Correct answer and explanation

Correct answer: expansion of eyeball.

Explanation: āœ… Correct Answer: B) expansion of eyeball. šŸ“š Explanation: 'Myopia', or short-sightedness, is often caused when the 'eyeball expands' and becomes too long from front to back. This makes light focus in front of the retina instead of on it. Because of this, a person can see close objects clearly but distant objects appear blurry. This condition is corrected by wearing concave lenses to help the eye focus correctly.
