Birds' Eyes

To my human senses, a male Satin Bowerbird has the most exquisitely
beautiful eyes of any birds I have seen.  Their lovely violet colour seems
a perfect accessory to his handsome plumage.

So I wonder if female SBBs also find the colour attractive, and that is why
it has evolved.  Or is there some other physiological explanation?

Can anyone comment?
