What is the far point and near point of the human eye with normal vision?
The farthest point of the human eye with normal vision is infinity.
The nearest point of the human eye with normal vision is 25cm.
At the farthest point, when we focussed at any distant object, beyond the 6m. eyes are said to be at rest because ciliary muscles are relaxed, lens get thin and refraction got decreased. And, at the nearest point, we can see the objects very clearly. Light rays from near objects in the range of 6m. are diverging when they strike the eye. High refraction value is needed for the nearest objects. To see the nearest object, eyes get contracted, lens gets thick and refraction got increased.
