we've seen ship battles in unusually close (and probably unrealistic) quarters.
Made me crazy in modern Trek. One can excuse it in TWOK as Khan was aiming to get as close to Kirk as possible, and then they had to be damn close in the nebula to see each other at all.
But in modern Trek, ships are right on top of each other.
TOS was much more realistic in that regard. When ships are firing at each other from kilometers away from each other, they can't see each other with the naked eye.
