The far point of a myopic person is 80 cm in front of the eye. What is the nature and power of the lens required to correct the problem?

Explanation

To solve the problem of determining the nature and power of the lens required to correct the vision of a myopic person whose far point is 80 cm, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Myopia**: Myopia, or nearsightedness, is a condition where a person can see nearby objects clearly, but distant objects appear blurry. The far point of a myopic person is the maximum distance at which they can see clearly. In this case, the far point is given as 80 cm.

2. **Identify the Image Distance (v)**: For a myopic person, the far point is the image distance. Since the image is formed in front of the eye, we take this distance as negative. Therefore, \( v = -80 \) cm.
