Changing the position of an object while its animated

I apologize if the title doesn't make sense I'll try to explain in the comments if something doesn't make sense. I'm new to after effects but l'm trying to make an opening movie. The beginning of this movie has eyes looking left and right while the background slowly pans downward. The problem I have is that I need the eyes to pan down with the background and look left and right at the same time. The way it is now is the eyes move left and right then start panning. Is there a way to make the eyes pan with the background without using the position (that's how they move left and right) Thanks for the help.
