The eyes, as all the body’s organs, depend on the flow of oxygen-rich blood to function.
They have nerves and tissues that send signals to the brain to create a visual image.
One of these critical tissues is the retina, which is at the back of the eye.
The retina plays a crucial role in sending visual signals to the brain, and it contains small and large arteries and veins that move blood to and from the heart.
This blood is essential to vision, and a blockage in the retina’s blood vessels can permanently affect vision and lead to blindness.
