Why are magic eyes such a popular troupe?
Magic eyes
Would you rather magic cock?
They LOOK cool, haha
As humans we express ourselves in a wide variety of ways with eyes alone. It's also normal to maintain eye contact during conversation.
Both of these answers combined give the truest answer to the question.
Makes sameface-designs easier to differentiate, also easy power-ups with minimal efforts. Also focuses the viewer to the intended specific spot for tension or emotion in general.
Cocks are pretty magic tho
It looks fucking cool.
Naruto did some of the coolest-looking eyes deSu. Can't think of one I disliked in that franchise (I watched up to the ninja war thing). Too bad it devolved so deep into O MY SPECIAL EYES wankery.
Unlike most other animals, we rely a lot on our eyes only. Giving them magic abilities just makes them seem even more powerful and mysterious.

It isn't in Japan though. Looking someone in the eyes is seen as an act of aggression there.
