Lemond is famous for being able to see through solid material to examine its internal structure.
Why not? Don't your sunglasses pass the EN for impact protection like my cycling glasses do?
...but it amazes me when people get all fussy about protecting hard skull yet leave soft squishy eyeballs unprotected and lots do that. Is crash helmet promotion overshadowing more worthwhile protective equipment?
Very true. In 8 years of cycle training I've never had any one suffer a head injury, but several with eye injuries from low hanging branches, grit, insects etc. I insist on eye protection for my students if teaching an off road element, and always wear it myself off road.
I don't wear them on road. I'm a sweaty betty and suffer with them steaming, so its a choice of an eye injury or getting killed because I couldn't see where I was going. Off road, lower speeds, less physical exertion, doesn't seem to be a problem.
