Photobiomodulation

Photobiomodulation is the use of light to influence cellular function, also known as low level light therapy.

How does the Arunalight work?

The Arunalight looks like a pair of sunglasses and is worn for 3 minutes every other day at home. A total of 26 red lights are strategically placed to gently treat the eyes and surrounding skin. With a lifespan for thousands of uses, these medical grade light diodes offer a superior defined and optimized wavelength (670nm).

What is the Arunalight used for?

Photobiomodulation has shown great promise in treating various retinal conditions. A study by Behlahbib et al. (2023) suggests that photobiomodulation may offer a viable therapeutic option for age-related macular degeneration, potentially slowing the progression of the disease. Additionally, another study demonstrated a significant reduction in the onset of new geographic atrophy in patients receiving photobiomodulation treatment. 

Additional studies show promising results for photobiomodulation in treating diabetic retinopathy, including reducing macular edema and improving visual acuity. In glaucoma, PBM may help enhance retinal nerve fiber layer thickness and lower intraocular pressure. For dry eye syndrome, it has the potential to increase tear production and improve meibomian gland function. PBM also shows promise in reducing inflammation in uveitis and other inflammatory ocular conditions. While most studies to date have been conducted in animal models, the findings are promising, and while applications to humans are still limited, they remain a potential avenue for future exploration.

Some studies involving Cellular Mechanisms activated with Photobiomodulation at 670nm

Oxidative Stress Reduction in Diabetic Retinopathy

This wavelength ameliorates diabetic retinopathy by reducing oxidative stress and cell death, offering a potential therapeutic approach for diabetic retinopathy management.

Müller Cell-Mediated Retinal Inflammation Reduction

670 nm light reduces Müller cell-mediated
retinal inflammation, which could be beneficial in treating retinal degenerations associated with inflammation.

Improved Retinal Function in Aging

670 nm light can significantly improve aged retinal function, potentially providing benefits in age-related visual impairments.

Optic Nerve Protection

NIR-LED photobiomodulation accelerates wound healing and attenuates degeneration in the injured optic nerve, suggesting its potential use in optic nerve injuries or
degenerative diseases.

Photoreceptor Neuroprotection

The light therapy increases the spare respiratory capacity of mitochondria in photoreceptor-like cells, which can prevent photoreceptor cell death in conditions
like age-related macular degeneration.

Inhibition of Diabetic Retinopathy Progression

The light inhibits the functional and histopathologic features of early diabetic retinopathy, likely mediated via multiple mechanisms, offering a potential
therapeutic approach for diabetic retinopathy management.

Cell Viability Improvement

670 nm LED irradiation enhances cell viability in hypoxic rhesus monkey choroid-retinal cells.

Mitochondrial Function Augmentation

Red light promotes mitochondrial function and stimulates antioxidant pathways, protecting photoreceptors in retinal dystrophy and potentially aiding in diseases like retinitis pigmentosa.

Reduction in Retinal Inflammation

The light improves mitochondrial metabolism, reducing retinal inflammation, which could be useful in managing inflammatory retinal diseases.

Therapy for Large Soft Drusen

PBM may provide a valid therapeutic option for large soft drusen and drusenoid pigment epithelial detachment age-related macular degeneration and may potentially slow the natural course of the disease.

Improved clinical and anatomical outcomes for Dry AMD

Improvements in clinical and anatomical endpoints following PBM treatment suggest disease-modifying effects.

Improvement in Scotopic Thresholds

In healthy ageing, rod function and scotopic thresholds appear to improve by 12 months with 670 nm light.

What is Photobiomodulation?

Photobiomodulation is a form of light therapy that uses red light to stimulate mitochondria in our cells. Mitochondria, often called the "powerhouses" of the cell, are responsible for energy production. They contain chromophores, which are molecules that absorb specific wavelengths of light. When red and near-infrared light is applied, these chromophores absorb the light, helping the mitochondria break down nutrients and convert them into ATP (adenosine triphosphate), the primary energy currency of our cells.

"Modulating" means to adjust or control something. In this context, it refers to enhancing how mitochondria function and how much energy they produce. Research shows that specific wavelengths of red and near-infrared light can boost ATP production, leading to increased energy transport within cells and promoting cellular proliferation—the process by which cells grow and divide.


Using red light on mitochondria is analogous to giving them a boost or a tune-up, helping them work more efficiently. This therapy can be beneficial for healing, reducing inflammation, and improving overall cell health.

Mitochondria
Retina Photo

Findings in vitro and in vivo support the hypothesis that photobiomodulation (PBM) enhances mitochondrial function and activates antioxidant pathways in the neural retina, protecting against retinal degeneration. PBM offers a non-invasive alternative to traditional treatments, harnessing the body's natural repair mechanisms to prevent and treat retinal dystrophies and degenerative diseases.

Recent data indicate that 670nm red light significantly protects the retina from light-induced damage, suggesting its potential to mitigate the harmful effects of bright light exposure. This non-invasive approach shows promise for treating retinal degenerative disorders and ocular inflammatory diseases.

The effectiveness of PBM depends on factors such as light source, wavelength, energy density, light pulse structure, and application duration.
