errrmm, I think pretty much all eyes have lenses.

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

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"?

is that its brain you can see then?

Technically eyes are part of the brain ontogenetically - so look into somebody's eyes and you're looking at their brain.
