The correct answer is: The side of the lens where the add power if etched

The other options are incorrect because they do not accurately describe the side of the lens where the add power is etched. Option A refers to the diopters of power provided to the eye, not the side of the lens. Option B describes a patient's eye movement, not the side of the lens. Option D is another term for a different tool and not related to the side of the lens. Only option C correctly identifies the side of the lens where the add power is etched.
