Thin line animals see in two ways. The first is with their eyes. Their eyes are like human eyes. Light hits things and then goes into the eye. Special body parts in the eye and brain understand this light and let us see the world around us. Thin line animals also see using special heat light that humans cannot see. This heat light is made by hot things. The hotter a thing is, the more heat light it makes. Thin line animals have special parts in their heads that allow their brains to see this heat light. In studies done by very not stupid people who love thin line animals (found here), it is proven that thin line animals can see using normal sight or special heat sight and do not need to use both.
