You know when you get a splinter in your finger and you dig it out with a needle? Well that's exactly how the medical staff get metal splinters out of your eyeball.
When I got my first job I remember my grandfather telling me the story of the apprentice in his department who decided he didn't need safety glasses when turning brass because it was so "soft".
Long story short, because he was the department head and had a driver's license from his RAF days, he dutifully took said apprentice to the hospital in the works van.
Upon explaining the incident, the doctor charged with treating this misadventure, said something to the effect of "We'd like to help ensure this never happens again, and I know just the thing" and sent one of the orderlies to get someone whilst they prepared for the [medically indicated] eye-gouging.
That someone was the Medical Photographer and his assistant, and following the apprentice being treated about a week later a pack of colour slides for each department in the factory were delivered in the post, marked "Safety Lecture Slides - Eye Splinter"
Apparently the showing of these slides narrated by the apprentice pictured in them resulted in an unprecedented uptake of safety glasses from everyone in the factory (the company provided them free, but at the time [late 60's I think] only apprentices were required to wear them).
Having seen a copy of the slides (via a viewer so not the full effect) I was very much convinced of the wisdom of wearing safety glasses.
Apparently after representations from my grandfather to the factory manager, the apprentice was not disciplined for ignoring the glasses rule on the grounds that it was unnecessary as "Even accounting for the stupidity of a boy fresh from school, no-one would submit themselves to that fate twice”.
I wear a pair of safety specs round my neck all the time, +1.5 or +2.0 depending on what I'm doing. I don't care if it does look a bit poncy, they are always there.
Whilst I don't need corrective lenses, I do the same, out of pure convenience.
I have three sets of relatively nice Peltor glasses with little retaining strings on them, one in the workshop, one in my PPE bag in the car, and one on a hook in my office at work, so they're always to hand.
