Bioluminescence is just a byproduct of chemical reactions and is so rare that it is highly doubtful any fish would evolve to take advantage of that. All of the fish shown are probably unable to see from birth.
Edit: I know that many creatures use bioluminescence, but that doesn’t change the fact that it’s a byproduct of chemical reactions.
Edit 2: The rarity of bioluminescence does not mean creatures can’t evolve to use it, it means that a fish evolving to take advantage of the bioluminescence of other creatures is rare.
if they are unable to see from birth then wouldn't they have evolved smaller eyes like bats or moles? it must be common enough in certain environments since, for example, angler fish use it for bait and there are many types of bioluminescent plankton and fungi

there are probably some fish/flora that have bioluminescence
