When does an object become visible to us?
Answers
Things become visible to the human eye when light bounces of it. The light is the first step to make the illuminated object visible. However, that is not all that it takes there are still more to it. First light bounce off the object, then the object reflects one color of the light and it hits your eye. First, the light travels past your cornea, then to the aqueous humor, next, to the iris, then finally to the pupil, where light is going into the internal eye.
In the internal eye, the light go past the vitreous humor, next to the retina. Then the most important spot the blind spot, the entrance to the optic nerve, so you could define what the object is. The optic nerve leads to the brain, where objects are define. Therefore, that is how light and objects can be seen.
In short: Things become visible to the human eye when light bounces of it.
