Clinical Studies: Silver Controls Bacteria and Other Microbes on Contact Lenses

By natural health author Tony Isaacs

Do you wear contact lenses?

If so, you’re in plenty of company. In fact, an estimated 46 million people in the United States wear contact lenses, according to the Center for Disease Control (CDC).

While contact lenses are wonderful tools for helping vision problems as well as cosmetic tools to use to avoid having to wear glasses and often to intensify or change perceived eye color, they have one very large downside: improper use may lead to serious eye infections because they can be breeding grounds for bacteria, fungi, and other microbes.

According to

“A new Morbidity and Mortality Weekly Report from the CDC shows that more than 80 percent of contact lens wearers reported at least one behavior that put them at risk for a contact lens-related eye infection.

The report broke down the rates by age groups, where 85 percent of adolescents (ages 12-17), 81 percent of young adults (ages 18-24), and 88 percent of older adults (ages 25 and older) practiced unsafe lens use.”

In other words, the CDC report demonstrates that more than 80% of contact lens wearers are at risk for eye infections. The CDC also states that “serious eye infections that can lead to blindness” affect up to one in every 500 contact lens users per year. Since about 46 million Americans wear contact lenses, that’s about 92 thousand serious eye infections a year.

What’s more, reports that “Nearly a million Americans visit the doctor each year for eye infections, which are often related to wearing contact lenses…”

Indeed, in one recent year, some 930,000 American contact lens wearers made doctor visits for eye infections, and 58,000 emergency room visits were made for microbial keratitis, the most common eye infection for contact lens wearers.

But what if I told you that both clinical evidence and anecdotal evidence demonstrate colloidal silver to be an effective disinfectant for contact lenses that can help keep your eyes infection-free?

Four Common Eye Infections
Caused by Bacteria and Other Microbes

Before we jump to the anecdotal and clinical evidence for the use of silver to reduce the risk of infection from contact lens use, let’s take a quick look at the four most common eye infections associated with contact lens usage:

1.) Conjunctivitis (a.k.a. Pink Eye) — Conjunctivitis is the term used to describe an inflammation or swelling of the conjunctiva, which is the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the so-called “whites of the eye” portion of the eye.

This infection is also commonly known as “pink eye”, and it can be either viral, bacterial, or it may develop due to an allergic reaction to irritants such as pollen, smoke, chlorine in swimming pools, synthetic cosmetics, or contact lenses.

Pink eye conditions are very commonly found among children and when caused by pathogens can be highly contagious. Pink eye can easily spread through hand-to-eye contact by hands that have been in contact with the infectious microbe. It’s believed that viral conjunctivitis might even be spread through sneezing and coughing.

Some of the symptoms are: Pink discoloration to the white in the eye(s), itching or burning sensation in the eye(s), excessive production of tears, swollen eyelids, increased light sensitivity, and, in more serious infections, discharge.

2.) Keratitis (a.k.a. Corneal Infection) — Keratitis is the medical term which describes inflammation of the cornea. The cornea is the eye’s outermost lens that covers the iris, pupil and anterior chamber of the eye. It controls and focuses the entry of light into the eye and accounts for about two-thirds the eye’s total focusing power.

Staphylococci, or streptococci infections can be caught from another infected person, or can occur when your eye comes into contact with contaminated objects. Such infections are quite painful and cause eyes to become red and vision to become blurred. If the infection is left untreated, one can even go blind.

3.) Stye — Caused by the staphylococcus bacteria, a stye (a.k.a. hordeolum) is a small, painful bump that grows on the inside or outside of the eyelid. A stye may last several days before it bursts and heals. Before that happens, a stye can be filled with pus and can cause red and painful swelling, depending on its location.

4.) Blepharitis — When oil glands located near the base of the eyelashes become clogged, the result may be an infection and resultant inflammation of the eyelids known as blepharitis. This eye infection is often a chronic condition and it can become quite uncomfortable. The good news is that it is not contagious and it doesn’t cause permanent damage to your eyesight.

Symptoms of blepharitis include: watery red eyes, a burning or stinging sensation in the eyes, a greasy and sticking eyelid, itchy eyelids, crusting, sensitivity to light and even eyelash loss.

Colloidal Silver to the Rescue!

A good solution for preventing infections from contact lenses could be soaking the contacts in small amounts of colloidal silver.

