Myopia is caused due to

Options

A. the high diverging power of the eye lens.
B. the high converging power of the eye lens.
C. the blind spot on the retina.
D. None of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Myopia**: Myopia, also known as nearsightedness, is a common vision condition where distant objects appear blurry while close objects can be seen clearly. This occurs when the eye is too long or the cornea has too much curvature, causing light rays to focus in front of the retina.

2. **Identifying Causes of Myopia**: The main causes of myopia include:
- An elongated eyeball (the distance from the front to the back of the eye is too long).
- An increase in the converging power of the eye lens (the lens is too strong).

3. **Evaluating the Options**:
- **High Diverging Power of Eye Lens**: This is incorrect for myopia. High diverging power is associated with hyperopia (farsightedness).
- **High Converging Power of Eye Lens**: This is correct. In myopia, the lens has a high converging power, which causes light to focus before it reaches the retina.
- **Blind Spot on Retina**: This is incorrect. The blind spot is a normal part of the eye where the optic nerve connects to the retina and does not cause myopia.
- **None of the Above**: This is incorrect because we have identified the correct cause of myopia.

4. **Conclusion**: The correct answer is that myopia is caused due to the high converging power of the eye lens.

**Final Answer**: Myopia is caused due to high converging power of the eye lens.
