But it's not about purchase price (more the faff of obtaining, carrying, wearing and so on), Bolle lenses are lumpy, and your eyesight wasn't significantly at risk to begin with!
Yes, there's a small chance of a freak incident, but the main reason to wear them is comfort if you need them. If you can ride without messing about with extra glasses, why wouldn't you?
Okay so price isn't the issue for you any more, now you've seen they're dirt cheap. Now it's the faff. But to order online is something like a one/two minute exercise, and usually they're here the next day, maybe the one after. Faff to carry? You wear them on your face, no need to carry them. Faff to wear? Again, you wear them on your face, not hard. They're not uncomfortable, and you don't notice them once on, so no faff there.
Your other issue was Olympification (which I also have to give you cred for inventing!) They're not dear, and not particularly sexy. How are we Olympifying eye protection here?
You say there's a small chance of a freak incident... you're right to an extent, but why wouldn't I want to eliminate that risk entirely?
You also say the main reason to wear is comfort... I agree. Why would I want my eyes to be uncomfortable, red and streaming?
