Motorcycle goggles have been around for a long time. They evolved from early 20th-century aviation and automobile eyewear that were designed to protect against debris, insects, and wind. In the 1960s, specialized versions were created for motocross and road racing, but they were still an antiquated design, all things considered. Then, in 1980, Oakley – who at the time were known for manufacturing motorcycle and bicycle grips - unveiled the O Frame MX, a new innovation that radically improved protective racing eyewear.
Since then, little has changed, even if the goggle industry would like you to think otherwise. Most off-road eyewear is essentially the same, in my opinion, save for some variation in shape, size, colors, and the lenses available.
But according to 6D, there were five issues with traditional goggles that they wanted to address – an exposed eye port, constant facial pressure, foam that becomes saturated by sweat, your vision being constrained by the frame of the goggle, and the risk of injury due to impact from debris.
