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

i know i'm missing something because the answer is 44.2+/- 0.1 ...am i completely off with the equation and just got a number similar...?
