Myopia (near-sightedness) is a defect in human eye in which the image is formed

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Myopia**: Myopia, also known as near-sightedness, is a common vision condition where a person can see nearby objects clearly, but distant objects appear blurry.

2. **Image Formation in Myopia**: In myopia, the image of a distant object is formed in front of the retina instead of directly on it. This occurs because the eyeball is either too long or the cornea has too much curvature.

3. **Comparison with Hypermetropia**: To differentiate myopia from hypermetropia (far-sightedness), it is important to note that in hypermetropia, the image is formed behind the retina. This helps clarify the specific nature of myopia.

4. **Correction of Myopia**: Myopia can be corrected using concave lenses. Concave lenses help diverge light rays before they enter the eye, allowing the image to be focused correctly on the retina.

5. **Choosing the Correct Option**: Given the options:
- A) In front of retina and can be corrected by using concave lens
- B) In front of retina and corrected by using convex lens
- C) Behind the retina corrected by using concave lens
- D) Behind the retina and corrected by using convex lens

The correct answer is option A: "In front of retina and can be corrected by using concave lens."

**Final Answer**: Myopia (near-sightedness) is a defect in the human eye in which the image is formed in front of the retina and can be corrected by using a concave lens.
