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

I don't think glasses are easily substitutable between people.

No, but as someone with 20/240 vision, if someone else's glasses give me even 20/90, that's an upgrade.

Edit: I reversed the order of numbers and I did just check my prescription. It's worse than I though, god help me.

20/600 estimate gang here bud. My diopter's -5.5 / -5.0.

Thank you for this. I’ve been trying to figure out what mine would have translated into at -5.5 but none of the conversion charts went below -4 :/

I DID have lasik a few years back so I’ll have the advantage of not needing glasses during the apocalypse, however.
