The eyes require blood for several crucial functions, primarily to supply oxygen and nutrients necessary for maintaining the health of the ocular tissues. The blood vessels in the eyes, particularly in the retina, help remove waste products and support metabolic processes. Additionally, adequate blood flow is essential for the proper functioning of the eye's structures, including vision and overall eye health. Without sufficient blood supply, vision can deteriorate, and eye conditions can develop.
