Hypermetropia (long sight) is a condition in human eye in which the image is formed

Options

A. Behind retina and can be corrected by using a concave lens
B. Behind retina and can be corrected by using a convex lens
C. In front of retina and can be corrected by using a concave lens
D. In front of retina and can be corrected by using a convex lens

Answer

**Step-by-Step Solution:**

1. **Understanding Hypermetropia**: Hypermetropia, commonly known as long-sightedness, is a condition of the eye where distant objects can be seen clearly, but nearby objects appear blurry. This is due to the light entering the eye being focused behind the retina.

2. **Image Formation**: In a normal eye, light rays converge at the retina, allowing for clear vision. However, in hypermetropia, the focal point of the light rays is located behind the retina. This misalignment causes difficulty in focusing on close objects.

3. **Comparison with Myopia**: It is essential to differentiate hypermetropia from myopia (short-sightedness), where the image is formed in front of the retina. Myopia allows for clear vision of nearby objects but blurs distant objects.

4. **Correction of Hypermetropia**: Hypermetropia can be corrected using convex lenses. These lenses help to converge the light rays before they enter the eye, allowing them to focus correctly on the retina.

5. **Final Answer**: Based on the understanding of hypermetropia, the correct statement is that hypermetropia is a condition in which the image is formed behind the retina and can be corrected using a convex lens.

**Conclusion**: The correct answer is option B: "Hypermetropia is a condition in human eye in which the image is formed behind the retina and can be corrected using convex lens."
