In any case, if it's just to print the matchmatching file paths, you don't need ls. In zsh, you could use its print builtin to print in columns:
 If instead you want to check if there's at least one non-hidden file in any of those two directories, you can do:
# bash
if (shopt -s nullglob; set -- /some/path1/* /some/path2/*; (($#))); then
   echo yes
else
   echo no
fi
 Or using a function:
has_non_hidden_files() (
  shopt -s nullglob
  set -- "$1"/*
  (($#))
)
if has_non_hidden_files /some/path1 || has_non_hidden_files /some/path2
then
  echo yes
else
  echo no
fi
# zsh
if ()(($#)) /some/path1/*(N) /some/path2/*(N); then
  echo yes
else
  echo no
fi
 Or with a function:
has_non_hidden_files() ()(($#)) $1/*(NY1)
if has_non_hidden_files /some/path1 || has_non_hidden_files /some/path2
then
  echo yes
else
  echo no
fi
(Y1 as an optimisation to stop after finding the first file)
 Beware those has_non_hidden_files would (silently) return false for directories that are not readable by the user (whether they have files or not). In zsh, you could detect this kind of situation with its $ERRNO special variable.
