How does poor circulation affect the eyes?
Like a stroke in the brain, this happens when blood flow is blocked in the retina, a thin layer of tissue in the eye that helps you see. It can cause blurry vision and even blindness. Arteries carry blood to the retina from the heart. Without blood flow, the cells in the retina don’t get enough oxygen.
Can lack of blood flow cause blurry vision?
If blood supply within the eye is limited, vision may appear blurry or out of focus. Blurriness most often affects central vision, which can also result in a limited field of vision.
Can blocked arteries affect your eyes?
