To solve the question regarding the least distance of distinct vision for a normal eye, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Concept**: The least distance of distinct vision refers to the closest distance at which the eye can focus on an object clearly. If an object is closer than this distance, the image formed on the retina will be blurred. 2. **Identifying the Components**: In the human eye, light enters through the lens and is focused onto the retina. If an object is too close, the eye cannot adjust its lens to focus the image clearly. ...
