As with the Oakley site, they have a section called "Bloody Eye" in the community tab. There, people tell stories of potential severe eye damage that could have occured from not wearing their Oakley eye wear. Yes some of them had some severe facial injuries but they credit their Oakley's to saving their eyesite. About 4 years ago I was doing some work involving the use of 40-45 inch worm drive clamps. These are exactly the same type used in the automotive or plumbing industry for clamping hoses, only these were much longer. They have a quick release swivel on them once they are loosened to ease their removal. I was removing one, and as the tension loosened up it sprung open and then came back striking me in the face, causing me to jerk my head back. When I opened my eyes I noticed a gouge in the center of my left lens in my Oakley Half Jackets. I took off my sunglasses to discover the sharp metal end had gouged and grooved the lens approx. 1/2 inch long and deep. I credit my sunglasses that day to saving my eyesite, as I believe the force of that clamp springing back would have cleary damaged my eye without protection. If you have a story to share, please do.
