For the myopia defect in eye, it can be removed by

Options

A. convex lens
B. concave lens
C. cylindrical lens
D. toric lens

Explanation

**Step-by-Step Solution:**

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

2. **Image Formation in Myopia**: In a person with myopia, the image of a distant object is formed in front of the retina instead of directly on it. This is the reason why far objects appear blurred.

3. **Correcting Myopia**: To correct myopia, we need to adjust the focal point of the light rays so that they converge on the retina. This can be achieved by using a lens that diverges the light rays before they enter the eye.

4. **Choosing the Right Lens**: The appropriate lens to correct myopia is a concave lens (also known as a diverging lens). A concave lens causes the light rays to diverge, which effectively moves the focal point further back, allowing the image to be formed on the retina.

5. **Conclusion**: Therefore, the correct answer to the question is that myopia can be removed by using a concave lens.

**Final Answer**: Myopia defect in the eye can be removed by using a concave lens.
