I bet nearly everyone who actually did break their lens said that same thing.
I've never used UV lenses barring a few cheap ones in the beginning and have never had any damage (I've been caving, hiking, etc with my gear) because I use the amazing LENS CAP.
In all seriousness, lens caps are the way to go. I bought a few lens cap leashes as well, and they are extremely useful. It's one of those things you never really care about until you actually have them. No lost caps for me!
