There aren’t any “next steps”. There is no goal, no destination.
There isn’t even a guarantee that human beings would evolve human like eyes if we wound the clack back and let it go again. We’d simply call whatever has happen “human like”, as we have.
If, by “human like” you mean eyes that interact with a central nervous system, we absolutely don’t expect a creature with eyes and no cns to evolve a cns on account of how it has eyes.
There’s no known step or process by which this would occur, things don’t evolve to “get” anything, or more of anything, this is simply not something that we observe happening.
