Does that xenomorph have an eye?

Peekaboo! :-)

Doesn't look much like an eye.

S.M but it does look like something we haven't noticed/seen before on a xenomorph.

Looks like the thin ribbed tube that runs along the base of the dome on the original creature.

 S.M that's kind of stretching it, it looks a little bit like that but not a lot

I think it being an eye is stretching things a bit further.

The eye isn't necessarily stretching it because xenomorphs are predatory and predatory species typically have eyes in the front (like us) and if it were a ribbed tube like you say it would hinder the ability to curl it's upper lip as shown and the eye is reminiscent of a fish's eye being pure black and rather small and besides when has a xenomorphs ever had one of those tubes so close to it's upper lip before?
