The screens destroy your eyes .. Now we know how!


Our mobile phones have become our favorite devices. We have hardly left since early in the morning until the last moment before bedtime, but the blue light emitted from it and from our other digital devices may not be our trusted friend.

The story of discoveries goes on the harmful effects of blue light day after day, causing disturbances in the rhythms of our biological watches and subsequent suffering with insomnia and sleep problems. Doctors also noted the relationship between these devices and eye problems, ranging from daily eye stress to blue water (glaucoma) to macular degeneration.

In a new report, the report from the popular science website in this field shows how blue screens can destroy the eyes and what do we do about it?


People see a certain spectrum of light, from red to violet. The shorter wavelengths are blue, while the longest ones appear red. What we see as a white color – whether it comes from sunlight or from a screen – actually contains almost all colors in the spectrum.

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

The professor of chemistry and authors of the study "Agith Karonarathny" looks like the optical receptors in the car and retinal fuel. Explain in detail: "When the cells of the eyes to the blue light directly in the laboratory – theoretically simulated what happens when we look at our phone monitors and computers – Chemical reaction in retinal molecules in the eye. Blue light causes retinal oxidation, which creates toxic chemical types.

The result, according to «Karonarathny»:

Retinal provides energy from this specific light region, kills cells that receive light, these cells do not regenerate if destroyed.

If the retina is fuel, the blue light is dangerous.

These results do not mean that the catastrophic visual impairments are solved. But the experiment shows how blue light can kill cells that get light. Blue light has the ability to kill them sufficiently to cause macular degeneration, a weakening disease that makes the vision foggy or destroyed.

Blue addiction

The report notes that blue light is naturally present in sunlight, including visible light, ultraviolet and infrared radiation. But as Caronarathini points out, we do not often starve at the sun, and most of us learn during childhood that it hurts the eyes. However, digital devices have greater alarms. The average US spend about 11 hours a day on some screens, according to a Nielsen 2016 survey. As long as you read these words, you often experience blue light.

When we look directly at the screens – especially in the dark – we point the light on a very small area of ​​the eyelid. Caronarathini explains the dangerous effect of this by another analogy:

The intensity of the light from the device can be increased exponentially. When wearing a magnifying glass in the sunlight, you see the intensity of the light in focus, you can burn something in it.

Orange is the new blue

User experience designers criticize our dependence on blue light according to the report. Among them is Amber Case, author of Quiet Technology, who in one of her posts documents how blue light became future color, partly due to films like Blade Runner 1982. The environmentally-driven transition from lamps Glowing to high-efficiency LEDs and high watt, another driving force against the spread of blue light. Track Bag:

If popular culture drives us into a blue enlightened reality that hurts a lot, it can also help us achieve a new orange ethic.

She notes that the army still uses red or orange light for many of its façades, including those in the control rooms and cabins, adding: "The effect of these colors is minimal so it's ideal for night shift" and eliminates "visual deviations" Blue light – the feeling of extreme brightness in the light of the screen in the dark – is risky in many cases.

Any solutions?

The report shows some of the most useful technologies currently available. For example, Apple offers a "night mode" option on its phones and devices, allowing users to filter screens from blue to appear at sunset. Several products are also available to control the flow of blue light to iris, including desktop screens. There are also blue-screen goggles for video game enthusiasts. But the more blue light damage and damage that causes our vision, consumers demand more and more radical changes.

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

"It will take time to see what damage these devices can do over time, and if the damage happens, how much does it cost?" Caronarathini plans to focus on collecting data from here. As the new generation grows, the question will be: Damaged damage? "But now, with the biochemical trace of the effect of blue light, Caronarathini sees new innovations:" Who knows! We can one day develop drips of the eye you use when you know that you have been exposed to intense light, from which some drops take to reduce the damage.
