If I'm in an environment where I'm likely to break my glasses, I want to be wearing some kind of protective eyewear - a scratched eyeglass lens is a lot easier to replace than a scratched cornea. Wraparound safety glasses are comfortable, extremely durable and can do double duty as sunglasses.
Oh, well, my vision is not that bad. I suppose if I could barely see when getting out of bed in the morning then perhaps I would consider it more seriously. I only had to get them because I failed a drivers vision test but just barely.
Also if you do the math it can potentially save you money on contacts and the ever-obnoxious eye checkups.
9 years since I had it done and it is amazing. No regrets so far.
I get out of bed every day and I can just see. No searching for glasses or going to the bathroom to put contacts in.
