Question

What is the near point focusing?

Short/Brief Note
Advertisements

Solution

The image is formed at a near point, i.e. 25 cm for the normal eye. This distance is also called as least distance D of distinct vision. In this position, the eye feels comfortable but there is little strain on the eye.
