The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Vision Disorder**: The question refers to a vision disorder associated with old age, which is commonly known as hypermetropia or farsightedness. 2. **Understanding Hypermetropia**: In hypermetropia, individuals can see distant objects clearly, but nearby objects appear blurry. This condition occurs because the eye's shape causes light rays to focus behind the retina instead of directly on it. 3. **Image Formation**: In hypermetropia, the image of nearby objects is formed behind the retina. This is the key point to answer the question. 4. **Correction of the Disorder**: To correct hypermetropia, a convex lens is used. The convex lens helps to converge the light rays before they enter the eye, allowing the image to be focused directly on the retina. 5. **Conclusion**: Therefore, the correct answer to the question is that in hypermetropia, the image is formed behind the retina, and it can be corrected with a convex lens. **Final Answer**: The image is formed behind the retina. ---
