: What does the third eye add to the pfhor vison. The second eye on humans is
: for depth. So a third would be overkill in frontal vison. The seven eyes
: on the enforcers could see all around except for behind.
: Could the pfhor have poor vison? does a third eye impove this poor vison?
: And what about a tick?
Maybe the third eye sees different wavelengths?
Then it would probably look different from the other two, though.
Of course, there are lots of animals on Earth with more than 2 eyes, but I don't thnik any natural animal has an odd number.
