What role does blue light play in helping the body fight disease?
2.3. Summary. Blue light can be sensed by numerous bacteria and can induce physiological responses elicited by the blue light receptors. As a result of this, blue light can regulate bacterial motility, suppress biofilm formation, and subsequently potentiate light inactivation of bacteria.
What wavelength is blue light for acne?
Introduction. Blue light acne treatment is a non-invasive procedure that uses light in the blue wavelength range of 405-420 nm to kill the Propionobacterium acnes or P. acnes bacteria in skin.
Does blue light reduce pores?
For those who are hoping to reduce acne or make pores appear smaller, Skotnicki recommends blue light therapy. This is because the light may help shrink your oil glands, which in turn can reduce the oil production in your skin.
Is blue light a radiation?

What wavelength of blue light is most damaging to the retina?
between 415 and 455 nm A wavelength between 300 and 400 nm can penetrate the cornea and be absorbed by the iris or the pupil. High energy short wave blue light between 415 and 455 nm is the most harmful. Direct penetration of crystals into the retina causes irreversible photochemical retinal damage[1].
Are Bluelight glasses worth it?
According to the American Macular Degeneration Foundation (AMDF), there’s no evidence that blue light can damage the eye, and therefore any claims that glasses offer protection against retina damage or eye conditions like macular degeneration aren’t accurate.
Are blue light glasses scientifically proven?
ROSENFIELD: Both of the studies actually found that the blue-blocking filters have no effect, no significant effect on digital eye strain. This didn’t really come as a major surprise to us because there really is no mechanism whereby the blue light should be causing digital eye strain.
Does UV light help immune system?
UV radiation suppresses the immune system in multiple ways. It inhibits antigen presentation, stimulates the release of immunosuppressive cytokines and induces the generation of lymphocytes of the regulatory subtype. The major molecular target for UV-induced immunosuppression is UV-induced DNA damage.
Can blue light make acne worse?
The wavelength of blue light has an antimicrobial effect, making it effective at killing several types of bacteria that can collect in your pores and oil glands and cause breakouts. In one study, people with acne who were treated for five weeks with blue light therapy saw improvement in 77 percent of cases .
What wavelength is best for acne?
Blue light is the most effective light to target Propionibacterium acnes (specifically at wavelengths of 407-420 nm). However, many devices are utilizing red light because it has a purported anti-inflammatory effect and penetrates deeper into the skin (Dermatol. Ther.
Does blue light work on cystic acne?
A: I recommend the blue light treatment to my acne patients with red pimples (inflammatory acne). In my clinical trial with an at-home use blue light (Silk’n Blue, Home Skinovations Inc.), my patients had good results treating not only mild, but moderate and even severe, cystic or scarring acne.
What does your face look like after blue light treatment?
Immediately following treatment, the area may be red, swollen, tender, and mildly bruised or blistered, especially when medication has been applied to the skin. The treated area may crust over or peel, but this is considered normal. Most people heal within 7 days, and the crusting resolves within 3 to 14 days.
Does blue light therapy cause hyperpigmentation?
Blue light also induces hyperpigmentation that can lead to sunspots or dark spots by affects the production of melanin in your skin cells — the dark pigment responsible for tanning your skin in response to sunlight exposure.
How often should I use LED light therapy at home?
You’ll need to go back once a week for up to 10 weeks, then only once every few months. At-home LED devices can be used at your convenience without having to go to any appointments.
Do UV glasses block blue light?
There are anti-blinding qualities to Blue Light Glasses, whereas UV protection lenses, on the other hand, do not impede the blocking of blue light.
Is Blue light worse than UV light?
You know it as ultraviolet light, the wavelengths between 290nm and 380nm are (UVB/A) and 380nm to 500nm are (blue light). Because blue light has a very short wavelength, it produces a higher amount of energy than the other wavelengths of the visible spectrum.
Is blue light more harmful than UV?
Blue light has very short, high-energy waves. In fact, they’re only slightly longer and less powerful than ultraviolet (UV) waves (which are too short for people to see with the naked eye). Health experts have warned against the harmful effects of UV rays, which can damage your skin and your eyes.
Are Bluelight glasses bad for your eyes?
Can blue light blocking glasses damage your eyes? No. Blue light blocking glasses don’t damage your eyes. In fact, blue light glasses shield your eyes from the damaging effects of blue light, which is the type of light that’s emitted from electronic devices, like tablets, smartphones and laptops.
Can I wear blue light blocking glasses all day?

How do I block the blue light on my computer?
Go to Settings (or Windows key + I), click on System, and, under Display, click to turn Night light on or off. You can also customize the color temperature or schedule by clicking “Night light settings.”
How can you tell if blue light glasses work?
A good test at home is to pop your computer glasses on and see what colour the light is that is reflecting off the lenses. If it’s blue light that’s reflecting off them then you know they are filtering some blue light.
How damaging is Bluelight?
There’s growing medical evidence that blue light exposure may cause permanent eye damage. This contributes to the destruction of the cells in the center of the retina and play a role in causing age-related macular degeneration, which can lead to vision loss. The risk is higher in females than males.
How do you know if blue light glasses work?
In order to be functional in filtering blue light, your blue light glasses should filter down at least 30% of blue light across the entire blue light range. … If the reflection is purple, that’s an indication that they are not filtering blue light effectively. If it’s blue, they are filtering at least some of it.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
