New research led by scientists at Cardiff University and the University of Bristol found that people who spend more time in education are more likely to develop near-sightedness. Specifically, researchers found that for every year a person spends in education — where they are likely to spend more time reading and typing on computers — there is a rise in myopic refractive error of 0.27 diopters, a diopter being a standard measure of the optical power of a lens. An estimated 68,000 participants were examined using the "Mendelian randomization" (MR), approach which is often used to examine causal effect of a disease in observational studies.

You are just getting old. It is called presbyopia (see https://en.wikipedia.org/wiki/Presbyopia). [wikipedia.org]

Why are you trying to bring logical reasoning into this?

Sorry, getting old just means your lens becomes less flexible (and possibly the muscles that compress it become weaker). It doesn't make you far sighted, but it means that if you are far sighted you aren't as able to change your focus.
FWIW, I'm nearly to the point where tri-focals would be prescribed, but I don't wear glasses to read a book...only to read a desktop screen. (If I drove, I'd need a separate pair for that, but even with correction I know that I shouldn't drive.)
