I wonder what functionality eyes serve at that depth, and if none, why do the fish that live at these depths have them?

  It's likely that these species evolved from others that were closer to the surface. You also see that from species that live deep in caverns. They often have non-functional eyes, remnants from the time when their ancestors were living outside.

  Detecting bioluminescence.

    If that's the case, the camera light must have blinded them permanently.

People with experience or degrees in the subject seem to be widely admitting this is the case, but it applies to such a small percent of the deep sea that it isn't a major concern to them yet.

  That reminds me of something I didn't really like about the otherwise excellent Europa Report. <rot13> Jul jbhyq gur Rhebcn perngherf unir ribyirq ovbyhzvarfprapr, naq rfcrpvnyyl gur novyvgl gb hfr vg sbe pbzzhavpngvba, tvira gurve raivebazrag?
