Question
Which of the following is a direct consequence of astigmatism, as described in the text?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The text explicitly states: 'As a result [of astigmatism], horizontal lines may be imaged in a different plane from vertical lines. Astigmatism may make it impossible, for example, to focus clearly on the horizontal and vertical lines in a picture at the same time.'
Hint
Astigmatism is related to different focal points for different orientations of light.
