The blood supply of eyeball is mainly depending on a very thin central retinal artery and circulates back to the small vein, both of them are located in the center of the ocular nerve cord at the back of the eyeball, which is rather similar to a cherry fruit attached to a tiny stalk. It is an unreasonable design for our eye nutritional supply. The very thin central retinal artery with the diameter less than 1/5 mm is too heavy a burden to transport oxygen and nutrients to keep a well maintenance of the delicate retina, especially in the computer era with excessive radiation damage of the eyes. When the aged process goes on and the malnutrition status happens, such that high fatty food diet and wastes deposition onto the capillaries, that may cause blood vessels having micro-capillary clots forming, which is a subclinical blockage or narrowing of the diameter of those small arteries, veins and capillaries, that are rather difficult to detect. Although the currently clinical methods for curing glaucoma using eye drops and surgery to reduce the intra ocular pressure are in practice, it might be even more important to concern how to improve a good microcirculation of eyes. Many traditional Chinese herb medicines had practiced through thousand years and verified to have good effects on blood circulation and they are beneficial to eye-health. Small amount of alcohol, but not over dose, may help blood vessel relaxation. Hop in beer is a good antioxidant, which eyes are welcome. This is a try to formulate a DIY 15-herb extract enhanced beer to see if that drink could become an extra helper in healthy eye maintenance or to reduce glaucoma, AMD progress.
