There is one other major factor which can impact a person’s near vision after head trauma that is termed Convergence Insufficiency. Without getting too technical, to have your eyes focus up both eyes need to turn inwards slightly (converge). If the eyes remain perfectly aligned- like looking at a distant road sign- they would be unable to focus on a fingertip. Thus, the brain unconsciously pulls the eyes in to focus on the near target.
