Dr. Fred Pescatore has always called the nutrients lutein and zeaxanthin a “vision dream team.” And with good reason…
These nutrients shield and nourish your macula and slash your risk of developing vision-stealing macular degeneration by an astounding 82 percent.
They also shield the macula from one of the prime eye-attacking villains of modern life: Blue light. You’re constantly bombarded with this kind of light from your smartphone, tablet, computer screen, TV, and even LED lights.
And as Dr. Pescatore explains in his Ageless Vision Protocol, “With enough exposure, blue light can actively fade your vision and kill off eye cells. But optimal amounts of lutein and zeaxanthin help build a trusty barrier to block this harmful light.”
A study in the journal Foods shows just how powerful lutein and zeaxanthin are in stopping blue light from hurting your eyesight…
In the six-month study, researchers gave either a lutein/zeaxanthin combination or a placebo to 48 healthy adults who spent a minimum of six hours a day in front of a computer screen.
At the beginning and at the end of the study, researchers evaluated the volunteers for a range of visual effects—such as contrast sensitivity, glare, the ability to recover from visual stress, eye strain, and eye fatigue.
The researchers also measured participants’ macular pigment optical density (MPOD)—which is the amount of sight-saving macular pigments in the macula.
The results were remarkable across the board.
Those taking lutein and zeaxanthin had much higher MPOD and showed improvements in nearly every visual category. But as Dr. Pescatore notes, the improvement in contrast sensitivity might be the most impressive result.
The lead author of the study explains why, saying, “Contrast sensitivity is the ability to discriminate different shades of dark and light—and it’s probably the best real-world measure of visual performance there is.”
But lutein and zeaxanthin don’t stop there. Research also shows they prevent another leading cause of vision loss: Cataracts.
Cataracts occur when protein builds up in the lens of the eye, creating cloudy vision. Cataracts block the vision of 40 percent of people 75 and older—so taking preventive measures against it is key.
In the major Beaver Dam Eye Study, researchers found that high intakes of lutein and zeaxanthin were associated with a significantly lower risk of developing new cataracts compared to those who had the lowest intakes. And in a separate study, participants who consumed high amounts of foods with lutein and zeaxanthin had a lower risk for cataract surgery.
Clearly research confirms that zeaxanthin and lutein are essential for strong, healthy vision. So how much do you need?
Dr. Pescatore recommends supplementing with 4 mg of zeaxanthin along with 20 mg of lutein—both twice daily.
And it’s also important to get a few daily servings of zeaxanthin-rich foods, including dark green vegetables (like kale, spinach, collard greens, and broccoli, to name a few) and eggs (the yolk is loaded with zeaxanthin).
Of course, these aren’t the only nutrients that help keep your vision crystal clear. You can find other important recommendations from Dr. Pescatore in his Ageless Vision Protocol. Click here to learn more about his comprehensive plan for lifelong vision health, or to get started right away.