As a matter of fact, many people have reported doing that very thing, and claim to have experienced great results. So I decided to look a bit further into the use of colloidal silver for contact lens users.

Of course, we know colloidal silver can be used in the eyes to stop infections. Tens of thousands of people have done so, worldwide. If you’re unfamiliar with this usage, see:

However, I get a lot of questions from people asking if they can soak their contact lenses in colloidal silver overnight, in order to disinfect them enough to help stop microbial contamination leading to eye infections.

So, let’s begin this article with what actual colloidal silver users have had to say about their experiences with colloidal silver and contact lenses, and then move on to the clinical evidence that silver can help disinfect contact lenses and reduce the risk of eye infections:

Reports from Actual Contact Lens Wearers

Colloidal silver users C.L. posted the following comment on Steve Barwick’s Colloidal Silver Secrets Community on Facebook:

“Just an FYI, I have always had issues with comfort with my contacts. I rarely wear them because they become uncomfortable as soon as I put them in my eye. Well I decided that I was going to spray colloidal silver in my eyes with the contacts in just to see what would happen.

“I am happy to report that I have been able to keep them in all day with no issues. I actually was able to keep them in for about two days with no issues. I am just amazed. I never liked the contact solution that I store them in, so I will be storing them in colloidal silver from now on.”

And from G.W. in Canada:

“We have enjoyed so much experimenting with our colloidal [silver] water and feel so clean inside and out…But the most remarkable change I have noticed is in using the undiluted, regular strength colloidal drops as an eye rinse twice daily.

I use an eye dropper and put several drops in morning and evening. The first two days, my eyes stung slightly, and in the morning I woke up with a slight discharge in the corners of my eyes.

“After that my eyes, which were always bloodshot from years of adverse reactions from wearing contact lenses, with harsh chemicals, and having eye infections, which prescriptions didn’t solve, suddenly were snowy white!

I didn’t think that a 46 year old lady could have snowy white eyes after the problems I had. They are like a healthy young child’s!

“I decided to store my lenses in colloidal silver!! I use ½ of the recommended soaking solution, and distilled water. To that I add 3 drops of colloidal silver and SHAKE. To my amazement — the solution is so gentle — I have no sore eyes anymore!

And one other added blessing: There was a pair of lenses that I could not wear. They had apparently become infected with bacteria. I was going to throw them out. After soaking in my special preparation, they are back to normal. I have saved a pair of lenses that were only 4 months old! Thanks to colloidal silver!”

Another user, this time unnamed, wrote:

“The last 2 nights I have soaked my disposable soft colored lenses in colloidal silver in order to prevent microbial contamination…and it works fine. My only suggestion is to make sure you rinse good with the regular saline solution prior to placing the lenses into your eyes. The colloidal silver really did clean them well… didn’t distort them in any way.”

Here’s another testimonial I came across while researching this article:

“I wear disposable contact lenses that are supposedly good for 14 days @ 12h/day or 7 days @ 24h/days.

For over 2 years now, I am spraying colloidal silver in my eyes every morning and I can wear the same contact lenses easily for 3 to 4 months without ever removing them.

No need to remove them at all to disinfect or clean them and I absolutely don’t have any discomfort in my eyes whatsoever.

This is amazing! I used to spend hundreds of dollars on contacts lenses per year, now a box of 6 is sufficient (If I don’t lose any in the shower or for other reasons). Just wanted to share this… Cheers” — Daniel

And let’s check out one more online testimonial:

“I have been making colloidal silver for a few years now. Don’t use it for much except I put a couple of drops in each contact lens holder. Really keeps them sterile. I can get up to 3 months wear out of a disposable contact lens when 1 month is the norm.

It sort of discolors them after a while but they still wear well. And sometimes when I do feel like I have a little eye irritation from probably rubbing my eyes with non sterile hands, I just put a couple of drops directly in my eyes and clears it right up!”

So there you have it. If the above testimonials are any indication, colloidal silver seems to be a wonderful disinfectant for contact lenses, helping soothe the eyes and keep contact lens-related eye infections at bay.

Of course, regardless of whether or not you choose to experiment with using colloidal silver to help keep your contact lenses disinfected, you should always follow the recommended guidelines for proper care of your lenses (and your eyes).

Can Colloidal Silver Warp Contact Lenses?

Steve Barwick, author of The Ultimate Colloidal Silver Manual, has reported having a reader who claimed his expensive contact lenses “got warped and became unusable” after he soaked them overnight in colloidal silver.

