Final answer:
Explanation of how to calculate the power of a lens needed to correct a patient's vision based on their near and far points.
Explanation:
The power that should be prescribed to correct the patient's vision can be calculated using the lens formula:
Power = 1 / focal length in meters
Given the near point and far point of the patient, the prescribed power would be:
Power = 1 / (near point - far point) in meters
