Homework Statement
A farsighted man uses eyeglasses with a refractive power of 2.20 diopters. Wearing the glasses 0.03 m from his eyes, he is able to read books held no closer than 0.28 m from his eyes. He would like a prescription for contact lenses to serve the same purpose. What is the correct contact lens prescription, in diopters?
Homework Equations
1/do + 1/di = 1/f
The Attempt at a Solution
well starting off i figured if the power is +2.20 dipoeters then the fd is going to be -1/2.20
not sure but since with the glasses it would be 1/fd-.03? and then with the contacts what would happen since there no distance? I am just really confused now lol
