Consider a person whose eyes can only focus on objects that are further away than 2 meters . Therefor the maximum power his eye can reach is D=1/do + 1/di = 1/2 + 1/.02 = 50.5D . He would like to get glasses that would allow him to see objects as close as 0.25 meters. For this the combined power of his eye and glasses would need to be D=1/do + 1/di = 1/.25 + 1/.02 = 54D What is the power of the glasses he needs to ask for? Group of answer choices 3.5 D 104.5 D 50.5D 54 D
