Increased energy at the cellular level means that your body disposes of waste more expediently and your overall bodily energy is increased. This translates to improved stamina, endurance, strength, and speed, and a rise to your peak performance level. Read more benefits here.

Increased cellular energy activates the production of fibroblasts (specific connective tissue cells that create collagen and elastin). Collagen and elastin are the proteins responsible for maintaining your skin’s elasticity and suppleness, and they are also key players in your body’s natural healing process. Enhanced collagen and elastin levels result in your body having a heightened ability to heal itself, triggered at the cellular level.

Overall, a variable ND filter is a valuable tool for photographers and videographers, providing them with greater creative control over exposure and allowing them to capture stunning images in various lighting conditions.

Virtually any condition or disease can derive some level of benefit from red light therapy because your body’s natural healing capacity is maximized. Increased cellular energy drives your body to perform at its highest level.

Regardless of which wavelengths you ultimately choose for yourself, one of the best aspects of red light therapy is that it is easily administered at home. No expensive, time-consuming medical or spa appointments are required, and you need only purchase your device(s) once so there are no recurring costs.

A variable neutral density (ND) filter is a versatile tool used in photography and videography to control the amount of light entering the camera lens. It consists of two polarizing filters that are stacked together and can be rotated relative to each other. The optical principles behind variable ND filters involve the manipulation of light polarization and the reduction of light intensity.

This versatility makes them an essential tool for achieving the desired exposure in various shooting conditions.

630nm and 660nm are the red wavelengths that deliver optimal weight loss and fat-burning assistance. Anywhere in the 630 – 700nm range is effective, but 630 and 660 specifically are especially effective in a combined treatment plan with near-infrared light.

Depending upon your unique needs, you might only want one specific wavelength or you might feel that a combination of several will pave your best route to success. The right device for one person is not necessarily right for another.

Clinical research proves that red light therapy is useful in treating numerous conditions and diseases. There are, in fact, hundreds of studies; far too many to list in this article. Here are some good examples of research that explores and demonstrates the efficacy of red light therapy using a variety of wavelengths for a wide range of purposes.

Muscle growth is compounded through ATP production and the resulting cellular energy boost. Your body’s new ability to work out more intensely naturally invokes a higher level of muscle development, and your muscle mass increases steadily.

An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.

The primary function of a variable ND filter is to reduce the amount of light reaching the camera sensor without affecting the color or quality of the image. This is achieved by rotating the front and rear polarizing filters in opposite directions. When the filters are aligned, they allow maximum light transmission, but as they are rotated, they start to block the light, resulting in a darker image.

I’m hoping to find something that will “nourish” the nerves in my feet as I have peripheral neuropathy. No doctor I’ve asked has any recommendation for this condition. None of the info in your articles mentions neuropathy.

It is important to note that variable ND filters may introduce some color cast or image degradation, especially at extreme density settings. However, advancements in filter technology have significantly reduced these issues in modern variable ND filters.

Because of its thermal properties, infrared light has the capability of burning your skin and causing eye or other bodily tissue damage (unlike red light, which is safe for eyes). For this reason, infrared light must be administered carefully and diligently. It is usually used only in more extreme circumstances, not for routine red light therapy.

First, it is important to understand that each individual is unique, and what works for one person might not be best for another. This applies to specific wavelengths, combinations of wavelengths, and types of devices. No two people are exactly alike, and everyone reacts differently to red light therapy. Utilizing a personalized strategy is best.

Blue light is much lower on the spectrum of visible light than red light. Its wavelengths are only approximately 380 – 500nm.

The variable ND filter works by selectively blocking certain wavelengths of light. As the filters rotate, they align or cross-polarize the light waves, allowing only a fraction of the light to pass through. This adjustable light reduction enables photographers and videographers to achieve longer exposure times, wider apertures, or use slower shutter speeds even in bright conditions.

Before getting into specific red light wavelengths and what they effectively treat, it is important to understand what the basic types of red light are. Classification is based upon the location of the wavelengths on the electromagnetic spectrum. The red light therapy spectrum begins with red light, progresses to near-infrared (NIR) light, and advances to infrared light.

