This is when the lens in your eye loses its flexibility so it can't adjust shape to change focus any more and it happens to everyone from a certain age.
I'm also about 5 years away from getting to the age where my risk of developing glaucoma increases (and there's family history of it).
I'm also getting new glasses (I meant to do that last year since my prescription had changed enough to warrant it but life got in the way) - at least I'm picking them up next Saturday

Pro tip my friends: don't get old. Just don't get old.
