This is still the problem. Remove those quotes. And you could remove the brackets as well, they aren't necessary.
Indeed. And while pidof would have probably been a better solution for the initial problem we thought we were trying to solve, I think knowing that you only want to skip user1 from starting new xeyes if it is already running for user1 that pgrep will be better suited. With pgrep you can use the -u/--euid or -U/--uid option to limit the match to xeyes processes which are running for the proper user.
Something like:
if ! pgrep -u user1 xeyes > /dev/null; then xeyes ... fi
