Scientific Study Finds That LED Light Bulbs Cause Blindness

A lot of people are thought to be at risk.


A scientific study has uncovered definitive evidence that LED light bulbs used in the home cause people to slowly go blind.

Often consider the eco option for home lighting, researchers have found the LED light bulbs have a seriously detrimental effect on our health.

Dr. Alexander Wunsch, one of the world’s leading experts on photobiology, shares the hidden dangers of LED (light-emitting diode) lighting.

Most people are completely unaware of the risks LED light bulbs pose, yet the impact on health is enormous.

Not only are Dr. Wunsch’s findings crucial in preventing blindness, but also in avoiding sabotaging your health entirely.

LED light bulbs

There’s been a major transition to using LED light bulbs as a primary indoor light source, largely as a result of energy efficiency.

It works like a charm, in this regard, by reducing energy use by as much as 95% compared to lighting from incandescent thermal analog sources.

However, according to Dr. Mercola, the heat generated by incandescent light bulbs, which is infrared radiation, is actually beneficial to your health, and hence worth the extra cost.

There are major downsides to LEDs that are not fully appreciated.

LED light bulbs may actually be one of the most important, non-native EMF radiation exposures you’re exposed to on a daily basis.

If you chose to ignore these new insights, it can have very serious long-term ramifications.

It could lead to age-related macular degeneration (AMD), which is the leading cause of blindness in the United States and elsewhere.

Other health problems rooted in mitochondrial dysfunction may also be exacerbated, and these run the gamut from metabolic disorder to cancer.

What Is Light?

The definition of light, as applied to artificial light sources, is rather distinct. Visible light is only between 400 nanometers (nm) and 780 nm, but “light” is actually more than just what your eye can perceive.

As explained by Wunsch:

“When we look at sunlight, we have a much broader spectral range, from somewhere around 300 nm up to 2,000 nm or so. For our energy efficiency calculation, it makes a big difference if we are talking about this broad natural range or if we are only talking about … vision performance

[T]he definition that we are only looking at the visible part of the spectrum [given in the 1930s] … led to the development of energy-efficient light sources like the fluorescent lamps or what we have nowadays, the LED light sources, because they are only energy efficient as long as you take the visible part of the spectrum [into account] …

[F]or example, [lamps providing] phototherapy with red light can be used in medical therapy to increase blood circulation, and this is a part we are taking away as long as we only look at the visible part.

Physicists think that infrared radiation is just thermal waste. But from the viewpoint of a physician, this is absolutely not true; in the last 30 years there have been hundreds of scientific papers published on the beneficial aspects of a certain part in the spectrum, which is called near-infrared or infrared-A.”

What Makes Near-Infrared so Special?

You cannot feel near-infrared as heat, and you cannot see it, but it has a major beneficial impact in terms of health.

Near-infrared is what’s missing in non-thermal artificial light sources like LED.

There’s also a difference between analog and digital forms of light sources, and this difference is another part of the complexity.

In essence, there are two separate but related issues: the analog versus digital light source problem, and the spectral wavelength differences.

Starting with the latter, when you look at the rainbow spectrum, the visible part of light ends in red.

Infrared-A or near-infrared is the beginning of the invisible light spectrum following red.

This, in turn, is followed by infrared-B (mid-infrared) and infrared-C (far-infrared).

While they cannot be seen, the mid- and far-infrared range can be felt as heat.

This does not apply to infrared-A, however, which has a wavelength between 700 and 1,500 nm.

“Here you have only very low absorption by water molecules, and this is the reason why radiation has a very high transmittance,” Wunsch says.

“In other words, it penetrates very deeply into your tissue, so the energy distributes in a large tissue volume. This near-infrared A is not heating up the tissue so you will not feel directly any effect of heat.

This significantly changes when we increase the wavelength, let’s say, to 2,000 nm. Here we are in the infrared-B range and this already is felt as heat. And from 3,000 nm on to the longer wavelength, we have almost full absorption, mainly by the water molecule, and this is [felt as] heating.”

Near-Infrared Is Critical for Mitochondrial and Eye Health

The near-infrared range affects your health in a number of important ways.

For example, it helps prime the cells in your retina for repair and regenerate.

Since LEDs have virtually no infrared and an excess of blue light that generates reactive oxygen species (ROS), this explains why LED light bulbs are so harmful to your eyes and overall health.

Chromophores are molecules that absorb light.

There’s an optical tissue window that ranges from 600 to 1,400 nm, which means it is almost completely covered by the infrared-A part of the spectrum.

This optical tissue window allows the radiation to penetrate several centimeters or at least an inch or more into the tissue.

Chromophores are found in your mitochondria and inactivated water molecules.

In your mitochondria, there’s also a specific molecule called cytochrome c oxidase, which is involved in the energy production within the mitochondria.

