Restore Visual Function through V20 Light Therapy
1, What is Light Therapy?
Using light as a healing tool may sound like a foreign concept, but is actually very common. For example, physicians use blue light therapy to treat infants born with jaundice and use white light to treat seasonaldepression. Dentists use light therapy to bond teeth. Our vision is based upon light interacting with photoreceptors in our retina. When light is absorbed by these cells, a photochemical reaction occurs converting light energy into electrical signals that are transmitted to the visual processing centers of the brain. Eye doctors may use specific frequencies and wavelengths of light to restore the optic nerve function and treat visual disorders. It works the same way as how the blue lights on our phones negatively affect our vision but in reverse. It increases blood flow and trains the brain to see correctly.
2. Benefits of Light Therapy:
This non-invasive light therapy device is eligible for all ages of patients, including young kids and seniors over 80 years old. It’s very effective for optic nerve damage caused by different reasons, such as glaucoma, ocular injury, ischemic optic neuropathy, optic neuritis, brain tumor;
Research showed that photobiomodulation at a wavelength of 670nm to be effective in preventing photoreceptor cell death in the retina. V20 light therapy also benefits retinal disorders like: retinitis pigmentosa, usher syndrome, Stargardt disease, macular degeneration, diabetic retinopathy and so on.
Benefits of V20 Light Therapy:
- Improve central vision acuity
- Expand peripheral vision
- Improve visual contrast and decrease light sensitivity
- Maintain the optic nerve cells’ function
- Improve energy levels and decrease eye strain
- Improve relaxation and sleep quality
3. How does it work?
This non-invasive photobiomodulation light treatment involves exposing the eyes to:
- low-level red light
- multispectral light
- syntonic light
4. Red Light Therapy：
We use 670 nm deep red light from Lambert diamond luminous body, which has been found to enhance retinal function by improving the efficiency of energy production in the mitochondria of retinal cells. By stimulating the activity of mitochondria, red light therapy can improve the production of adenosine triphosphate (ATP), the energy currency of cells. This increased energy production can improve the overall function of retinal cells, leading to improved vision.
Studies have also shown that this wavelength red light therapy can improve blood flow to the optic nerve, reduce oxidative stress, and promote the survival of retinal ganglion cells.There is evidence that deep red light of wavelength 670 nm is beneficial for protecting against loss of photoreceptors, however, normal infrared red light(700 nm or higher wavelength) might cause damage by heating.The keys to safe use are (1) getting a source with the right wavelength, (2) keeping usage to the recommendedtime, following the instructions.
How Red LightTherapy benefits: Glaucoma, Macular Degeneration, RP, Optic Nerve Atrophy, Ocular Injury, Eye Strain and Fatigue, Dry Eyes?
Glaucoma:is a progressive eye disease characterized by damage to the optic nerve, often associated with increased intraocular pressure. Red light therapy has been investigated as a potential adjunctive treatment for glaucoma. Studies have shown that red light therapy can improve blood flow to the optic nerve, reduce oxidative stress, and promote the survival of retinal ganglion cells. These findings suggest that red light therapy may have a role in managing glaucoma and restoring optic nerve function.
Macular Degeneration: Studies have shown that red light therapy can help slow the progression of AMD by promoting the growth and survival of retinal cells, reducing inflammation, and improving blood flow to the macula and preventing pressure and fluid buildup. The therapeutic effects of red light therapy on AMD have been demonstrated in both animal and human studies.
Retinitis Pigmentosa: This inherited disorder breaks down retinal cells and leads to night blindness, a loss of peripheral vision and can eventually lead to blindness. Researchers in 2012 examined the use of red light therapy in a mammal mode of RP, finding that 670 nm red light promoted mitochondrial integrity and function, prevented photoreceptor cell death, and prevented rods and cones death, and preserved retinal function. They even found the 670 nm red light exerted a robust retino-protective effect.
Optic Nerve Atrophy:Red light therapy has been found to enhance optic nerve function by improving the efficiency of energy production in the mitochondria of retinal cells. By stimulating the activity of mitochondria, red light therapy can improve the production of adenosine triphosphate (ATP), the energy currency of cells. This increased energy production can improve the overall function of the optic nerve cells, leading to improved vision.
