Their eye coloration is pretty cool. It throws me off when looking at the photos in Lightroom because its diffuseness looks like it's out of focus but that's just how they are. I wonder if there's any functionality to it with eyesight, like are the lighter areas better for low-light vision?
Not sure. It looks like they have compound eyes like other insects but you may well be right it may be a special adaptation for certain conditions. The other thing is it could be some kind of camouflage if predators use their eyes as a means to identify them. If you look at all the other butterflies they don't seem to have the colouration and their eyes look more plain so it must confer some kind of survival advantage in this case.
