He Needs Dark to See

Light bored 
into his eyes but where did it go? 
Into a sea of phosphenes,
along the wet fuse of some dead 
nerve, it hid everywhere and couldn't 
be found. I've used up
three guesses, all of them
right. It's like scuba diving, going down 
into the black cone-tip that dives 
farther than I can, though I dive 
closer all the time.
