from which organism's eye has the human eye advanced from?
is the eye of other primates different from ours?

The eye has evolved about 40 different times. There are separate developments in different mammals - cats' eyes, for instance, are different from primates' eyes. Squid and octopus eyes are far more efficient than human eyes and evolved along a different path from ours. Structurally they are very different from ours.

Eyes go back a long way. They started out as a few light sensative cells on aquatic creatures a billion years ago. The human eye is not significantly different than most othe creatures for the last several hundred million years.

From the eyes of earlier primates, who's eyes were essentially the same as ours.
And so on back through the lineage of human ancestry.

The evolution of human eye parallels vertebrate evolution,although there is a remarkable constancy in its structure during the course of evolution of this remarkable bunch of photoreceptor.

Octopus eyes are VERY similar to mammals eyes but evolved completely separately.
