A near-sighted person has a far point of 75cm. That person gets corrective glasses, which rest 2cm from their eyes, in order to give them a normal far point that is infinitely far away. However, those corrective lenses don't just change the person's far point. While wearing their glasses, what is this person's new near point (assume that without glasses, their near point is the normal 25cm)
