Hypermetropia is caused by :

Options

A. low converging power of eye lens
B. low diverging power of eye lens
C. high converging power of eye lens
D. retinal displacement

Explanation

**Step-by-Step Solution:**

1. **Understanding Hypermetropia**: Hypermetropia, also known as farsightedness, is a condition where distant objects can be seen clearly, but nearby objects appear blurry. This occurs due to the way light is focused in the eye.

2. **Analyzing the Causes**: The primary cause of hypermetropia is related to the eye's lens and its ability to converge light rays. If the eye lens has low converging power, it fails to focus light rays from nearby objects onto the retina.

3. **Identifying the Correct Option**: Among the options given:
- Low converging power of eye lens: This is a likely cause of hypermetropia.
- Low diverging power of eye lens: This does not relate to hypermetropia.
- High converging power of eye lens: This would not cause hypermetropia; it would lead to myopia (nearsightedness).
- Retinal displacement: While this can affect vision, it is not a direct cause of hypermetropia.

4. **Conclusion**: The correct answer is that hypermetropia is caused by low converging power of the eye lens.

**Final Answer**: Hypermetropia is caused by low converging power of the eye lens.