Red light wavelengths are administered to (shined upon) your skin and they penetrate to the cells below. Your mitochondria (the energy production centers or “powerhouses” of your cells) are stimulated, triggering the production of adenosine triphosphate (ATP). ATP is an organic compound within your body that is responsible for all biochemical energy transfer. It is frequently referred to as the “molecular currency” by which cellular energy is transferred throughout your body.

A variable neutral density (ND) filter is a type of camera filter that allows you to adjust the amount of light entering the lens without affecting the color or quality of the image. It consists of two polarizing filters that are stacked together and can be rotated relative to each other. By rotating the filters, you can control the amount of light that passes through them.

Your personal goals and the severity of the condition(s) you wish to treat will dictate which wavelengths are best for you. For example, red light at 630 or 660 nm or a combination of red light and NIR light at 830 nm might be appropriate for someone who hopes to improve general skin health or treat mild acne. A higher-range NIR level (800 to 850 nm) might be a better option for someone treating a more serious condition or focusing on deep tissue and joint health.

NIR light penetrates more deeply into your body than red light, but less deeply than infrared light. NIR light is safer than infrared light because although it borders on the thermal range, its potential to burn your skin or cause deep tissue damage is much lower than that of infrared.

Hello! It was mentioned that 780 nm is a wavelength that helps thyroid health but I didn’t see a device that uses that wavelength. Can you point me in the right direction to locate the device with the 780 nm please? Thanks

The variable ND filter works by selectively blocking certain wavelengths of light, resulting in a reduction of overall light intensity. This allows photographers and videographers to achieve longer exposure times or wider apertures in bright conditions without overexposing the image. It also enables the use of slower shutter speeds, which can create motion blur effects or smooth out water and clouds.

Red light is best suited for treating skin conditions, mild inflammation, and accelerating surface wound healing. There are no adverse side effects to short red light. It cannot burn your skin or damage any underlying body tissues.

Red light therapy is also growing in popularity with celebrities interested in staving off wrinkles and maintaining a glowing, youthful appearance. Notable big-name personalities who use red light therapy regularly for anti-aging purposes include Jessica Alba, Kate Hudson, Kim Kardashian, Emma Stone, Chrissy Teigen, and Katy Perry.

Red light therapy is a convenient at-home treatment that can be personalized to your individual needs through the use of varying wavelengths. Whether you seek to treat a disease, relieve pain, reduce wrinkles, improve athletic performance, or utilize it for one of its practically countless other uses, red light therapy is a powerful tool that will help you achieve your health and appearance goals, both specific and general.

A variety of at-home red light therapy devices are available, some offering multiple wavelength options. Some devices offer just one wavelength, some administer multiple wavelengths at once, others offer the option of administering different wavelengths at different times, and some offer a combination of functionalities. Multi-wavelength devices allow for flexibility and an individualized, customizable approach to treatment.

My husband has a lot of shoulder pain due to a tear and also a lot of neck pain from spurs in his neck. How would he use one of these lights.

Variable ND filters are particularly useful in situations where the lighting conditions change rapidly or when shooting in bright environments. They eliminate the need for carrying multiple fixed ND filters of different densities, providing convenience and flexibility.

The latest advancements in variable ND filters include improved coatings to reduce reflections and flare, as well as better color accuracy and image quality. Some filters also feature a range scale or markings to help photographers and videographers precisely adjust the ND value.

That being said, specific wavelengths and combinations of wavelengths are most prevalent and widely-used for certain objectives. A combination of red and NIR light generally creates the best formula for success. Infrared light also sometimes enters the mix, but much less frequently because of its intensity (read more about the importance of beam angle in red light therapy).

Budget should also be a contributing factor in your decision-making process. The larger and more complex the device, the more it will usually cost.

The wavelengths that are proven to have a profound impact on athletic performance, muscle-building, and recovery are 630, 640, 660, 670, 750, 810, 850, 900, and 980.

In conclusion, the optical principles behind variable ND filters involve the manipulation of light polarization and the reduction of light intensity. By rotating two polarizing filters, photographers and videographers can control the amount of light entering the camera lens, allowing for creative exposure and aperture settings in various lighting conditions.

Infrared light is used mainly to treat serious conditions such as traumatic brain injury, severe pain, Alzheimer’s Disease and other neurodegenerative disorders, and to enhance the effects of chemotherapy during cancer treatment.

