As a treatment for cataracts (a cloudiness of the lens of the eye), the natural lens is removed and a plastic lens is implanted. After this is done a person can see distant objects clearly, but he cannot accommodate to focus on nearby objects. If for example such a person wanted to read a book at a distance of 25 cm, he would have to wear eyeglasses whose diopter power was approximately
a) -1.78 diopters
b) -4.00 diopters
c) +2.78 diopters
d) +3.33 diopters
e) +4.00 diopters
