Rachel has good distant vision but has a touch of presbyopia. Her near point is 0.70 m. 

Part A 

When she wears +2.0 D reading glasses, what is her near point?

Part B 

What is her far point when she wears glasses? 

♦ Relevant knowledge

The strength of the lens is due to the fact that the lens is able to easily focus on the subject. The lens’s power is dependent on the distance and close to the focal point in the focal point. The lens’s power is reciprocal that of its focal length.
