I would bet if you shine enough light on it, or get the flash right on the face, the eye will show the eye stripe behind it.
In any case the eye not showing the eye stripe doesn't mean anything, just that the eye is dark compared to some.
The photo I showed up there is a dark eye without flash that snake looks like it has black eyes.
So would you say this snake is a dark normal with a busy belly or possible sable? It looked much darker than any normal the breeder had and more like one of her sables.
I say it could be a sable. The eye stripe has nothing to do with it though. Look more at the pattern and speckling inside the alien heads. Here is a pic of mine as a baby for comparison.
and her as a big girl
