The eyes and lens

The vision is adaptive.

About the human eye you have the point next that is 15cm of the eyes in the perfect vision, and the distant point is the infinite, but when the person are miope the near point gonna be more and more near the eyes so the person has to see the objects near of the eyes and the distant point came near the person depend how bad is the miopia.

And the eye get adapted to the luminosity, to high and low luminosity closing the iris whe the luminosity is high and opening when the luminosity is low, so is that why the oculist put eyedrop to dilate the iris to they don't adapt and the lens be perfect for the eyes of the person, with the age the person will lose the adaptivity, why the camera is diferent.