ATP is delivered to all of your bodily tissues and organs, elevating the energy level within your cells. Greater energy in your cells elicits higher oxygen levels, reduces inflammation, boosts your immune system, and improves your circulation.

Short red LED wavelengths will only affect fat cells that reside very closely beneath the skin. This, however, is actually where the greatest content of body fat is stored (including but not limited to cellulite), so red LED light will go a long way toward fat-burning.

Red light therapy is growing in use by professional athletes in a wide range of sports and is increasingly being recommended by professional fitness trainers. Its performance-enhancing and healing possibilities enable at-home fitness enthusiasts and professional athletes alike to achieve their ultimate individual performance abilities.

Whatdoes a variable ND filterdo

Even stem cells within your bone marrow are stimulated and are deployed to the injury or wound site via red light therapy. This is significant because cells that are within close proximity to one another will communicate. Damaged cells at an injury site can potentially send harmful signals to neighboring cells, causing infection or prolonging healing time. Healthy stem cells, however, send the right message to damaged cells, signaling them to adapt to the properties of the newly arrived healthy cells.

Inflammation is a predominant cause of pain, so red light therapy’s anti-inflammatory properties provide quick relief of any type of bodily pain. Better circulation, increased cellular oxygenation, better cellular nutrition, and improved ATP levels in your organs and tissues all result in pain relief.

Since the effectiveness of light therapy depends upon how deeply the wavelengths can penetrate your body, the healing capacity of blue light will be much lower than that of red. Blue light waves are only capable of penetrating to a depth of about 1 to 4 mm beneath your skin, as compared to the 8 to 10 mm achieved by even the shortest of red wavelengths.

Skin elasticity and hydration are improved, minimizing the appearance of unsightly scars. Red light therapy will help to some degree with any level of scarring.

Again, because the spectrum is continuous, there is no “magic number” marking the exact beginning or end of NIR light on the spectrum. It is generally agreed upon that NIR light ranges from about 700 to 900 nm in wavelength.

Red light therapy is an emerging method of treating an almost infinite array of physical and mental health conditions and concerns. Its revolutionary healing properties and health benefits are increasingly recognized as successful in a wide range of applications including:

Red light therapy can take years off of your face and clear up skin problems. Some facial and all-over bodily skin conditions that can be treated include:

Red light therapy provides great support for brain health. Brain cell function is improved, thus enhancing overall brain function. Red light therapy can increase mental stamina and cognitive abilities, treat psychiatric disorders and assist with the healing of a stroke (also known as a “brain attack” during which blood flow to an area of the brain is cut off).

The enhanced circulation quality stimulated by red light therapy increases the conveyance of oxygen, white blood cells, and nutrients to the wound or injury site, promoting healing even further.

When light passes through the first polarizing filter, it becomes polarized in a specific direction. As the light travels through the second polarizing filter, which is oriented perpendicular to the first, it encounters resistance. By rotating the second filter, the amount of resistance can be adjusted, allowing more or less light to pass through.

The two polarizing filters are made of high-quality optical glass and are mounted in a rotating frame. The front filter is fixed, while the rear filter can be rotated to adjust the density of the filter. As the rear filter is rotated, it changes the angle at which light passes through the filters, thus altering the amount of light that reaches the camera sensor.

Cellulite (lumpy fat deposits with a dimpled, cottage cheese appearance) also resides directly beneath your skin, so blue light might also be relatively useful in cellulite reduction.

Red light therapy draws upon your body’s natural cellular processes to activate change and help you become your healthiest, fittest, and most radiant self.

The shorter the wavelength and the lower on the spectrum, the less effective light is at penetrating your body to a significant cellular level to stimulate change and healing.

The shortest of all red + NIR wavelengths, red light (also known as short red light) ranges in length from approximately 600 to 700 nm.

While red light has no harmful side effects but infrared light potentially can, NIR light falls somewhere in between. As long as near-infrared light is administered safely and carefully, however, great benefits can be realized with very minimal risk of adverse side effects.

810, 830, and 850nm are the optimal near-infrared wavelengths to use in a broad-based therapy plan including both red and near-infrared light.

