Defects of vision such as myopia and hypermetropia are corrected by the use of appropriate optical lenses. Find out more about these corrective lenses

Explanation

### Step-by-Step Solution:

1. **Understanding Myopia**:
- Myopia, also known as nearsightedness, is a condition where a person can see nearby objects clearly, but distant objects appear blurry. This occurs because the eye's focal length is too short, causing light rays to converge before they reach the retina.

2. **Corrective Lens for Myopia**:
- To correct myopia, we need to reduce the eye's converging power. This is achieved by using a **concave lens** (diverging lens). The concave lens helps to spread out the light rays before they enter the eye, allowing them to focus correctly on the retina.