Barwick said this reader’s report initially gave him pause about using colloidal silver to help keep contact lenses disinfected, especially since Barwick has no personal experience with contact lenses (and neither do I).

My suspicion, however, is that too much colloidal silver (or too highly concentrated colloidal silver) might have been used by the reader who posted the negative report.

Looking back to the first-hand testimonials cited earlier in this article, you can see that only three drops of colloidal silver, added to the regular contact lens solution, appears to be quite sufficient.

I’ll repeat very brief excerpts from two of those testimonials here, so you don’t have to scroll back up to look at them:

“I decided to store my lenses in colloidal silver!! I use ½ of the soaking solution, and distilled water. To that I add 3 drops of colloidal silver and SHAKE. To my amazement — the solution is so gentle — I have no sore eyes anymore!

Here’s the other testimonial I mentioned:

“I have been making colloidal silver for a few years now. Don’t use it for much except I put a couple of drops in each contact lens holder. Really keeps them sterile. I can get up to 3 months wear out of a disposable contact lens when 1 month is the norm.”

Try as we might, neither myself nor Steve Barwick could find any further reports of colloidal silver causing contact lenses to warp.

What I did find was that by far the number one reason for contact lenses becoming warped was allowing the lenses to dry out completely. From the National Keratoconus Foundation:

“If your lenses ever dry out, soak them for at least 4 hours before you wear them again, since they may have warped or flattened in curvature when the liquid evaporated. Do not mix and match solutions made by different manufacturers. Doing so may cloud your lenses, cause them to become gummy, or irritate your eyes.”

I also found that the American Academy of Ophthalmology said contact lenses could become warped over time due to the lens wearer’s corneas changing their shape.

Nevertheless, it’s always a good idea to proceed with caution, especially considering the high cost of contact lenses.

If you’re a contact lens wearer, and you choose to experiment with using colloidal silver in your contact lens solution as a means of helping keep microbial contamination to a minimum, consider doing so gingerly, i.e., perhaps start by adding three drops of 10 ppm colloidal silver to your regular contact lens solution rather than soaking your contacts in pure, unadulterated colloidal silver.

But given all of the positive reports from contact lens users, plus what the clinical science has to say about the antimicrobial benefits of adding silver to contact lenses, I have to wonder whether or not the contact lens user who contacted Steve Barwick might have simply allowed their contacts to dry out completely.

And what does medical science have to say about the use of silver in contact lenses? Well, the results of several clinical studies just might surprise the heck out of you. Let’s take a quick look:

What Medical Science Has to Say
About the Use of Silver for Contact Lenses

In June of 2010 a clinical study titled “Ability of silver-impregnated contact lenses to control microbial growth and colonisation” was published in the prestigious Journal of Optometry.

As the study authors explained, the purpose of the study was:

“To examine the ability of silver nano-particles to prevent the growth of Pseudomonas aeruginosa and Staphylococcus aureus in solution or when adsorbed into contact lenses. [And] To examine the ability of silver nano-particles to prevent the growth of Acanthamoeba castellanii.”

In the “Methods” section of the study, the researchers explain that they started by soaking a type of contact lens called “Etafilcon A” in silver nanoparticles. They wrote, “Etafilcon A lenses were soaked in various concentrations of silver nano-particles.”

The researchers went on to state that “Bacterial cells were then exposed to these lenses, and numbers of viable cells on lens surface or in solution compared to Etafilcon A lenses not soaked in silver.

In other words, they exposed bacterial cells to contact lenses soaked in silver nanoparticles as well as to contact lenses not soaked in silver nanoparticles.

Then they directly compared the contact lenses that were not soaked in silver nanoparticles with the contact lenses that were soaked in silver nanoparticles, to see how much bacterial growth there was.

And what did they find? The “Results” section of the study states:

“Silver nano-particle containing lenses reduced bacterial viability and adhesion. There was a dose-dependent response curve, with 10 ppm or 20 ppm silver showing > 5 log reduction in bacterial viability in solution or on the lens surface.”

“Reduced bacterial viability and adhesion” means the silver killed a significant number of bacteria, and also prevented bacteria from adhering to the contact lens surfaces.

A “5 log reduction” means the number of microbes found on the contact lenses treated with silver was 100,000 times less than on the contact lenses not treated with silver. What can you say to that but “Wow!”

