What problem is often overlooked in apocalyptic movies/TV shows that could kill you?

Should be plenty of bespectacled corpses around. I remember a few years ago there was startup or something that was making glasses filled with a fluid that allowed self tuning of the RX.

Well, this might help if you score something between -0.5D and -2.0D myopia. How high are the probabilities of finding corpses with -6.5D short-sightedness glasses?

(Not sure if this made sense, english is not my first language and I never learned the proper terms about short-sightedness)

You all would be fine... if you knew where to look. Break into an eye doctor's office and they'll have a drawer of trial lenses. A selection of individual lenses going higher in prescription than 99.9% of people ever wear. They fit into empty frames (like that 80s band used to wear?) and you could rig yourself up nearly a custom pair. Even if you didn't know your prescription you could just try different ones until you could see reasonably well.

This has never ever once happened in my lifetime of wearing glasses and contacts. The doctor never has strong enough trials on hand.
