Transcript: Prevent Glaucoma and See 27 Miles Farther
Glaucoma is a deterioration of your optic nerve, the nerve that connects your eyes to your brain, and is second only to cataracts as the world’s leading cause of blindness. The weird thing is that we still don’t know what causes it, and so there’s a desperate search for environmental or dietary influences.
The most protective dietary component, decreasing the odds of glaucoma by 69%: consuming at least one serving a month of collard greens or kale. Just once a month or more. And the silver and bronze metal goes to weekly carrot and then peach consumption.
We think it may be the lutein and zeaxanthin, two yellow plant pigments, that seem to know right where to go, they hone right in to our retinas and appear to protect against degenerative eye disease.
They allow us to see farther too. Their peak light absorbance just so happens to be just the wavelength of color of our planet’s sky, and so by filtering out that blue haze, on a clear day standing on top of a mountain individuals with high macular pigment—lutein and zeaxanthin— would be able to distinguish distant mountain ridges up to 27 miles further than individuals with little or no pigment.