In the “Conclusion” section of the study, the researchers concluded:

“Silver nanoparticles are effective antimicrobial agents, and can reduce the ability of viable bacterial cells to colonise contact lenses once incorporated into the lens.”

So there you have it. Modern clinical science has concluded that silver nanoparticles can help reduce the number of microbes colonizing contact lenses, which, of course, would lead to reduced numbers of potential infections!

Another Clinical Study

In another clinical study, this one titled “Antimicrobial efficacy of a silver layer on hydrogel lenses” (originally published in German in the journal Der Ophthalmologe), contact lenses that were specially manufactured with a silver layer (i.e., a layer of the lens impregnated with silver nanoparticles) were examined for their effect on bacteria.

The lenses, called “Wefledx 55 hydrogellenses,” were exposed to Pseudomonas aeruginosa and Staphylococcus aureus, pathogens that are commonly responsible for eye infections among contact lens wearers.

And what did the researchers discover? They discovered that “Lenses with a silver layer showed markedly fewer test organisms than did unprepared lenses.”

The study’s conclusion stated that their “investigations of preserved contact lenses indicate a new possibility for reducing lens-induced infections of the eyes.”

Although not recommending that silver layers on contact lenses be used to replace other sterilization procedures completely, the authors said that such layers “may represent an additional protection from contamination.”

And Yet Another Clinical Study

Another clinical study, titled “Antibacterial Activity of Silver Nanoparticle-Loaded Soft Contact Lens Materials: The Effect of Monomer Composition” was published in 2016 in the journal Current Eye Research.

This study examined the antibacterial activity of “silver nanoparticles-loaded hydrogels” (i.e., soft contact lens materials soaked in a silver nanoparticles solution) against Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus epidermidis (S. epidermidis) which were isolated from patients’ eyes.

The study found that:

“All silver nanoparticle-loaded hydrogels demonstrated excellent antimicrobial effects at all times against P. aeruginosa and S. epidermidis after soaking in 10 and 20 ppm SNP suspensions.”

The researchers further stated that electron-microscope image scanning revealed “excellent inhibitory effect of silver nanoparticles against biofilm formation on the surface of the hydrogels.”

In other words, microbial colonization was inhibited by the silver-impregnated soft contact lenses, and the ability of the microbes to form protective biofilms was also inhibited!

One Last Clinical Study

In February 2017, the study “Synthesis and characterization of nanosilver-silicone hydrogel composites for inhibition of bacteria growth” was described in the Journal of the British Contact Lens Association, Contact Lens and Anterior Eye.

The study authors impregnated “synthesized silicone hydrogel (SiH) films” (i.e., the material used to make soft contact lenses) with 10, 20, 30, 40, 60, and 80 ppm silver nitrate solutions.

They then evaluated the antimicrobial effect of the hydrogels against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus by comparing the numbers of viable bacterial cells on the surface of the silver-impregnated hydrogel material compared to control hydrogel film material that was not impregnated with silver.

This study found that the silver impregnated silicone hydrogel films increasingly inhibited bacterial growth as the concentration of silver was increased. Said the study authors:

“AgNPS incorporated into SiH films reduced the bacterial cell growth and prevented colonization. Groups NAgSiH(R60,R80) demonstrated an excellent reduction in bacterial viability in solution and on the SiH surface.”

The researchers concluded that NAgSiH composites possessed “excellent antimicrobial effects.”

So once again we see that clinical science has demonstrated the ability of silver to inhibit the growth of infection-causing microbes on contact lens materials.

Silver Inhibits Microbial Growth
on Contact Lens Cases, Too!

And now for some additional good news: Recent studies have demonstrated that silver dramatically reduces bacterial growth on contact lens cases, too.

That’s important, because an often-overlooked source of microbial contamination of contact lenses is the contact lens cases they’re stored in.

Cases are commonly recommended to be cleaned and sterilized each time the contact lenses are taken out and used. Otherwise, the cases can become contaminated by microbes, which in turn will contaminate contact lenses stored in the cases.

So let’s look at a couple of studies about silver and contact lens cases:

In 2006 a joint study titled “Clinical and laboratory testing of a silver-impregnated lens case” was published in the journal Contact Lens and Anterior Eye. It described two simultaneous studies on silver impregnated lens cases. The “Purpose” section of the joint study stated that:

“Lens case contamination is a well-documented occurrence for contact lens wearers despite the efficacy of current lens disinfectants. Several microorganisms have a propensity to attach to surfaces and may become more tolerant of disinfection upon attachment.