The polarizing filters work by selectively blocking certain wavelengths of light. When the filters are aligned, they allow maximum light transmission, resulting in a lower density. As the rear filter is rotated, it starts to block more light, increasing the density. This allows photographers and videographers to have precise control over the exposure by adjusting the amount of light entering the lens.

Red light therapy also impacts your thyroid health. Your thyroid gland is responsible for regulating your metabolism. With better thyroid function, your body is restored to a better hormonal balance and you will be able to lose weight more quickly and easily.

Red light therapy can stimulate your metabolism, burn fat, and reduce cellulite. It can also decrease your appetite and help you reach your peak physical fitness and performance levels. A boost to your metabolism and better exercise performance will accelerate the effects of a healthy diet and exercise program. To read more on how red light therapy works on body fat, click here.

Since the light spectrum is continuous, there is no fixed metric for the exact beginning of infrared light. In general, wavelengths ranging from about 900 to 1400 nm are considered to be infrared.

The first polarizing filter blocks a certain amount of light, while the second filter can be rotated to either block or allow more light to pass through. When the filters are aligned, they allow maximum light transmission, and as they are rotated relative to each other, the amount of light passing through decreases. This adjustable light reduction is what makes the variable ND filter versatile and useful in various photography situations, such as capturing long exposures or achieving a shallow depth of field in bright conditions.

How does a variable nd filter workfor photography

Cerebral blood flow is increased, inflammation is reduced, stem cell production is revitalized, and metabolic cell function is improved via red light therapy. A process called neurogenesis is also stimulated. Neurogenesis refers to the regrowth of neurons within your brain. Neurons are fundamental brain and nervous system units that are responsible for receiving sensory input and sending appropriate signals to the rest of your body. Your brain gains a greater ability to form neural connections and function at a higher capacity.

Near-infrared light is a powerful tool for promoting deep tissue healing and reducing inflammation. It reaches fat cells that reside deeper than the cellulite layer, thereby increasing your total fat-burn.

Bestvariable ND filter

Red light therapy is 100 percent natural and FDA-approved. It contains no harmful ultraviolet (UV) radiation and is safe for all ages and skin types.

If you plan to use red light therapy for its overall bodily benefits and most typical applications (anti-aging, skincare, muscle and joint health, pain relief, and other routine purposes), your best bet is likely to be a device that provides a combination of wavelengths between 630 to 670 nm and 800 to 850 nm. If you are targeting more specialized needs, you will benefit by looking into devices with other wavelengths.

Here is a partial list of additional conditions and diseases along with the specific wavelengths (in nm) that are effective in their treatment.

As your skin cells soak up the red light, the resulting increase in cellular energy and collagen production kills acne-causing bacteria and promotes healing. Red light reduces inflammation and improves oxygen flow to your cells, allowing them to function better. Decreased swelling and inflammation reduces the size of acne pimples, and lower bacteria levels prevent new pimples from forming.

The latest advancements in variable ND filters have focused on improving image quality and reducing color cast. High-quality filters use multi-coating techniques to minimize reflections and flare, ensuring accurate color reproduction. Additionally, some filters employ advanced materials and manufacturing processes to maintain consistent density across the entire filter surface, avoiding any uneven light reduction.

An integrated approach combining red light and NIR light provides a powerful recipe for therapeutic success. The penetration of various wavelengths to multiple depths within your body allows separate and diverse issues to be treated at the same time. For example, skin conditions and deep tissue injuries or joint pain can all be treated at once.

Because red light therapy stimulates your body at its cellular level, individual cells work to boost the functioning of all of your bodily systems. The increased ATP being delivered to your tissues and organs elevates your body’s natural ability to heal itself.

Infrared light is invisible to the human eye. It is the longest form of red light on the spectrum, and it feels hot on your skin (similar to or hotter than sunlight). Infrared light qualifies as light energy, but you can only feel infrared light, not see it. For this reason, it is sometimes referred to as infrared heat. Infrared light is technically classified as thermal energy, meaning that it is heat-producing.

The latest advancements in variable ND filters include improved optical coatings to minimize reflections and flare, as well as enhanced durability and ease of use. Some filters also feature a range of stops or density markings, allowing for precise adjustments and repeatability.

