Solving Simple Vision Problems and More
Overlooked Vision Booster Delivers Major Benefits
Mainstream medicine tells you your vision naturally fades with age. They believe there’s nothing you can do to keep your vision clear and sharp well into your “golden years.” So they give you stronger and stronger glasses and tell you it’s just the way things are.
But science says it doesn’t have to be this way. Studies show an overlooked vision booster delivers major benefits. Benefits that could help keep your vision sharper for years to come.
This amazing nutrient fights vision damage in many ways. Plus, it’s common, inexpensive, and remarkably powerful.
Today, we’ll look at how to harness its power to promote clear, sharp vision well into the future.
Solving Simple Vision Problems and More
Having dry eyes seems like a minor problem. But this “nuisance” doesn’t feel so minor after a few years of frustration.
So a simple, safe, and natural solution to dry eyes is no small feat.
And that’s exactly what you could get with quercetin. This simple compound defends plants from damage, but it can defend your eyes as well.
In fact, a 2014 study shows just ½ of 1% of quercetin in the diet may be enough to ease dry eye problems.1
Quercetin – also called Q – fights tougher problems, too. For example, Q defends against vision loss 4 ways:
1. It’s a potent antioxidant
2. Q promotes nerve health
3. It discourages growth of unhealthy cells
4. As a natural part of your diet, your body tolerates Q well
Studies suggest Q may be effective against the most common cause of age-related vision loss.2
Q helps defend some of your eyes’ most delicate cells from damage. The Retinal Pigment Epithelium (RPE) is a layer of cells that nourishes the light-sensitive rod and cone cells in your eye. Q helps these key cells defend against damage from:
• Common forms of systemic irritation3
• Free radicals that break down cell walls4
• Certain attacks from your body’s own immune system.5
Q defends your eyes in other ways, too.
Vision Defense Against High Cholesterol and UV Damage
High cholesterol is one of today’s most common threats to heart health. But it’s also a threat to your vision.
High cholesterol can lead to plaques that break off from arterial blockages and wind up in your eyes. These floating plaques can get stuck in the tiny arteries in your eyes, causing a blockage.
Blockages stop the blood flow that feeds cells in the eye, leading to cell death and vision loss.6
A 2000 study published in Clinical Chemistry looked at the effect of Q on cholesterol oxidation. Levels of oxidized cholesterol dropped in volunteers who took Q. This is key, because it’s oxidized cholesterol that forms blockages in your blood vessels.7
Other studies point to Q defending against damage from ultraviolet (UV) rays.
The visible spectrum – the light we can see – is just a tiny slice of the radiation the sun emits. We can’t see them, but infrared and UV light also flood in when we open our eyes. And UV triggers free radicals that attack your eyes’ delicate tissues.
Animal studies show Q cuts down on this UV damage. Lower levels of damage also led to fewer cells going through “programmed cell death.”8 This process is your cells’ way of preventing cell division if its DNA has been damaged.
As you can see, quercetin is a powerful ally for healthy vision. But we haven’t covered all its benefits…yet.
Even More Ways Q Supports Eye Health
Clouding is one of the most common vision problems for aging eyes. Every year, their view of the world begins to fade for tens of thousands of mature adults. But Q can help block this problem.
A few years ago, doctors in Britain created a model of lens clouding using lens cells. They exposed the cells to hydrogen peroxide (H2O2), which causes free radical damage. This damage makes lens cells go cloudy.
This model showed Q can block the destructive activity of H2O2, and slow lens clouding.9
Another common vision problem may occur when your blood sugar is out of control.
High blood sugar levels can damage the tiny blood vessels that feed your eyes. This eventually leads to vision loss as cells in your eyes begin to literally starve and die off.
Scientists in India and the U.S. triggered a loss of blood sugar control in a group of animals. They gave Q to some of their subjects, but not to others.
Over 6 months, the subjects that didn’t take Q showed increased levels of compounds linked to nerve damage in the eyes. Levels of these compounds were lower in the group taking Q. The non-Q group also experienced higher rates of nerve cell death in the retina.
The study’s authors concluded Q defended the treated group against eye damage caused by out-of-control blood sugar.10
Q also appears to discourage pressure damage to nerve cells in the retina.
Your eyes are filled with fluid that flows in and out at a steady rate. As long as the process works smoothly, your eyes have a steady pressure level. But if the outflow slows, pressure can build up, leading to severe damage.
A team at Vanderbilt University Medical Center tested the effect of Q on a model of this “intraocular pressure.”
At normal pressure levels, Q had no effect on the survival rate of retinal nerve cells. But when the pressure increased, moderate doses of Q boosted the cells’ survival rate.
In this model, very high Q levels did more harm than good. But modest doses defended the nerve cells against the damage normally caused by increased pressure.11
So Where Do You Find Quercetin?
Yellow onions are a good source of quercetin. Berries, cocoa, apples, red wine, spinach, celery, and several other fruits and vegetables have varying amounts. So, if you eat plenty of these foods, you probably get a decent amount in your diet.
But if you’re not good about getting your “five a day” servings or you don’t eat a good mix of these foods, you can get quercetin in supplement form.
Of course, if you’re concerned about your vision, quercetin isn’t the only nutrient you should consider. The so-called AREDS formula – made up of antioxidant vitamins and zinc – is also key. Along with lutein, zeaxanthin, and a number of other eye nutrients.
But you could go a little crazy taking so many supplements. That’s why a complete vision formula makes sense. And why you may want to check out Visanol – the most complete vision formula I’ve seen.