Ocular Injury:Red light therapy has been widely studied for its wound-healing properties. When applied to the eye, red light therapy can accelerate the healing of corneal abrasions, surgical incisions, and other ocular injuries. It promotes the migration and proliferation of corneal epithelial cells, reduces inflammation, and enhances collagen synthesis. These effects can lead to faster healing and improved visual outcomes.
Eye strain and fatigue: In today’s digital era, prolonged exposure to screens and artificial lighting can lead to digital eye strain and fatigue. Red light therapy offers a potential solution to alleviate these symptoms. By reducing inflammation, increasing blood circulation, and promoting cellular energy production. Regular use of red lighttherapy may offer a natural and non-invasive approach to maintaining healthy visual function in the digital age.
Dry eye syndrome: is a common condition characterized by insufficient tear production or poor tear quality, leading to discomfort, redness, and blurred vision. Red light therapy has shown promise in alleviating the symptoms of dry eye syndrome by stimulating the production of tears, reducing inflammation, and improving the health of the ocular surface. Several studies have reported significant improvements in tear production and subjective symptoms in patients treated with red light therapy.
5. Multispectral Light Therapy:
Thistechnical solution is to use the specific frequencies and wavelengths(red-blue-green 3-color) light scintillation therapy device to irradiate the patient’s eyes.Research showed that blue, green andredlight exposure modifies the functional connectivity of neural networks and regulate neuro-chemical, hormonal and electrical balances. Regular stimulation with blue, green and red light activates several visual and non-visual brain regions.
The autonomic nervous system consists of the sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) nervous system. The three-colored lights used in multispectral light therapy stimulates the visual system which, in turn, changes the biochemistry of the brain.
Certain frequencies of colored light stimulate specific areas and affect different aspects of the nervous system:
- Red is lower energy and longer wavelength color. It stimulates the Sympathetic Nervous System to improve fusion and binocularity.
- Blue is higher energy and shorter wavelength color. It stimulates the Parasympathetic Nervous System. It can help to reduce adrenaline production, which then reduces anxiety and stress.
- Green is the middle frequency wavelength. It’s physiological stabilizer and detoxifier for chronic (long term) or degenerative health issues.
The study opens new avenues for better understanding the impact of multispectral light stimulation on vision-brain function and its use to treat visual dysfunction, depression symptoms, circadian rhythm disruption, migraine and memory or attention disorders.
6. Syntonic Light Therapy:
Syntonic light therapy is the use of specific frequencies and wavelengths of light to improve balance in the body’s regulatory centers. Doctors have been using syntonic therapy for over 80 years to treat amblyopia (lazy eye), strabismus (eye turn) and focusing/ convergence problems.
The retina is part of the brain. A large part of the brain is involved in vision and in coordinating vision with the other senses, including balance, hearing, and proprioception. The direct connection between the eye and the brain is the reason that light therapy through the visual system is so effective in changing brain function. The Autonomic Nervous System, also called the involuntary nervous system, is the part of the brain that enables us to do things automatically, without having to think about it, such as heart rate and breathing. It is divided into 2 parts, the Sympathetic Nervous System and the Parasympathetic Nervous System.
The Sympathetic Nervous system is for Fight or Flight. It ‘kicks in’ when someone is in a stressful situation, such as trying to stop a car on ice or when someone threatening is coming toward you. The following occurs:
- Your pupils dilate (get bigger) in order to bring in more light.
- Your eyes diverge to bring in more visual information.
- The lens in the eyes relaxes, so it doesn’t focus on things that close, like reading material.
- Your pulse goes up
- Your blood pressure and blood sugar levels go up.
The Parasympathetic Nervous system is for Rest and Digest. It controls how you are normally, in a non-stressful situation. That’s called Homeostasis.
- The pupils constrict (get smaller)
- You can focus on things at near, for example for reading or seeing the computer.
- Your eyes can point in toward reading material or a screen.
- Your blood pressure and blood sugar go down.
Light focuses onto the back part of the eye, the retina. It then goes to the optic nerve. and ultimately to the brain. The retina is actually brain tissue and that’s why light therapy is so effective.
This unique therapy benefits more than vision and can help with learning disorders, chronic headaches, or reducing the effects of brain injuries, stress, trauma and concussion. Previously, syntonic light therapy is done as a single, standalone treatment, but it is often combined with other types of vision therapy to reinforce and maintain long term benefits.Syntonic phototherapy is often used in conjunction with red light therapy and multispectral light therapy and works to speed up Home Vision Therapy.