Adenosine triphosphate (ATP) — cellular energy — is the end product.

ATP is the fuel your cells need for all of their varied functions, including ion transport, synthesizing and metabolism.

Remarkably, your body produces your body weight in ATP every day. And, while you can survive for several minutes without oxygen, were all ATP production to suddenly stop, you’d die within 15 seconds.

Lighting Plays an Important Role in Biological Energy Production

This is why this issue of lighting is so important. Light is a sorely misunderstood and overlooked part of the equation for biological energy production, specifically at the mitochondrial ATP level. As further explained by Wunsch:

“The cytochrome c oxidase, which is this [light] absorbing molecule, is the last step before the ATP is finally produced in the mitochondria. Here we have this tipping point where light in a wavelength range between 570 nm and 850 nm is able to boost energy production, especially in cells when energy production is depleted …

We know today that many signs of aging, for example, are the consequence of hampered mitochondrial functioning, and so we have a very interesting … tool to enhance the energy status in our cells, in the mitochondria in our cells, and not only on the surface but also in the depths … of the tissue. This is one important aspect and there are hundreds of papers published on these positive effects …

Infrared saunas are another magnificent way to nourish your body with near-infrared light.

But not just ANY infrared sauna.

Most offer only FAR-infrared and are not full spectrum.

Most also emit dangerous non-native EMFs.

So you need one that emits low or no non-native EMFs.

After searching for a long time I finally found a near perfect one and hope to have it made to my customized specs in a few months.

And it should be significantly less than $1,000. So stay tuned for this exciting development.

Wound Healing and Anti-Aging Procedures Make Use of Near-Infrared


These beneficial effects can be seen in wound healing and anti-aging procedures where near-infrared is employed.

Since the cytochrome c oxidase is responsible for an increased production of ATP, the cell has a better supply of energy, which allows it to perform better, and this is true no matter where the cell resides.

This means liver cells with more ATP will be able to detoxify your body more efficiently; fibroblasts in your skin will be able to synthesize more collagen fibers and so on because ATP is crucial for all cellular functions.

Wunsch expands on this even more in the lecture above.

According to Wunsch, as little as one-third of the energy your body requires for maintaining the thermal equilibrium comes from the food you eat.

The electrons transferred from the food, primarily the fats and the carbohydrates, are ultimately transferred to oxygen and generate ATP.

The more near-infrared you get, the less nutritional energy is required for maintaining thermal homeostasis.

That said, a differentiation is in order.

Most of the METABOLICALLY USED energy does come from food.

But there is a thermodynamic aspect to it as well.

Maintaining a normal body temperature (37 degrees C or 98.6 degrees F) involves two mechanisms: Energy production in your mitochondria from food, and photonic energy (near-infrared radiation from sunlight and incandescent light bulbs) that is able to penetrate deeply into your tissue, even through clothing.

“The radiation can enter your body and then be transformed into longer wavelengths in the infrared part. They are very important for supporting the temperature level, the thermal energy level, of our body which is … a very crucial aspect. A lot of energy comes in the form of radiation and this is supporting our thermal balance,” Wunsch explains.

The key take-home message here is that your body’s energy production involves not just food intake.

You also need exposure to certain wavelengths of light in order for your metabolism to function optimally.

This is yet another reason why sun exposure is so vitally important for optimal health.

Analog Versus Digital Lighting

LED light bulbs in lamps are a form of digital non-thermal lighting whereas incandescent light bulbs and halogens are analog thermal light sources.

You’ve likely experienced this if you’re old enough to recall the older TVs that had a very visible and intense flicker.

Modern flat screens do not have this perceptible flicker, but they’re still switching on and off.

Scientists are now trying to develop systems capable of transmitting information via high-frequency flicker in the LED light bulbs to replace the wireless LAN system.

According to Wunsch, this is a very bad idea, from a health perspective.

Unfortunately, the use of LEDs has been mandated by federal policy in both the U.S. and much of Europe, in an attempt to conserve energy.

While inarguably effective in that regard, the biological impact of these bulbs has been completely ignored, and by mandating them, options have been restricted.

Understanding the Dangers of LEDs

Understanding how LEDs can harm your health begins with the recognition that light emitted from LED light bulbs is of a different quality than a natural light source.

Normally, a natural light source is a black body radiator that gives off all kinds of wavelengths in a more or less continuous manner.

LEDs are fluorescent lamps, consisting of a blue LED, a driver LED, and a fluorescent sheet that covers the blue LED, transforming part of the blue light into longer wavelengths, thereby creating a yellowish light.

The yellowish light from the fluorescent layer combines together with the residual blue light to a kind of whitish light, a large portion of which is an aggressive blue light.

You probably know by now that blue light in the evening reduces melatonin production in your pineal gland.

But you also have cells in your retina that are responsible for producing melatonin in order to regenerate the retina during the night.