Non-compliance with disinfection regimens occasionally occurs wherein patients store their lenses in saline or in tap water.

A silver-impregnated lens case was developed in an attempt to decrease case contamination. These studies examine the performance of the case both in vitro and in vivo.”

The “Methods” section described how “Two 40-subject 1-month contralateral clinical studies were conducted with SOLO-care Aqua solution using one bowl of a silver-impregnated case and one bowl of a standard lens case for lens storage. Lens cases were collected and cultured for aerobic bacteria.”

The “Results” section of the study revealed that “the studies found in vitro efficacy data show significantly lower numbers of recovered microbes from silver-impregnated cases than from control cases.”

The study authors went on to say that:

“In both clinical studies, silver-impregnated cases had a statistically significantly lower proportion of bacterial contamination than control cases.

The majority of microorganisms isolated from silver-impregnated cases were members of the normal skin flora.”

Finally, the “Conclusion” of the two studies was:

“The performance of the silver-impregnated case in vitro and the observed lower proportion of contaminated silver-impregnated lens cases in a clinical setting demonstrate the case’s ability to decrease bacterial contamination.”

In another clinical study, this one titled “Biocidal efficacy of silver-impregnated contact lens storage cases in vitro” and published in 2011 in the journal Investigative Ophthalmology & Visual Science, researchers evaluated the performance of three different commercial brands of silver impregnated contact lens cases – MicroBlock, i-clean and Nano-case.

All three brands were found to reduce microbial activity in the lens cases (though the researchers say the MicroBlock case seemed to provide the best protection, which could have been because that particular product had more silver nanoparticles embedded in the material the case is composed of).

So once again we see that silver can be used to prevent microbial contamination of contact lenses, in this case, simply by embedding silver nanoparticles in contact lens cases.

My question is this:

Since commercial colloidal silver disinfectant products sprayed on surfaces have been demonstrated to remain active against pathogens for up to 24 hours or more before the surfaces need to be sprayed again, would simply spraying one’s contact lens cases with a good, high-quality liquid colloidal silver product each night, and allowing it to air dry before putting one’s lenses into the case, provide equal or even superior antimicrobial benefit over the far more expensive silver-embedded lens cases?

My suspicion is that it would.

Why? For the simple reason that you can control how much colloidal silver you’ve sprayed on a contact lens case, but you can’t control how much germ-killing silver is released by embedded silver nanoparticles in a contact lens case.

You see, how much germ-killing silver is released from embedded silver nanoparticles is controlled by a number of factors, including but not limited to: the number of silver nanoparticles embedded in the case, the amount of moisture or humidity those silver nanoparticles are exposed to (so they can oxidize and release germ-killing silver ions) and the amount of bright light those silver nanoparticles are exposed to (again, so they can oxidize and release germ-killing silver ions).

What this means is that while you can purchase contact lens cases that are embedded with silver nanoparticles, how well those silver nanoparticles will help prevent microbial growth is largely dependent upon the three factors mentioned above.

For example, if you own a silver-embedded contact lens case and you store it in your bathroom, more germ-killing silver ions will released on days in which you took a shower in that bathroom (thanks to the added humidity which triggers silver nanoparticles to release germ-killing silver ions) than on days in which you didn’t take a shower in that bathroom.

But simply spraying colloidal silver onto a contact lens case once each day solves that issue of inconsistency completely.

Nevertheless, that’s something you’d have to experiment with, because there are no clinical studies I can find in which metallic silver embedded into a product such as a contact lens case has been tested against colloidal silver sprayed onto a contact lens case. So consider it just my two cents worth.


It looks very much to me like we can add “disinfecting contact lenses” to the ever-growing list of uses for the wonder known as colloidal silver.

Speaking of which, I urge you to check out this important booklet by Steve Barwick:

Here’s how the booklet is described at the Colloids for Life blog:

“This is Steve Barwick’s latest, in-depth 25-page guidebook detailing dozens upon dozens of little-known ways to use colloidal silver, both in the body as well as around the house in order to keep your household and your family infection-free 365 days a year.

