Options

B. Distant object is focussed behind retina
C. Distant object is focussed in front of retina.
D. Near object is focussed in front of retina.

Answer

**Step-by-Step Solution:**

1. **Understanding Near-Sightedness (Myopia):**
- Near-sightedness, also known as myopia, is a common vision condition where close objects can be seen clearly, but distant objects appear blurry.

2. **Identifying the Cause:**
- Myopia occurs when the eyeball is elongated. This elongation affects how light is focused in the eye.

3. **Analyzing the Focus of Light:**
- In a normal eye, light from distant objects is focused directly on the retina. However, in a myopic eye, due to the elongated shape, the light focuses before it reaches the retina.

4. **Determining the Correct Option:**
- Given the options:
- A) Near object is focused behind retina
- B) Distant object is focused behind retina
- C) Distant object is focused in front of retina
- D) Near object is focused in front of retina
- The correct answer is that a distant object is focused in front of the retina.

5. **Conclusion:**
- Therefore, the eye is said to be near-sighted when a distant object is focused in front of the retina.

**Final Answer:**
The eye is said to be near-sighted when a distant object is focused in front of the retina.
