The contact lens prescription for a mildly farsighted person is 0.75 D
The contact lens prescription for a mildly farsighted person is 0.75 D, and the person has a near point of 29.0 cm.
Randomized Variables
Pe = 0.75D
What is the power in D of the tear layer between the cornea and the lens if the correction is ideal, taking the tear layer into account? Assume that a normal human has a near point of 25.0 cm.
