That’s what the Blue Light Cartel wants everyone to think.

Scientific Article? It looks more like a press release to me, probably from the university’s PR office.

Although the Phys.org article almost certainly was derived from something written by a PR person, there is a real scientific paper behind it:

http://dx.doi.org/10.1038/s41598-018-28254-8

When I looked at the paper, I rapidly found out why the PR person actually did perform a useful role in this case Smile

Press release based on a published scientific article.

This is what happens when your big, fat government grant to push man made global cooling/warming/change dries up and you still have to pay off the Range Rover.

Paraclesus was on the right track on this topic as with so many others when he argued, “Sola dosis facit venenum.”

The actual paper is about in vitro testing (eg – in a petri dish) that appears to be aimed at determining the chemical and biological processes by which blue light contributes age related macular degeneration.

Although well outside my expertise, it appears to be good research into the fundamentals of how the eye functions and why blue light exposure is correlated with long term adverse effects.

However, it does not examine what level of risk is correlated to given exposure levels, so it is a misrepresentation of this research to present it as an argument for avoiding all blue light exposure.

Well, I have had a couple of Blue Light Photodynamic Therapy for pre-cancerous lesions.
One on my face 2wks ago and yesterday on both forearms.

I’ve had innumerable burn-offs using liquid nitrogen to get rid of barnacles on my hands and face/neck. I worked in the field most of my life in sunny So-Cal and had a three wheel M-Cycle with which we toured pre-helmet laws. Fishing was the primary choice for vacation venues. Lots of sun…not so much sunscreen. I quit smoking in time to dodge that bullet, butt now I’m fighting this contender for my mortality.

The first facial treatment was like getting a suntan….sorta. Wiped my face with acetone,(now that is some serious oil remover), then she shook up a vial of $735 lotion that she applied all over my mug. Wait one hour, then activate the magic elixir with the blue light 3/4 enclosure around my head which attacks any cancerous/pre-cancerous lesions. I’ve had better days on the beach, butt it was only mildly prickly/itchy/burning.

The arm session was a bit more intense. She wiped the elixir from two vials on my forearms and I waited 2hrs this time. When she started the 15 min 40 sec treatment I knew this one was different. I truly expected my hands/arms to look like lobster claws. I endured the burn only by twitching/shaking and not wimping out with my wife right there. Displaying a bit of sun-poisoning, one forearm is like Popeye, the other like Olive Oyl.

The second day is much better. Not hurting at all, just some itch. I would definitely advise this over the ointment which produces lesions which take weeks sometime to heal. More like a bad sunburn. Just one more treatment on my face and one on my arms.

Anyway blue light is not all bad!

Always get annoyed by the contradictory articles.

Good luck chinooker with the treatment, that does not sound like a lot of fun, but I hope it works!

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)

More info from American Cancer Society on treatment of actinic keratosis which are considered pre-cancerous lesions.
https://www.cancer.org/treatment/treatments-and-side-effects/treatment-t...

My arms/hands are pretty much healed of the treatment and already look much improved with fresher looking skin and way fewer bumps and barnacles. My 2nd & last facial was last week and has peeled like my worst sunburn. My 2nd & last arm treatment is scheduled on the 24th. I recommend this over the Chemotherapy or Cryosurgery which can miss quite a few of the small ones which then show up later. This covers the whole area that the liquid is applied.

They say no exposure to sunlight for a few days. I knew better and I had my hat on and I just needed to run the riding mower up to the new shed our contractor is building so he could adjust the ramp for proper clearance for the cutting deck. Wow, I paid dearly for just a few minutes off side exposure to the early morning sunlight. Pay attention to their instructions!

I find it quite amusing to see people using his smartphone screens with “night modes” activated, makes screens look like CRAP. Big Smile

A slight screen temperature correction can be beneficial for those willing and able to do it. Related information: http://www.tannerhelland.com/4435/convert-temperature-rgb-algorithm-code/

Blue light wakes you up. Without it we would aways be somewhat tired.