Your ability to concentrate is improved, thinking and problem-solving skills are elevated, and overall mental sharpness and acuity are raised to new levels.Depression, anxiety, and the symptoms of other mental illnesses can be lessened. Even degenerative brain diseases like Alzheimer’s Disease can benefit from red light therapy.

The elevated collagen and elastin production and hydration activated by red light therapy create an increased immune response, eliminating dead skin cells and repairing damaged ones. Wrinkles are minimized to restore your skin to a firmer, smoother texture. Discolorations are reduced, giving your skin a more uniform appearance. A healthy, glowing skin tone is restored, diminishing the appearance of age spots and dark under-eye circles alike.

As with red light, a certain range of NIR wavelengths exhibit greater therapeutic benefits than the remainder. 800 to 880 nm NIR light demonstrates the highest healing potential within its range.

Better circulation creates more capillaries (tiny blood vessels) to deliver oxygen and essential nutrients to your cells. Increased oxygenation and cellular nutrition result in less muscle damage during workouts. This means that you can boost your workout level, experience less exhaustion, sustain less tissue injury, and recover more quickly after exercise.

Short red light penetrates your body to a depth of about eight to 10 millimeters, reaching the mitochondria of your skin cells and other cells that are located closely beneath your skin. Red light does not create heat, although you might experience a mild and pleasant warm sensation on your skin during therapy.

A variable neutral density (ND) filter is a versatile tool used in photography and videography to control the amount of light entering the camera lens. It consists of two polarizing filters that are stacked together and can be rotated relative to each other. The rotation of these filters allows for the adjustment of the amount of light that passes through the lens.

All wavelengths of red LED light will provide benefits, but wavelengths from 630 to 680 nm demonstrate the most healing power.

The visibility of near-infrared light varies. It borders on the high end of the red light range and the low end of the infrared light range; therefore, NIR light is visible at the bottom of its range and invisible at the top of its range. It transitions from visible to invisible somewhere near the high end of its range.

Red light waves with lengths of 630, 650, 660, 670, 720, 780, 810, 830, 900, and 980 all help promote faster healing of wounds and injuries.

Near-Infrared light occupies the area of the spectrum between short red and infrared light. It is somewhat of a “gray area” in the world of red light but is found to be extremely useful for therapeutic purposes.

The variable ND filter works by selectively blocking certain wavelengths of light. When light passes through the first polarizing filter, it becomes polarized in a specific direction. As it reaches the second filter, the orientation of the polarized light determines how much of it is allowed to pass through. By rotating the second filter, the orientation of the polarized light changes, thus controlling the amount of light that reaches the camera sensor.

The first polarizing filter is fixed and acts as a base. The second filter is rotatable and can be adjusted to control the intensity of light passing through the lens. When the two filters are aligned, they allow maximum light transmission, resulting in a low ND value. As the second filter is rotated, it starts to block some of the light, gradually increasing the ND value.

Thus, the optimal red light therapy for weight loss and fat-burning is a combination of short red light and near-infrared light, using 630, 660, 810, 830, and 850nm wavelengths in synergy. 780 nm is another wavelength that has been linked to improved thyroid function, so adding it to the mix might give your treatment an extra boost.

Blue light will only reach cells very close to the skin’s surface. Because acne-causing bacteria can reside there, blue light can be helpful in clearing up acne, rosacea (a skin condition causing a patchy rash-like appearance on the face), and other minor skin problems.

A variable neutral density (ND) filter is a versatile tool used in photography and videography to control the amount of light entering the camera lens. It consists of two polarizing filters that are stacked together and can be rotated relative to each other. The construction and components of variable ND filters play a crucial role in their functionality.

Any results, however, will be less than those that could be accomplished with red light. Blue light is not capable of accessing your cells at a level deep enough to significantly impact deep tissue healing, pain relief, disease treatment, or anything that isn’t located just a few millimeters beneath your skin’s surface. Red light therapy, on the other hand, reaches deep into your body to jump-start its natural healing capabilities.

A variable neutral density (ND) filter is a versatile tool used in photography and videography to control the amount of light entering the camera lens. It consists of two polarizing filters that can be rotated independently, allowing the user to adjust the density of the filter and thus control the exposure.
