please help!

im trying to code two responsive eyes - eyes follow mouse. But in a simple way.
My code is below. And only thing missing in it is that eyes dont follow mouse while it is in between them.
I also tried loops.. But not too much success whit it. Eyes are skipping. That code is also below.

Thank you!!!


int r1=100;

void setup ()
{
  background (255);
  size (800,400);
  smooth();
}

void draw ()

{
  int x = int (map(mouseX,0,width,-r1/8,r1/8));
int y = int (map(mouseY,0,height,-r1/8,r1/8));

int cx=width/2;
int cy=height/2;

eyeBall (cx-100, cy,cx-100+x, cy+y);
eyeBall (cx+100, cy,cx+100+x, cy+y);

}


void eyeBall (int x, int y, int xI, int yI)
{

fill(255);
ellipse (x, y, r1,r1);
fill(#CE5588);
ellipse (xI, yI, r1/2,r1/2);
fill(0);
ellipse (xI, yI, r1/20,r1/20);
}
