I see it differently:
Also people with one eye can see perspective.
Perspective has to do with relative distance to the subject.
At the right distance for a certain perspective, you have to chose a angle of view for the wanted size of he subject.

Well, it depends on how the eyes of those aliens are lined up.

The "normal" lens is "normal" for a human. (Just to remind in case someone here has forgotten: the normal lens provides the perspective close to that seen by a person.)

So, for an alien with two eyes located closer to each other then ours or even vertically, it will be all very different.

BTW, while my daughter was very little, just a few months old, some of the photos of her that I took were with Sigma 24/1.8 purchased from one of the
PDMLers. I needed a fast lens and I needed to shoot from a short distance
(usually I needed to be able to catch her or reach her with my hand.
So, some of the facial views were a bit "alien-like".


As for the original plastic surgeon, - I'd like to get his opinion on this photo:

and this:

Cheers!

Yep. I've been saying for ages that aliens examining our culture will
get a very distorted impression of what our faces looked like based on
modern smartphone selfies.