If you use LED light bulbs after sunset, you reduce the regenerative and restoring capacities of your eyes.

Needless to say, with less regeneration you end up with degeneration. In this case, the degeneration can lead to AMD, which is the primary cause of blindness among the elderly.

However, and this is that most fail to appreciate, LED light exposure that is not balanced with full sunlight loaded with the red parts of the spectrum is always damaging to your biology.

Just more so at night.

So, to summarize, the main problem with LEDs is the fact that they emit primarily blue wavelengths and lack the counterbalancing healing and regenerative near-infrared frequencies.

They have very little red in them, and no infrared, which is the wavelength required for repair and regeneration.

When you use these aggressive lower frequencies — blue light — it creates ROS that, when generated in excess, causes damage.

So when using LEDs, you end up with increased damage and decreased repair and regeneration.

Are There Any Healthy LEDs?

There’s a wide range of LED light bulbs on the market these days.

Some are cool white, others are warm white, for example.

The former emits higher amounts of harmful blue light.

The warm LED light bulbs can be deceptive, as they give out a warm-appearing light but do not actually have the red wavelength.

The warmth comes from masking the blue with high amounts of yellow and orange.

There are also LEDs available with less blue, which are closer to the spectral distribution of incandescent lamps with regard to the blue part of the spectrum.

Unfortunately, without tools to measure it, you won’t know exactly what you’re getting.

This is in sharp contrast to an incandescent light bulb, where you know exactly what kind of light spectrum you’re getting.

How to Identify a Healthier LED

So, when buying LEDs, one way to get a healthier light is to look at the CRI.

Sunlight is the gold standard and has a CRI of 100. So do incandescent light bulbs and candles.

What you’re looking for is a light that has an R9 (full red spectrum) CRI of about 97, which is the closest you’ll ever get to a natural light with an LED.

Another factor to look at is the color temperature.

There are two different kinds of color temperature:

1. Physical color temperature, which means the temperature of your light in degrees Kelvin (K). This applies to sunlight, candlelight, incandescent lamp light and halogens.

What this means is that the source itself is as hot to the touch as the color temperature given.

The sun, for example, which has a color temperature of 5,500 K, has a temperature of 5,500 K at its surface, were you to actually touch the sun. Incandescent lamps have a maximum of 3,000 K, as the filament would melt if the temperature got any higher.

2.Correlated color temperature. This is a measurement that tells you how the light source appears to the human eye.

In other words, it is a comparative measurement.

A correlated color temperature of 2,700 K means it looks the same as a natural light source with a physical color temperature of 2,700 K.

The problem here is that while such a light LOOKS the same as a natural light, it does not actually have the same quality, and your body, on the cellular level, is not fooled by what your eye sees.

On a cellular level, and on the level of the retina, the majority of the light is still cold, bluish white, despite its appearance, visible warmth.

Incandescent light bulbs have a color temperature of 2,700 K whereas LED light bulbs can go up to 6,500 K — the really bright white LED.

In this case, the closer you are to incandescent, the better.

Lastly, there’s the digital component, which is virtually unavoidable no matter what.

To determine how good or bad a particular LED is:

A simpler way would be to purchase a flicker detector, which is available fairly inexpensively.

Another way to determine the flicker rate would be to use the slow-motion mode on your camera.

Record the light source in slow motion mode and check it for visible flickering.

Unfortunately, it doesn’t always work.

Some newer cameras and smartphones have a built-in algorithm that will detect the flicker frequency and change the shutter speed accordingly to improve the recording, thereby eliminating the interference.

If your camera has this algorithm, it will not record a visible flicker even if it’s there.

Healthier Solutions

I like being on the cutting edge of technology and I quickly switched out all my incandescent bulbs for LED light bulbs.

I now realize the enormity of my mistake, but at the time — going back almost 10 years now — I was completely unaware that it could have health consequences.

Before that, I used full-spectrum fluorescents, which is equally deceptive, as it is a full spectrum in name only.

I’m now convinced LED light bulbs exposure is a very serious danger, especially if you are in a room without natural light.

The biological risks are somewhat mitigated if you have plenty of sunlight streaming through windows.

At night, LEDs become a greater danger no matter whether you’re in a windowless room or not, as there is no counterbalancing near-infrared light.

Personally, I’ve not swapped all my lights back to incandescent because they’re such energy hogs.

But all the lights I have on at night have been switched to clear incandescent bulbs without any coating that changes their beneficial wavelengths.

So the take-home message of this interview is to grab a supply of the old incandescents if you can and switch back to incandescent light bulbs.

Just remember to get incandescents that are crystal clear and not coated with white to give off a cool white light.

You want a 2,700 K incandescent, thermal analog light source.

Actually, fragrance-free candles would be even better.

Be particularly mindful to only use this type of light at night.

After sunset, I also use blue-blocking glasses.

