The eye's far point is defined as the farthest point on which the eye can focus. In this example, a nearsighted person has a far point 50 cm away from the eye. What type of lenses should be used to correct vision in this case? What focal length of the lenses will allow the the nearsighted person to focus on distant ( = +) objects? Here you can assume that the corrective lenses are placed right next to the eye.
