The human retina, a thin membrane in the back of the eyeball upon which light is focused, is a miracle of bio-engineering. It’s about the size of a postage stamp, made up of a million cells that convert light energy into a chemical reaction and then into an electrical nerve signal, which is then sent to the brain. Technically, the retina is part of the brain and made up partially of brain cells, as well as two other types of cells called rods and cones, that differentiate light frequencies so that various colors can be perceived.
As it does with the rest of the body, aging takes its toll on the retina too, leading to damage and deterioration that is associated with various eye issues, including retinitis, pigmentosa and macular degeneration, as well as retinal detachments and tears.
Recently researchers have found that the culinary spice saffron may support retinal health. Saffron extract have been shown to raise antioxidant and glutathione levels within the eye. In addition to supporting the health of the retina, saffron can be protective against glaucoma and may help reduce the formation of floaters. You can find saffron capsules on the internet and in health food stores. It’s non-toxic. Start off with 100 to 200 milligrams a day, but it has no side effects and you can take as much as you want.
