The red milkweed beetle (tetraopes tetropthalmus) has some interesting spacing between its sets of eyes. Their antennae basically bisects the two sets. Things like this always lead one to wonder what sort of field of vision they might have. When it comes to any many-eyed creature, I've long considered that their eyes produce a unified visual field, complete with appropriate blind spots. Rather than seeing four distinct images - which isn't cognitively efficient and must almost certainly prove a hindrance to survival - I suspect it's one. With a set of eyes almost literally on the back of its head, it's no surprise to find this beetle wildly sensitive to potential threats, quick to take cover.
