The vision range for a normal human eye is:

Options

A. 25 cm to infinity
B. 25 cm from zero
C. 60 сm from infinite
D. 50 cm from infinite

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Vision Range**: The vision range of a normal human eye refers to the distances at which a person can clearly see objects without any corrective lenses.

2. **Identifying the Near Point**: The near point is the closest distance at which the eye can focus on an object. For a normal human eye, this distance is approximately 25 cm.

3. **Identifying the Far Point**: The far point is the farthest distance at which the eye can see an object clearly. For a normal human eye, this distance is considered to be infinity.

4. **Combining the Near and Far Points**: Therefore, the vision range for a normal human eye extends from the near point (25 cm) to the far point (infinity).

5. **Conclusion**: Thus, the vision range for a normal human eye is from 25 cm to infinity.

**Final Answer**: The vision range for a normal human eye is 25 cm to infinity.
