When someone sees the inner beauty of everyone
because they know physical appearance can't be helped, but personality can. Due to this, they "see" people for who they really are. A beautiful person can remain beautiful looking to them, however if their personality is ugly, the person with Shallow Hal Goggles
will not be interested.
Comes from the movie Shallow Hal, in which Hal is hypnotized to see people for who they are on the inside.
