It’s an sf movie about aliens made of light or sth like that. One of them (a princess?) was sent to Earth and disguised as a little girl who grows up not knowing she is an alien. She finds out when enemy alien race comes for her. There is also her friend who helps her and an old lady/ladies from the neighbourhood who are also aliens and are on the mission to protect the girl. I remember a scene where that friend (a boy) is given glasses which enable him to see those aliens in their original form because they are made of some sort of energy and hard to look at without them.
