Presbyopia and myopia are not opposite; in fact, you can have both at once! My mother has to wear bifocals for precisely this reason.
> Presbyopia (from Greek presbys (πρέσβυς) = old man + ops (ὤψ) = see like, sight > meaning literally trying to see as old men do[1]) is a condition associated with aging in which the eye exhibits a progressively diminished ability to focus on near objects.
