So without the helmet, zerogokis face looks like this:
".O"

Wouldn't that result in an imbalanced vision, causing imprecise target which isn't the case as we see it hurl the spear javelin style, hitting Arael flawlessly. Now it can be said that Rei perfected the target alongside the help of on-board computer. But during the activation test, in bersek state, it punched the glass pane right in front of Gendo and Ritsuko in purpose of hitting them both. If it had imbalanced vision, it would've hit the wall beside them since it sees from its eye(s) and Rei had no control over it. My guess is odd number of eyes, like 1 giant one or 3,5,7. Something like that. I mean it's possible since unit 2, 8, 13 has more than 2 eyes. Since 00 was the first and the prototype one, maybe they thought of making multiple eye holed face shield would be weird from appearance. So they simply made a giant one, from which every one of those eyes can see through. Just my speculation.

What I had in mind was more that the second eye would be tiny & basically useless/ not see anything at all, or maybe just distinguish light & dark like primitive worm eyes.
So they sort of left it in but didn't build a window for it into the armor

a) They just copied a list of organs from somewhere and didn't screen it further, ie, this is unintentional. Then again, while you could imagine a bunch of animators not knowing about obscure glands, you'd think they would have caught the eyes.

I also believe in that one. That one image is all that ever comes up in the show on this whole mess, and too much of it has to be explained away with ridiculous and unlikely contraptions, or just doesn't make sense at all. Far more likely than not, it was a simple production oversight, like when the MPs in EoE suddenly come from a completely different direction than last seen.
As much thought went into Eva, creative stuff is not immune to human error, and this is almost definitely a case like that.

According to the Eva 00 Soul of Chogokin figure, it doesn't have any eyes at all.
