Heh yeah, maybe I'm seeing this wrong. It looks like the lenses are surrounded by transparent stuff so what would be the point of focusing an image onto whatever it has in the way of light sensors if light can come in from any other direction.

the story said it lives 2000 feet below sea level in inky water, so think of it as night vision.

Yep, owls also have barrel shaped eyes for the same reason . . . well not the 2000ft bellow sea bit, but you know what I mean! :hehe:

No way!
Just an example:
The "pinhole camera" eye was developed as the pit deepened into a cup, then a chamber. By reducing the size of the opening, the organism achieved true imaging, allowing for fine directional sensing and even some shape-sensing. Eyes of this nature are currently found in the nautilus. Lacking a cornea or lens, they provide poor resolution and dim imaging, but are still, for the purpose of vision, a major improvement over the early eyepatches.

There is always one isn't there! And yes I know eyes evolved from photosensitive cells up to what is traditionally thought of as an eye, and that every stage of evolution still exists in nature.

Next time I'll be more specific. Smart arse :rofl:

There is a book turd, sorry I meant nerd, in every group some just hide it better than others, perhaps this is part II of "A Beautiful Mind"? :hehe:
