How does our near point affect what we do and see?
The near point is the shortest distance that can be seen
clearly by human eye and at the near point an object will form a
sharp image on the retina (accurately focused).
For a normal eye, nearest point is usually located at a
distance of 25cm from the eye.
If the near point distance is shorter, the eye has a greater
ability to accomodate for changes in distance. The near point
distance increases as one ages causing farsighted condition. This
condition is called Presbyopia. People who suffer from Myopia, the
distance of near point is less.