C:\Users\Barwick\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Word\44373021_s.jpgImportant Addendum: Where to Find Colloidal Silver

If you’re brand new to colloidal silver usage and are wondering where to buy it, it’s important to know that you can find it in just about any well-stocked health food store in America.  It’s also available on Amazon and numerous other websites.

But it can be extremely expensive. In fact, because colloidal silver works so well against numerous forms of infection and disease, it has the highest price mark-up of any nutritional supplement in existence.

The amount of actual silver in a four-ounce bottle of colloidal silver is about five to 12 cents worth.  (Yes, I said five to twelve cents.)

Yet because that small amount of silver is all it takes to decimate so many different kinds of infections, the manufacturers mark it up about 16,000%, charging a whopping $20 or $30 per bottle.

What’s more, manufacturers promoting the latest faddish colloidal silver product often charge far more per bottle – sometimes $35 to $50 for a tiny four-ounce bottle.

And people are more than willing to pay through the nose for these commercial colloidal silver products at health food stores because colloidal silver does indeed heal infections and prevent the spread of germs and disease faster and better than any other natural supplement on the planet!

So, commercially speaking, the retail price of colloidal silver at health food stores reflects its value to the consumer far more so than its true cost to produce. But here’s the good news:


Make Your Own High-Quality
Colloidal Silver for Pennies!

As I mentioned, typical health food store prices for colloidal silver can range from $20 to $30 for a tiny, four-ounce bottle.

But with a brand new Micro-Particle Colloidal Silver Generator from The Silver Edge, you can make your own safe, pure, high-quality micro-particle colloidal silver for about 36 cents a quart!  In other words, you can make it at actual cost, just like the big colloidal silver bottlers do.

Compared to typical health food store prices, your first two one-quart batches literally pay for the entire cost of your new generator!  Do you know of any other health product that literally pays for itself the very first few times you use it? The savings are absolutely astonishing!

In fact, by making your own high-quality colloidal silver with a brand new Micro-Particle Colloidal Silver Generator from The Silver Edge, you’ll be as close to having FREE colloidal silver as you can get, and for the rest of your life!

You’ll never have to pay those exorbitant health food store prices again!

The new Micro-Particle Colloidal Silver Generator is now the world’s #1 best-selling colloidal silver generator. Here are just a few reasons why you should own one…

  • It pays for itself after your very first batch or two — your total cost to make your first one-quart batch is about 36 cents, compared to the $240 you’d pay at a health food store if you bought an equivalent amount (i.e., eight of those little 4-ounce bottles they normally sell for $30 apiece)!
  • Safe, simple to operate…No special skills needed…You just set the handy timer, plug it in, walk away, and three hours later you have a perfect batch of therapeutic quality micro-particle colloidal silver…every time!  Here’s a short pictorial demonstrating how astonishingly easy it is to use a new Micro-Particle Colloidal Silver Generator from The Silver Edge:

  • Produces uncommonly small silver micro-particles as low as .8 nm. That’s a fraction of a single nanometer. Compare that to health food store colloidal silver which can contain silver particles as large as 200 nm to 1,000 nm (or even larger), and you’ll see why micro-particle colloidal silver is the very best there is!  Smaller particles mean your body can absorb and utilize up to 99% of the colloidal silver you take, compared to maybe 30% or 40% with many health food store brands!
  • Runs on standard household electricity, but uses less power than a tiny Christmas tree bulb – you won’t even see a blip on your electric bill!
  • Produces uniform, crystal clear batches every single time that store for months, or even years, without losing potency!
  • Cannot produce silver chloride or unsafe substances – you get pure, therapeutic-quality micro-particle colloidal silver every time!

Customer Testimonials

Here’s what one customer recently wrote to tell us:

“Owning a Micro-Particle Colloidal Silver Generator from The Silver Edge has given us the luxury of being able to use high-quality colloidal silver any time we need it.  And we never have to worry about the costs because it only costs a few pennies per quart to make!  It is without a doubt the single-best money-saving appliance in my entire house!

Best of all, the machine is very easy to use, and easy to store. I was concerned about ease-of-use, but my fears were unfounded. After I got mine and used it, I immediately bought one and sent it to my 83 year old mom, and she uses it regularly as well.

Now that I have a Micro-Particle Colloidal Silver Generator, I can use colloidal silver for everything — disinfecting the kitchen sinks, countertops, and the cutting board… spraying the toilet bowls, and the bathroom countertops and sinks… spraying it on my toothbrush to prevent bacterial growth…rinsing my mouth with it to prevent cavities and gum disease…you name it.

