Answer :

Final answer:

Rotate the lens selector dial to bring the object into focus. Option D).

Explanation:

The examiner should rotate the lens selector dial to bring the object into focus in order to indicate that the examination is being correctly performed.

When assessing a patient with astigmatism and nearsightedness, rotating the lens selector dial allows the examiner to adjust the focus and compensate for the astigmatism. This ensures that the patient's eyes are properly examined and the images appear clear and in focus.

By using this technique, the examiner can accurately assess the patient's eyes and make any necessary corrections or recommendations for vision correction.
