The brain consumes 40% of the oxygen in your blood.

The cornea is the only organ in the human body that does not have a direct blood supply. It receives nutrients and oxygen from tears and the aqueous humor that surrounds it.
The organ that supplies a human's bloodstream with oxygen from the air is the lungs. When we inhale, air enters the lungs, and oxygen from the air diffuses into the bloodstream through the alveoli, tiny air sacs where gas exchange occurs. This oxygen-rich blood is then circulated throughout the body to supply tissues and organs.
The human organ system that circulates blood is called the circulatory system or the cardiovascular system. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. This system transports oxygen, nutrients, hormones, and other substances throughout the body, as well as removes waste products.

The heart is responsible for supply of food and oxygen to all the cells in your body. The function is done through blood supply.
The cornea in the eye does not receive oxygen from blood. Instead, it gets its oxygen directly from the air.
