How exactly do you apply the Garnier Eye Roll-On? - garnier eye

I bought this to get rid of dark circles and I'm not sure if I use it. Can I use directly on the skin under the eyes or skin, should I apply a little deeper, like the photo that appears in your package. plz help me out here. Thank you!

I use a little paranoid, as I believe, can lead to blindness. so plz help me in this area.
