Red Light With Near Infrared Therapy

Our PlatinumLED Therapy Lights, Biomax LED Red Light Therapy (RLT) with Near Infrared (NIR) spectral output provides a multi-wavelength response for the most optimal spectrum possible.

R+ | NIR+ spectral output featuring the seven wavelengths of 480nm, 630nm, 660nm, 810nm, 830nm, 850nm and 1060nm.

Today, many manufacturers only offer two wavelengths:

  • the 660-nanometer (nm) red wavelength
  • the 850 nm near-infrared (NIR) wavelength.

The Outstanding Benefits of IRRLT

reproductive health

Several studies have indicated that low doses of red light cause an increase in sperm motility and overall fertilizing potential in several species1,2,3,4. By increasing sperm swimming speed in vitro, the likelihood of contact with the oocyte is increased. Therefore, low-level light exposure has the potential to improve fertility, particularly with respect to in-vitro fertilization (IVF).

Mental Health

If light therapy shows to be safe and effective in the reduction of depressive symptoms and improves insulin sensitivity, light therapy may be a valuable patient friendly addition to the currently available treatment strategies for major depression in T2D patients, assuming that improved insulin sensitivity may lead to improvements in glycaemic control, as measured by fasting glucose levels and HbA1c levels.

Skin Health

LLLT appears to have a wide range of applications of use in dermatology, especially in indications where stimulation of healing, reduction of inflammation, reduction of cell death and skin rejuvenation are required. The application of LLLT to disorders of pigmentation may work both ways by producing both repigmentation of vitiligo, and depigmentation of hyperpigmented lesions depending on the dosimetric parameters.

Eye Health

Research clearly shows that red light therapy has great potential for helping protect retinal cells from damage, reducing vision loss, reducing inflammation, and healing eye injuries. Red light appears to be especially effective in treating age-related ocular disorders such as macular degeneration and glaucoma.

Diabetic retinopathy results from abnormal levels of glucose in the retina of the eye. This can lead to the death of retinal ganglion cells, which are critical for vision. Animal studies have shown that red light therapy results in significant reduction of ganglion cell death, and reversal of diabetes-induced inflammation. During a 2016 study with rabbits, researchers from Iran discovered that low-level NIR light (810nm) reduced corneal inflammation caused from physical injury to the eyeball. In a 2010 study, researchers from Australia found that red light therapy was effective in preventing cell death, and also aided in restoring vision after optic nerve injury. Another promising finding was that red light protected cells in the vicinity of an optic nerve injury because of the cells’ close proximity to the injured area.

Leber hereditary optic neuropathy (LHON) is an inherited form of vision loss that is responsible for about 2% of all blindness. Although no study has conclusively shown that red light therapy is an effective treatment for this condition, it is known that increasing mitochondrial biogenesis (or, synthesis) may be an effective method for protecting retinal ganglion cells in patients with LHON. Several studies are currently in progress about the potential of red light to counteract the immediate consequences of mitochondrial failure.

A degenerative genetic disorder that breaks down cells in the retina, retinitis pigmentosa can lead to night blindness and loss of peripheral vision. Like other degenerative conditions, mitochondrial dysfunction and oxidative stress play an important role in the development of this debilitating disease.

AIn a 2012 study with rodents, researchers used red (670nm) and NIR (830nmA) light to treat the creatures’ eyes. The study revealed that red light treatments stimulated mitochondrial functioning, reduced oxidative stress, and prevented cell death, and this helped to preserve normal retinal function. From these promising results, the researchers determined that red light therapy can be an effective solution for the prevention and treatment of retinal diseases.

Studies on using red light therapy to treat eye conditions point to no more than two minutes per session every other day.

The terms Near Infrared (NIR), R+, NIR+, and Low-Level Laser Therapy (LLLT)—refer to different aspects of light therapy, particularly in the context of red and near-infrared light applications. Let’s break down these terms and concepts:

Near Infrared (NIR)

Near-infrared light refers to electromagnetic radiation with wavelengths that are longer than visible light but shorter than traditional infrared radiation. In the context of light therapy, NIR is often used for its potential therapeutic benefits, including improved cellular function and tissue repair.

R+ | NIR+ Spectrum

R+ (Red) | NIR+ (Near Infrared) spectrum indicates a combination of red and near-infrared wavelengths. In your case, it mentions five specific wavelengths: 630nm, 660nm, 810nm, 830nm, and 850nm. Each of these wavelengths may have different effects on biological tissues, and the combination is designed to provide a broad and potentially more effective spectrum for various therapeutic purposes.

Low-Level Laser Therapy (LLLT)

LLLT, also known as photobiomodulation (PBM), refers to the use of low-level lasers or light-emitting diodes (LEDs) to stimulate cellular function. LLLT typically utilizes red and near-infrared light in the range of 600nm to 1000nm. The idea is that these low-level doses of light can have positive effects on cells, tissues, and organs.

  • The key difference lies in the specific wavelengths used and how they are combined. The R+ | NIR+ spectrum you mentioned includes multiple wavelengths within the red and near-infrared range, while LLLT is a broader term encompassing various devices and protocols that use low-level light for therapeutic purposes.
  • The effectiveness of light therapy depends on factors such as wavelength, intensity, duration of exposure, and the specific condition being treated. Research is ongoing in this field, and the optimal parameters may vary depending on the desired outcomes
