Question
- A. It diverges light rays
- B. It converges light rays
- C. It reflects light rays
- D. It absorbs light rays
Answer
The correct option is It diverges light rays. This answer is correct because it matches the approved learning objective to describe how spectacle lenses correct myopia and hyperopia by changing the refraction of light before it enters the eye in the subtopic The eye (biology only).
Explanation
The correct option is It diverges light rays. It diverges light rays is correct because it directly supports the approved learning objective to describe how spectacle lenses correct myopia and hyperopia by changing the refraction of light before it enters the eye. 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 Lens Function
Students often confuse how spectacle lenses correct myopia and hyperopia, thinking they simply magnify or reduce size rather than changing the refraction of light.
Emphasize that spectacle lenses adjust the path of light entering the eye to ensure it focuses correctly on the retina, rather than just altering the image size.
