Smith I/O's Quick Change Lens System Has Changed the Game

Smith's original I/O goggle is the one that started the excellent I/O line that now features several other goggles. It is truly a breakthrough design that Smith has adopted. The unique offering of the I/O is the dual-hinge quick release lens change system, which we love because it offers a fast and easy lens change with minimal effort. With a few moves, you can quickly go from the bright light lens to your bonus low light lens that is included. With the revolutionary design and bonus lens, the Smith Optics I/O is worth the price. 

You can't talk Smith Optics without talking the highest quality lenses. The I/O includes two spherical carbonic-x lenses with TLT. TLT is Smith Optics answer to decreased visual distortion and resulting eye fatigue caused by light refraction. When light passes through any medium, it changes course. This causes visual distortion. To avoid this, Smith Optics progressively tapers the lens from the center outward to straighten the incoming light rays. This tapering (TLT technology) results in nondistorted, more accurate vision. We noticed the visual difference immediately, and we believe you will, too. 

The I/O also includes Smith's patented porex filter which prevents optical distortion during changes in elevation and 5x anti-fog coating to help keep your vision clear for hours. Smith also designed the I/O with an AirEvac ventilation system that interfaces with your helmet to help circulate air, reducing fogging. 

Sacrificing comfort for design wasn't an option so the I/O has 3-layer DriWix face foam which feels incredible and offers the plush cushioning that gives you all day tranquility. When something isn't broken, you don't fix it, and the Smith I/O goggle has been working well for years.
