Homework Statement
A myopic person has a far point of 150cm and can see objects clearly at 20cm near point. What is the object distance?
Homework Equations
Thin lens equation 1/f =1/d1-do.
The Attempt at a Solution
di = -150cm because it's on the left of the lens. do = should = infinity, but I needed to know what the actual object distance is...beyond the myopic farpoint. I'm not sure that the 20cm near point is relevant. Does this mean that the actual object distance is do=1/0 and rearrange to find the actual object distance. However I'm not sure how this would work.
