At age 40, a man requires contact lenses (f=65.0 cm) to read abook held 25.0 cm from his eyes. At age 45, he finds thatwhile wearing these contacts he must now hold a book 29 cmfrom his eyes. What focal length lenses does he require atage 45 to read a book 25 cm from his eyes? By what distance has his near point changed?
