Options

A. Do not enter the eye at all
B. Come to a focus at back of retina
C. Come to a focus in front of the retina
D. Come to a focus in between retina & iris

Answer

**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 condition occurs when the eye is longer than normal or has a cornea that is too curved.

2. **Light Rays and Focusing**: In a normal eye, light rays from distant objects focus directly on the retina. However, in myopia, the light rays do not focus correctly.

3. **Where the Focus Occurs**: In myopia, the rays of light from distant objects converge and focus in front of the retina instead of directly on it. This is why distant objects appear blurred.

4. **Evaluating the Options**:
- Option A: "Do not enter the eye at all" – This is incorrect as light does enter the eye.
- Option B: "Come to a focus at back of retina" – This is incorrect because in myopia, the focus is in front of the retina.
- Option C: "Come to a focus in front of the retina" – This is correct as it accurately describes the condition of myopia.
- Option D: "Come to a focus in between retina and iris" – This is also incorrect as it does not accurately describe the focusing issue in myopia.

5. **Conclusion**: The correct answer is that in myopia, the rays of light come to a focus in front of the retina.

**Final Answer**: The rays of light in myopia come to a focus in front of the retina.
