**Subtype:** Lens and Eye Function  
**Problem Description:** This problem involves understanding how the focal length of the eye's lens and the angle of view change as an object moves closer to the eye. Specifically, it asks about the relationship between the focal length of the lens and the angle of view when an object is moved from a distance to the near point of vision.  

**Key Concepts:**  
- **Focal Length:** The distance from the lens to the point where light rays converge. In the context of the eye, this refers to how the eye's lens adjusts to focus on objects at different distances.  
- **Angle of View:** The angle at which an object can be seen by the eye, which changes as the object moves closer or further away.  

**Question:** As the object moves closer to the eye, how do the focal length and angle of view change?  
- A. Focal length increases, angle of view increases.  
- B. Focal length increases, angle of view increases.  
- C. Focal length decreases, angle of view decreases.  
- D. Focal length decreases, angle of view increases.  

This problem tests the understanding of how the eye accommodates to focus on nearby objects.
