Red Light Therapy for Eyes: Improving Your Optical Health

Red Light Therapy for Eyes is a non-invasive treatment that utilizes low-level red light wavelengths to enhance optical health and improve vision. The therapy works by penetrating the layers of the skin and reaching the cells of the retina, stimulating cellular energy production and promoting blood circulation.

This process can lead to various benefits, including reduced eye strain, improved visual acuity, enhanced color perception, and relief from dryness or irritation. Red Light Therapy is a safe and effective method for improving optical health; however, it is essential to avoid direct exposure to the light source to prevent any potential adverse effects.

Red Light Therapy for Eyes Health

The eyes are possibly the most delicate and valuable components of our physiology. Our conscious experience heavily depends on visual perception, which is vital to our daily activities. The human eyes are particularly responsive to light, capable of distinguishing up to 10 million distinct hues, and can sense light within the 400nm to 700nm wavelength range.

What can Red Light Therapy Help with?

Red light therapy / Phototherapy can be beneficial for various eye conditions such as age-related macular degeneration, glaucoma, diabetic retinopathy, and dry eye syndrome. It can also help to improve visual acuity, reduce eye fatigue and strain, and promote overall optical health.

Many studies indicating advantageous outcomes rely on LEDs as the light origin, mainly with a wavelength of 670nm (red). However, the effects of light intensity and duration of exposure cannot be disregarded, as they also play a crucial role.

How does red light help vision?

Believe it or not, the secret lies in the mitochondria! Mitochondria are responsible for producing energy for cells, and red light therapy for eyes improves their ability to do so. The eyes require a lot of energy, as they have the highest metabolic requirements of any tissue in the body. As a result, they have a high concentration of mitochondria. By improving the function of the mitochondria, red light therapy can potentially restore the eyes and promote optical health. Plus, recent research has shown that mitochondrial dysfunction is linked to degeneration of the eyes and retina. So, let there be red light for healthy eyes!

Best wavelength of light

Of all the types of visible red light, 670nm is extensively studied for treating eye-related issues. Additionally, 630nm, 780nm, 810nm, and 830nm are also effective in yielding favorable outcomes. It is worth noting that laser and LED red lights can be used on any part of the body except the eyes. Lasers should not be used for eye light therapy.

Power density & dose

Nearly all red light that enters the eye is transmitted with a rate of over 95%, including near infrared light, as well as blue, green, and yellow light. Thus, the eye needs only the same type of treatment as the skin due to its high permeability to red light. Research has shown that treatments with a power density of approximately 50mW/cm2 and doses of 10J/cm2 or less are sufficient.

The science

The science behind red light therapy for eyes health is rooted in the functioning of mitochondria. Mitochondria are responsible for producing energy for cells, and the eyes require a lot of energy due to their high metabolic requirements. As a result, they have a high concentration of mitochondria and can reduce the aging process.

Red light therapy, also known as phototherapy, improves the function of mitochondria by enhancing their ability to produce energy. This, in turn, can potentially restore the eyes and promote optical health. Recent research has also shown that mitochondrial dysfunction is linked to degeneration of the eyes and retina.

Studies have shown that red light therapy can be beneficial for various eye conditions such as age-related macular degeneration, glaucoma, diabetic retinopathy, and dry eye syndrome. It can also help to improve visual acuity, reduce eye fatigue and strain, and promote overall optical health.

The most extensively studied wavelength of visible red light for treating eye-related issues is 670nm. Other effective wavelengths include 630nm, 780nm, 810nm, and 830nm. However, it is important to note that lasers should not be used for eye light therapy.

How to use red light therapy?

Using red light therapy for eyes health is a simple process that can be done in the comfort of your own home. Here’s how to use it:

  1. Purchase a red light therapy device that emits light in the 670nm to 830nm deep red light wavelength range. Make sure the device is specifically designed for eye therapy.
  2. Sit or stand in front of the device, keeping a distance of approximately 6-12 inches from your eyes.
  3. Close your eyes and turn on the device, allowing the red light to penetrate through your closed eyelids.
  4. Set a timer for the recommended duration of exposure, which is typically between 3 minutes to 20 minutes.
  5. Relax during the session, taking deep breaths and allowing the red light to work its magic on your eyes.
  6. After the session is complete, turn off the device and take a few moments to rest before opening your eyes.
  7. Repeat the process daily or as recommended by your eye doctor or healthcare professional.

Remember to always follow the recommended guidelines for duration and intensity of exposure to avoid any potential side effects. With consistent use, red light therapy foe eyes can potentially improve your visual acuity, reduce eye strain and fatigue, and promote overall optical health.

Harmful light for eyes

Blue, violet, and UV light wavelengths (200nm-480nm) are harmful to the eyes, as they are linked to retinal damage, corneal damage, and damage to the lens, humor, and optic nerve. So if using blue light always wear eye protection as it can lead to vision loss

This consists of blue light that is emitted directly, as well as blue light that is present in white lights like LED bulbs used in homes or on streets or on computer or phone screens. White lights that are bright and have a high colour temperature (3000k+) contain a significant amount of blue light and can have adverse effects on eye health.

The reflection of midday sunlight on water is a source of high blue light that can harm the eyes if exposed to it for extended periods. However, the earth’s atmosphere scatters blue light to some degree, which is known as “rayleigh scattering,” and provides some protection. Nevertheless, midday sunlight and sunlight seen by astronauts in space still emit a significant amount of blue light.

Sunlight reflecting off bodies of water appears bluer compared to red because water absorbs more red light. However, the reflected sunlight is not the only harmful factor as UV light can also cause eye damage, known as ‘surfer’s eye’. Those who spend time outdoors like hikers, hunters, and sailors are at risk of developing this condition. Traditional sailors, including navy officers and pirates, often suffered from vision issues due to prolonged exposure to sea-sunlight reflections and poor nutrition.

The eyes can be damaged by far infrared wavelengths and heat in general, just like other cells in the body. When cells exceed 46°C / 115°F, functional harm can occur.
