There's a movie called Invaders From Mars that shows this, which is also similar to the Invasion of the Body Snatchers and a bunch of others like that.
In this, they go in through the back of the neck instead of the eye.
In this remake of the classic 50s SF tale, a boy tries to stop an invasion of his town by aliens who take over the the minds of his parents, his least-liked schoolteacher and other townspeople. With the aid of the school nurse the boy enlists the aid of the U.S. Marines.
