What is the characteristic symptom of nearsightedness (myopia)?
Options
A The near point is too far away.
B The far point is too close.
Correct Answer
C Light is focused behind the retina.
D The lens-cornea combination is not powerful enough.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 41 states: 'Nearsightedness: far point is too close.' Page 42 further elaborates that 'Short-sighted people can focus on nearby objects, but cannot focus on distant ones. The far point is nearer to the eye than infinity.'

Hint

Nearsighted individuals have trouble seeing distant objects clearly. What does this imply about their 'far point'?
