What is the significance of the near point of eye in determining the optimal distance for reading and other close-up activities?

Answer 1

The near point of the eye is the closest distance at which an object can be seen clearly. It is significant in determining the optimal distance for reading and other close-up activities because it helps to identify the point at which the eye can focus most comfortably and efficiently. This distance is important for preventing eye strain and maintaining clear vision during tasks that require close focus, such as reading or using electronic devices.
