The screens are destroying your eyes. Now we know how!

Our mobile phones have become our favorite phones. We have not left the morning until the last moments before sleep, but the blue light emitted by this and our other digital devices may not be our trusted friend.

The story of discoveries continues daily about the damaging effects of blue light, causing disturbances in the rhythms of our biological clock and consequent pain with insomnia and sleeping problems. Physicians also drew attention to the relationship between these devices and eye problems, ranging from daily eye strain to blue water (glaucoma) to macular degeneration.

In a new report, mentioning the popular historical space in this area shows how blue screens can ruin the eyes and what do we do about it?

Danger

People see a certain range of light, from red to violet. Smaller wavelengths appear blue, while farther they appear red. What we see as white – whether it comes from sunlight or a screen – actually contains almost all the colors in the spectrum.

The visible light extends between the red and the purple, the source of the image: Wikipedia

In a recent publication in Naturefort magazine, researchers at Toledo University began to analyze how irreparable damage to the cells of the eye could be due to a prolonged or prolonged exposure to short beams of 445 nm, called blue light. The results can have serious consequences for consumer technology in general.

The professor of chemistry and author of the study "Agith Karonarathny" looks like the optic receptors of car and retinal fuel. Explain in detail: "When the cells of the eye in the blue light are directed directly to the lab – they theoretically resemble what happens when we look at our telephone screens and computers – Chemical reaction to the retinal molecules in the eye. Blue light causes retinal oxidation, creating toxic chemical formulas

The result, according to "Karonarathny":

The retina provides the energy of this particular light area by killing cells that receive light; these cells are not regenerated if they are destroyed.

If the retina is a fuel, blue light is dangerous

These results do not mean that catastrophic damage to sight has been resolved. But the experiment shows how blue light can kill cells that receive light. Blue light has the ability to kill enough of them to cause macular degeneration, a debilitating illness that makes vision fog or even destroys.

Blue addiction

The report notes that blue light naturally exists in the sunlight, among other forms of visible light, ultraviolet radiation and infrared radiation. But as Caronarathini points out, we often do not look at the sun and most of us learn in childhood that it hurts in the eyes. However, digital devices have a bigger alarm. The average American spends about 11 hours a day on some screens, according to a Nielsen 2016 poll. So far, as you read these words, you often experience blue light.

When looking directly at the screens – especially in the dark – we show the light in a very small area within the bulb. Caronarathini explains the dangerous effect of this from another analogy:

The intensity of light from the device may increase exponentially. When you move a magnifying glass to the sunlight, you see the intensity of the light in the focus, you can burn something inside it.

Orange is the new blue

User experience designers criticize our dependence on blue light according to the report. Among them is Amber Case, a writer of Quiet Technology, who writes in one of her stories that blue light has become the color of the future, partly due to cinematographic films such as the Blade Runner in 1982. Moving from Lamps Illuminated in Lights LED high performance and high power, another boost for the spread of blue light. Watch bag:

If our folk culture leads us to a blue enlightened reality that hurts us too, it can also help us get to the new aesthetic of orange.

He notes that the army continues to use red or orange light on many of its facades, including those located in control rooms and cabins, adding: "The effect of these colors is minimal, so it is ideal for night shifts" and eliminates "optical abnormalities" Blue light – the sense of extreme illumination of the screen light in the dark – is dangerous in many cases.

Any solutions?

The report lists some of the most useful technologies available today. For example, Apple offers a night-time option on its phones and devices, allowing users to filter the screens from the blue to appear at sunset. There are also various products to control the flow of blue light into the iris, including desktop screens. There are also blue glasses filters for video game enthusiasts. But, the more devastating the damage caused by our vision, consumers are demanding more and more radical changes.

As the new generation grows, the question will be: Did the damage happen?

"It will take time to see what damage these devices can do over time and if the damage happens, how much is it?" Caronarathini plans to concentrate on data collection from now on. When the new generation grows, the question will be: Did the damage happen? "But now, with the biochemical part of the effect of blue light, Caronarathini looks at new innovations:" Who knows! "One day we can develop eye drops you use when you know that you have been exposed to intense light from which some droplets to reduce damage.