I even put it in the laundry rinse cycle when I do my linens, towels and kitchen rags, so I don’t have to wash them as frequently. It really keeps them fresh, and there’s never any mold or mildew anywhere in our house.

I also put some in the cat’s water bowl each day, and the dog’s too.  We use it in the bathtub for skin problems.  And of course we drink it when our tummies are queasy, or when we feel a cold or flu coming on.  We also gargle with it in order to get rid of sore throats, and sniff it up our noses to get rid of sinus problems.

My husband even sprays it on his hair in the mornings, and has completely eliminated his lifelong dandruff problem.  And he sprays a little bit in his eyes from time to time, and now has no more recurrent problems with sties.”

— K. Sullivan, NM

And here’s what another happy customer wrote to say about the tremendous savings she’s achieved by no longer having to purchase her colloidal silver through health food stores:

pexels-photo-254069 marie wilkey clone.jpeg

“We make a quart of colloidal silver at least once a week with the Micro-Particle Colloidal Silver Generator from the Silver Edge. I finally sat down and figured out how much this machine has been saving us. By making our own colloidal silver we’ve saved $11,503.20 this year alone, compared to the cost of colloidal silver at our local health food store.

The cost for colloidal silver at our local health food store is $30 for a tiny four-ounce bottle. But with my Micro-Particle Colloidal Silver Generator, I can make eight times that amount (i.e., a full quart) for about 35 cents total cost.

If I were to purchase a quart of colloidal silver at the health food store, which would be eight of those tiny, four-ounce bottles, the cost would be a whopping $240 (i.e., 8 x $30 = $240) compared to the 35 cents I now spend to make a full quart!

Here’s the breakdown of our costs to make a full quart of colloidal silver with our Micro-Particle Colloidal Silver Generator: It costs us about a dollar for a gallon of steam-distilled water at Walmart. So a quart of the steam-distilled water costs about 25 cents. And I estimate we use maybe a nickel’s worth of electricity and maybe another nickel’s worth of silver from the silver rods for every one-quart batch of colloidal silver we make. So that’s 35 cents a quart, all told, for each quart of micro-particle colloidal silver we make!

And frankly, considering how long the .999 fine silver rods have lasted (over a year and a half, so far, for the most recent set), I think it’s probably even cheaper than that. But it’s the lifetime savings we’ve experienced that’s just mind-boggling to me.

For example, we’ve had our Micro-Particle Colloidal Silver unit for nearly five years now. And as I mentioned we make one quart per week, and we spend about 35 cents a week on making colloidal silver.

This means we save about $239.65 a week by not having to purchase a quart’s worth of colloidal silver at our local health food store.  So do the math: In just one month, the savings is $958.60…in one year, the savings is $11,503.20…and in five years we’ve saved approximately $57,516.00!

When you put pencil to paper and figure it out, it definitely takes you by surprise. You just think ‘No way. I must have multiplied that wrong.’

But it’s true. The savings is legitimately well over $11,000 a year over health food store prices for colloidal silver, if you make and use a quart of colloidal silver a week like we do!  And we reap that incredible savings from the very reasonable $250 investment we made in purchasing our Micro-Particle Colloidal Silver Generator.

In their advertising literature, The Silver Edge says the unit completely pays for itself after your first couple of one-quart batches. But really, that’s quite an understatement when you realize the true extent of your savings!

Of course, once you start making your own colloidal silver with a Micro-Particle Colloidal Silver Generator from The Silver Edge, you don’t really think about how much you’re saving compared to health food store prices, because it just becomes a normal part of your everyday life. But the savings is nevertheless astonishing when you reflect on it.

What’s especially nice is being able to produce a significantly higher-quality colloidal silver than what’s generally available to the public through health food stores, especially at such a tiny, tiny fraction of the cost.”

— Marie Wilkey, SC

The Bottom Line…

With a high-quality Micro-Particle Colloidal Silver Generator from The Silver Edge, you’ll never again have to pay exorbitant health food store or internet vendor prices for high-quality colloidal silver!

Indeed, your first batch or two will indeed completely pay for the entire cost of your generator, compared to health food store prices!

What’s more, you’ll be able to give colloidal silver away FREE to family members, friends and neighbors, because you’ll be making it — literally — for only a few pennies per batch!
