You meet a person with prescription glasses of +1.74 dpt.
What is the near point of this person? Express the result as a positive number!
Hint: the near point of a healthy person is 25 cm. An object placed at this distance will form an image at the near point of the person.
1.74=-q/p
-q=(25)(1.74)=43.5
