It’s Official: Blue Light Is Killing Our Eyes

The Alt Media has been pursuing this subject for a long time and the evidence has been steadily mounting. Here’s a new report from the mainstream via Popular Science:

 

Screens are killing your eyeballs, and now we know how

The “blue screen of death” is taking on a whole new meaning.

By Eleanor Cummins August 11, 2018

Blue light’s rap sheet is growing ever longer. Researchers have connected the high-energy visible light, which emanates from both the sun and your cell phone (and just about every other digital device in our hands and on our bedside tables), to disruptions in the body’s circadian rhythms. And physicians have drawn attention to the relationship between our favorite devices and eye problems, ranging from everyday eye strain to glaucoma.

Humans can see a thin spectrum of light, ranging from red to violet. Shorter wavelengths appear blue, while the longer ones appear red. What appears as white light, whether it’s from sunlight or screen time, actually includes almost every color in the spectrum. In a recent paper published in the journal Scientific Reports, researchers at the University of Toledo have begun to parse the process by which close or prolonged exposure to the 445 nanometer shortwave called “blue light” can trigger irreversible damage in eye cells. The results could have profound consequences for consumer technology.

Visible light runs from red to violet. On the far ends are infrared and ultraviolet, which both range outside human vision.

“Photoreceptors are like the vehicle. Retinal is the gas,” says study author and chemistry professor Ajith Karunarathne. In the lab, when cells from the eye were exposed to blue light directly—in theory, mimicking what happens when we stare at our phone or computer screens—the high-intensity waves trigger a chemical reaction in the retinal molecules in the eye. The blue light causes the retinal to oxidize, creating “toxic chemical species,” according to Karunarathne. The retinal, energized by this particular band of light, kills the photoreceptor cells, which do not grow back once they are damaged. If retinal is the gas, Karunarathne says, then blue light is a dangerous spark.
Catastrophic damage to your vision is hardly guaranteed. But the experiment shows that blue light can kill photoreceptor cells. Murdering enough of them can lead to macular degeneration, an incurable disease that blurs or even eliminates vision….
