Is there an out-of-universe reason for the Gundam series mech head designs?


As I watch the shows I am constantly noticing the patterns in the head designs
of the mobile suits.

Any true Gundam, or otherwise important mech, will always have two eyes and
usually the V horns. Any generic suit, or one belonging to a more shallow
villain, will only have one eye.

Is this any kind of cultural reference?

EDIT

In Unicorn characters say that a mech becomes a Gundam when the horn opens
into a V. As if the V horns are something very specific.




[According to Kunio
Okawara](http://www.nationmultimedia.com/business/Simplicity-key-to-
successful-design-30259167.html), the mecha designer for the series:
