Blue light (425-495nm) is potentially harmful to humans, inhibiting energy production in our cells, and is especially harmful to our eyes.
This can manifest in the eyes over time as poor general vision, especially nightime or low brightness vision.
In fact, blue light is well established in the scientific literature as a leading contributor to age-related macular degeneration.
Sailors throughout modern history are well known to have a higher rate of cataracts due to glittering sunlight being reflected on the oceans.
Sources of blue light
This harmful light comes from any source of direct blue or wider spectrum white light, including:
- midday sun
- smartphone screens
- tv screens
- street lighting
- car lights
- household technology
- and more

I always wondered what you looked like, Joe! (It is you, isn’t it?)
Just working my way through all the comments in your old blogs – very worthwhile. Any new blogs coming up?
Are you following the photobiomodulation Facebook page?
Not me unfortunately!
There is a new blog post coming up about red light for eyesight.
I am indeed following that page.
What about studies that have shown blue light to have benefits for acne?
What about studies that have shown X-rays help to reduce acne?
What about studies that have shown starvation helps to reduce acne?
There’s various things you can do that will reduce acne by sterilising or reducing sebum production and so on. The question is just whether those short term benefits to reduced acne are worth to long term potential harms.
We’d all agree that using x-rays on your face to reduce acne is a bad idea – it works for that, but it a bad idea because of long term damage/risks. I would say that blue light treatment is the same sort of thing. In fact, blue light is aging your skin and weakening it. You’re trading acne for looking older. The skin is also harmed in the process and the acne is more likely to return in the long term anyway. It’s a very shortsighted and uneducated approach to acne treatment, just as X-rays were when they were used for acne in the past.