Low-voltage halogen lights are also very energy efficient — up to 100 percent more energy efficient than the standard incandescent lamp.

Just be sure to operate it in DC.

Incandescent lights, including halogen, can be operated at both AC and DC, but when operating on AC, you end up generating dirty electricity, Wunsch explains.

On DC, you get no electrosmog with a low-voltage halogen.

Light Comparisons

The following graphic illustrates the differences in color spectrum between an incandescent light, which has very little blue, compared to fluorescent light and white LED light bulbs.

Scientific Study Finds That LED Light Bulbs Cause Blindness

This next graph illustrates the differences between daylight, incandescent, fluorescent, halogen, cool white LED light bulbs and warm white LED.

As you can see, there’s a tremendous difference between incandescent and warm LED.

While they may look the same to the naked eye, there’s no comparison when it comes to their actual light qualities.

Scientific Study Finds That LED Light Bulbs Cause Blindness

Looking at the spectral differences between incandescent and halogen lamps, there seems to be no difference at all.

In order to elucidate the disparity, Wunsch did some measurements of incandescent and halogen lamps using his UPRtek MK350S spectrometer.

The differences are almost imperceptible, indeed.

Scientific Study Finds That LED Light Bulbs Cause Blindness

The spectrum of a standard incandescent lamp: Correlated color temperature (CCT) = 2890 K.

Scientific Study Finds That LED Light Bulbs Cause Blindness

The spectrum of an energy saving halogen lamp: Correlated color temperature (CCT) = 2842 K.

How to Make Digital Screens Healthier

When it comes to computer screens, Wunsch suggests reducing the correlated color temperature down to 2,700 K — even during the day, not just at night.

Many use f.lux to do this, but I have a great surprise for you as I have found a FAR better alternative that was created by Daniel, a 22-year-old Bulgarian programmer that Ben Greenfield introduced to me.

He is one of the rare people that already knew most of the information in this article.

So he was using f.lux but was very frustrated with the controls.

He attempted to contact them but they never got back to him.

So he created a massively superior alternative called Iris.

It is free, but you’ll want to pay the $2 and reward Daniel with the donation.

You can purchase the $2 Iris software here.

OLED screen technology is another development that may be better than conventional screens.

To Protect Your Health and Vision, Stick to Incandescent Lights

LED light bulbs are a perfect example of how we’re sabotaging our health with otherwise useful technology.

However, with knowledge, we can proactively prevent the harm from occurring.

In summary, we really need to limit our exposure to blue light, both during the daytime and at night.

So for nighttime use, swap out your LED light bulbs for clear bulb incandescents, or low-voltage incandescent halogen lights that are run on DC power.

I also strongly recommend using blue-blocking glasses after sundown, even if you use incandescent light bulbs.

Without these modifications, the excessive blue light from LED light bulbs and electronic screens will trigger your body to overproduce ROS and decrease the production of melatonin, both in your pineal gland and your retina, the latter of which will prevent repair and regeneration, thereby speeding up the degeneration of your eyesight.

Another healthy light alternative to LED light bulbs

Candles are even a better light source than incandescent bulbs, as there is no electricity involved and is the light that our ancestors have used for many millennia so our bodies are already adapted to it.

The only problem is that you need to be very careful about using just any old candle as most are toxic.

As you may or may not know, many candles available today are riddled with toxins, especially paraffin candles.

Did you know that paraffin is a petroleum by-product created when crude oil is refined into gasoline?

Further, a number of known carcinogens and toxins are added to the paraffin to increase burn stability, not including the potential for lead added to wicks, and soot invading your lungs.

To complicate matters, a lot of candles, both paraffin, and soy, are corrupted with toxic dyes and fragrances; some soy candles are only partially soy with many other additives and/or use GMO soy.

There seems to be a strange mindset that exposure to small amounts of toxins is OK, even though the exposure is exponential over time!

The soy is non-GMO, is clean burning without harmful fumes or soot, is grown in the U.S. and is both sustainable and renewable.

Good candles are completely free of dyes.

The soy in these candles is not tested on animals, is free of herbicides and pesticides.

It’s also kosher, 100 percent natural and biodegradable.

Fragrances are body safe, phthalate- and paraben-free, and contain no California prop 65 ingredients.

The wicks are simply flat braided cotton coated in a natural vegetable wax and self-trimming, which reduces carbon build up.

Enjoying a Circle of Life Farms naturally good soy candle and following the simple burn instructions — located inside the candle lid — will give approximately 70+ hours of burn time. Every candle is hand-poured with love for you to enjoy a cooler, cleaner burn, all while being kind to both the environment and yourself.

You can search online healthy candles, but if you like, you can use the ones I found at www.circleoflifefarms.com.

This is not an affiliate link and I earn no commissions on these candles; I just thought you might benefit from the ones I now use in my home.
