherical lens of the I/OX allows unparalleled peripheral vision, while 5X anti-fog technology provides five times the fog absorption compared to anything else on the market. This technology combined with the interchangeable lens keeps you on the mountain all day, regardless of the conditions.

Quick release lens change system
Includes bright light and low light performance lenses
Spherical Lens: Spherical lenses are built on a base curve in both the X (horizontal) and Y (vertical) axis. This pioneering shape provides the highest level of optical clarity, improvied fit characteristics and increased volume improving fog performance.
5X Anti-Fog Inner Lens: The most advanced anti-fog lens ever created. Building upon the hydrophilic, micro-etched surface area principles of Smith's Fog-X lenses, the 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.
Tapered Lens Technology: When light passes through a medium it refracts, i.e. changes course. If left uncorrected, 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. What this means for you is that you see with 100% accuracy and maximum comfort.
Porex Filter Technology: Changes in elevation bring changes in atmospheric pressure. These forces have the potential to diminish the optics of thermal lens systems. Smith's patented Porex filter solves this issue by allowing the air pressure within the sealed lens chamber to equalize with the ambient atmospheric pressure ensuring class 1 optical standards.

Only use Smith goggles for past 15 years. Phenom back in the day, then Vice the past few years. Chromapop works, have a pair of Oakley Flightdeck with Prizm and I find Chromapop to be way better than Prizm. I/OX is the best fitting M/L goggle I've had yet with great peripheral vision. Big thumbs up.
