Question
- A. The lens becomes thicker
- B. The lens becomes thinner
- C. The lens remains unchanged
- D. The lens changes shape irregularly
Answer
The correct option is The lens becomes thicker. This answer is correct because it matches the approved learning objective to explain that myopia, or short sightedness, is caused when distant objects are focused in front of the retina in the subtopic The eye (biology only).
Explanation
The correct option is The lens becomes thicker. The lens becomes thicker is correct because it directly supports the approved learning objective to explain that myopia, or short sightedness, is caused when distant objects are focused in front of the retina. This belongs to the subtopic The eye (biology only) within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The eye (biology only).
Common mistake
Misunderstanding Myopia
Students often think that myopia is caused by the eye being too long rather than understanding that it is due to distant objects being focused in front of the retina.
Clarify that myopia occurs when the light rays from distant objects converge before reaching the retina, leading to blurred vision for far away objects.
