It's long been known that blue light is harmful to vision and a new study explains exactly why.
Blue light filters are popular on PC monitors and other displays as a way of preventing eye fatigue and reducing the risk of vision loss. Why exactly blue light is so harmful, however, apparently needed further research. A new study conducted by the optical chemistry research division at The University of Toledo sheds light on the situation.
The study, which was published in the journal Scientific Reports, explains that blue light exposure can actually poison eyeballs. In order to see, you need a continuous supply of retinal molecules, otherwise your photoreceptors are essentially useless. Blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in those all-important photoreceptor cells.
"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," Kasun Ratnayake, a PhD student researcher who contributed to the study, stated in a press release. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."
The death of photoreceptor cells is what's known as macular degeneration. Typically this happens with age, with more than two million new cases of age-related macular degeneration reported each year in the United States.
To study the effects of blue light, the researchers introduced retinal molecules to other cell types found in the body, including cancer cells, heart cells, and neurons. The cells died when exposed to a combination of blue light and retinal, but there was no effect when only introducing one or the other.
The good news in all this is that the research could lead to ways of preventing or treating the blue light's effects.
"We are being exposed to blue light continuously, and the eye's cornea and lens cannot block or reflect it," Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said. "It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop."
Unfortunately, avoiding blue light altogether is rather difficult. It emanates from PC monitors, cell phones, and other digital devices, and also from the sun. Dr. Karunarathne recommends wearing sunglasses that can filter blue light (and UV) when outside, and also avoiding staring at electronic screens in the dark.

Oh no. I stare at them in the dark too. Can't they fix the light problem?

And eaaier to see the screen with everything else dark I think. Shrug

And yeah, I miss my own little dark cinema.

Special glasses with blue light/UV filters? No as in, my eye sight has been deteriorating, therefore I wear glasses. I read a lot and use screens a lot. Both are bad for vision I think. I don't have perfect vision either. Oh well. I thought about eye surgery though. So could be a possibility to do one day. Only like 2000USD for me I think. Would you ever do eye surgery? Also you're almost a full member with 3 stars at 100 posts

Also you're almost a full member with 3 stars at 100 posts Probably not, I guess if anything I would try to recover some of my lost eyesight by just focusing more on far away objects and less of using devices. Also yay

ElizabethThe 3rd link is more detailed: "To protect your eyes from blue light, Karunarathne advises to wear sunglasses that can filter both UV and blue light outside and avoid looking at your cell phones or tablets in the dark."

A good article, but it's not exactly the right point. It's true that blue light is not good for the eyes of the ones which are daylight. I mean the ones of day people... Shortly, in the daylight the colors of green and red are the most of the colors, while at night our eyes are needed to be accommodated. Nightwatchers and the hunters have blue sensor eyes, because they use it for their hunt. The sum: blue colors can be harmful as something that leads us to not usual condition of using our eyes. The more we're staring at blue, the more nightwatchers people we become. But, actually, it is my own opinion. I can't deny all those good and detailed researches.

It's my favorite color You're not alone! I'm glad that your favorite color is blue (I'm sorry that I didn't ask you before about it). It was my favorite color in my childhood. I liked to draw with blue markers in my drawing-book. Blue seemed to me more loneliness and quiet - I was a quiet child. I wouldn't say that I was an introvert, but I prefer loneliness to 'companies' (little bunches of little children). Because of this reason I didn't like any holidays. There are noisy always. When I was a teenager my favorite color became red. But sometimes I like to buy something which colors is blue. And, hey, don't be upset! Blue that is surrounded by another colors is not dangerous. Only blue and blue only is dangerous. Or too many blue is able to be dangerous too. It's dangerous if your eyes are needed to accommodate to blue really hard with wasting many energy.
