Natural Pigment May Be Key to Low-Light Vision
Back in junior high school, your biology teacher may have used a camera to explain how your eye works. It’s a fair comparison, but it leaves the impression your eye is a lot simpler than it really is.
In reality, your eyes make even the fanciest digital cameras look like something out of the Stone Age. Your eyes are far more sensitive to light than any camera. But time and use can dull your vision – especially at night.
Today I’ll reveal a secret to help promote healthy vision in dim light.
The back of your eye is lined with tiny photoreceptor cells. You have two kinds of these cells. Most of them are called cones, and they help you see detail and color. They outnumber the other cells – called rods – by about 9 to 1.
Even though your eyes don’t have so many rods, they have a critical job. They can’t distinguish color… and they don’t pick up as much detail as cones… but they’re far more sensitive to light. Cones give you “night vision.”
Cones depend on a special pigment, called rhodopsin, to function. When light – even dim light – falls on your rods, the rhodopsin changes chemically. This change creates an electrical impulse. The impulse travels to your brain. All these little impulses create the image of what you see in your brain.
In order to see, your body has to constantly regenerate rhodopsin. Otherwise, the messages to your brain from the rods would stop.
As you age, your body’s ability to regenerate rhodopsin begins to slow. This is a key reason most of us notice our night vision dropping off as we get older.
So, having a healthy supply of rhodopsin should make a big difference. And thanks to Mother Nature, you may be able to keep your supply healthy a lot longer.
The secret is a plant pigment with a fancy name: cyanidin 3-glycosides. Or C3G, for short.
Test tube studies on C3G show it stimulates regeneration of rhodopsin. A 2003 Japanese study showed C3G sped up the regeneration process in cell samples taken from frogs.1
Researchers from the University of Pittsburgh confirmed these results.2
Of course, test tubes are one thing. If your body can’t absorb and distribute C3G where it’s needed, it won’t do you much good.
Fortunately, this has already been proven in both animals and humans.
Research shows your body is able to absorb C3G well… and that it circulates normally in your blood. Which means it can get to where you need it.3
Dark purple berries are the richest food sources of C3G. But only some. Blueberries, for example have a little – but only about 12 micrograms per gram of fruit. That’s about 340 micrograms per ounce.
Black currants, on the other hand, deliver more than 30 times that amount per ounce. Bilberries contain even more C3G than that… up to 46 times more than blueberries.
You usually can’t find bilberries in your local supermarket. But you will find bilberry concentrate in some nutritional supplements. It’s the easiest way to take advantage of the benefits of C3G.
Yours in continued good health,
