When Smith created the I/O, they invented a category.
As the original interchangeable goggle, the I/O is the standard by which all other goggles are measured.
When you see more, you can do more. Through the proprietary ChromaPop™ lens technology of Smith , you'll see detail and colour beyond normal capabilities. ChromaPop™ filters light at 2 specific wavelengths. By doing this the lens delivers greater definition, more natural colour, and unmatched clarity to allow you to see more detail. The Chromapop Sun is perfect for cloudless, blazing light conditions, the layered green-mirror over a gray base eases the harsh glare of high elevation sun while helping your eyes see more information in terrain ahead of you.
As early as 1965, Smith pioneered the snow goggle as we know it today. Created to give fanatic shredders more time on the mountain without foggy vision, Smith have dedicated the past 50 years to improving the way we see things. If you aren't gazing at the sun through a Smith lens, are you even gazing at the sun?
