Surely if your eyes are bad, just wear glasses
Glasses only correct for some things, and you need to admit you need them, and to actually wear them. That seems a very high hurdle for some people.
It seems that a lot of people refuse to go to the opticians until either they have no choice, or something happens which is nuts.
For example the case that seems to be getting a lot of press at the moment was a guy who apparently had trouble seeing his steering wheel...
We had to ban my mother from using her mobility scooter at one point because when my dad went out with her on the other scooter* he realised she couldn't see the traffic, we took her to the opticians who diagnosed bad cataracts and she had an op to remove a few months later.
My sister has glasses, but she doesn't like to admit she needs them, so she didn't wear them when she really should have (she was more or less "ok" without them, but IMO it's stupid to be "ok" when your sight can be "good" whilst driving), she changed a bit when she had her daughter and was a bit more willing to wear them.
I know a few others who admit their eyes aren't as good as they used to be, but "these cheap off the shelf glasses do the job" and won't go to the opticians.
I have a very low opinion of people's common sense when it comes to their eyesight, as so many don't seem to realise or care about it.
Meanwhile I'm mildly paranoid, partly because I've seen how an eye injury (from 70 years ago), cataracts and glaucoma have screwed my fathers' eyes up.
And this reminds me, I need to swap out the spare glasses in the car, they're two prescriptions out

(I always have a spare pair in the car that are good enough to drive in case the ones I'm wearing get broken).
*He's not taken one of the mobility scooters out for about 10 years now, as he decided he wasn't safe on it as his eyes got worse.
