If you can't see far away that's called nearsightedness. If you can't see well close up then you're farsighted. Most people become farsighted as they age and need reading glasses; that's because your eyes change shape as you age. I had been nearsighted for most of my life and I needed glasses for that. Of course when I was wearing those glasses things up close were blurry. I used graduated lenses so I wouldn't have to keep taking my glasses on and off. Weirdly--but not uncommonly--I lost my nearsightedness when it became harder and harder to read. Now bifocals work perfectly for me.

Cogentin at a dose of 3mg blurred my close-up vision enough that I couldn't even see to read with glasses. When I stopped taking it that went away.
