Question

Define the near point and far point of a normal eye

Answer 1

The minimum distance, at which objects can be seen most distinctly without strain, is called
the least distance of distinct vision. It is also called the near point of the eye. For a young adult with
normal vision, the near point is about 25 cm.
The farthest point up to which the eye can see objects clearly is called the far point of the eye. It is
infinity for a normal eye. A normal eye can see objects clearly that are between 25 cm and infinity.
