Perhaps you are unaware of the history of this forum. 🙂

There has been quite a bit of discussion on this topic, just not much recently. I think this is the oldest one:

> The first step is in realizing that all of these features you list aren’t needed for a functioning eye, and there are species with eyes that lack many of these features. A great example are the Planarians, a group of flatworms: [image] All they have is an eye cup. It is a pit with light sensitive cells at the bottom. The indentation allows for very crude directionality, but it doesn’t form a focused image and it certainly doesn’t have bones, ducts, and the other stuff you are talking about.

with addition side discussion:

And a bit here:

BUT maybe I misunderstand what you are asking?  
If one step is all you need, I do not understand why you think all the steps must be difficult.
