Between ages 40 and 50, you begin to lose the ability to accommodate (focus up close by muscles causing the lens to become rounder. As we, shall I say “mature”, the lens loses that ability.

So my guess is that you are somewhere in that age range, and still have the ability to do that to some degree.
