Smart vision low light

Jensen pushed through the gap and found a ladder that
allowed him to descend quickly and quietly. Stacks followed,
grimly moving down one rung at a time, hand over hand.

There was little light, but his smart vision mode got past that problem,
the Eye-Know optics rendering the area in a grid of geometric shapes that
he could navigate easily. He glanced over his shoulder. “Still with me?”
“I gotta choice?” grumbled Stacks. He followed as Jensen moved on, but
he was flinching at every echo of noise from above them, every knock and
thud of the pipes that lined the sub-basement floor.
