Since Apple added night mode to the iPhone, every night at 10 o'clock, night view mode will make my phone screen turn yellow. When I see a light yellow phone, I will subconsciously tell myself: to start preparing Sleeping, you will enter the state of staying up late if you don't sleep.
Many studies have shown that using mobile phones, iPads and other electronic devices before going to bed can affect sleep quality, induce sleep disorders such as insomnia, and the culprit is blue light.
Blue light refers to high-energy visible light, blue-violet visible light with a wavelength of 400-500 nm. The human body clock is particularly sensitive to blue light in this band. Studies have shown that people exposed to blue light for more than two hours before going to bed, the nervous system that controls the circadian rhythm in the brain will be disturbed, thus affecting the secretion of melatonin.
The decrease in melatonin secretion caused by blue light, in addition to the effects on the retina and sleep, is also indicated by research, which may induce three types of cancer such as breast cancer.
The research paper that first pointed out the hazard of blue light was released in 2001. But since then, until now, the display of electronic devices with blue tones has not decreased. On the contrary, the continuous technology products still use blue as the main color of the products.
From the preset UI main color in the new mobile phone, to the display screen of the service robot, to the dashboard and the central control panel in the car, these products that emit faint blue light have surrounded us. LEDs (light-emitting diodes), energy-saving lamps, and xenon lamps, which are becoming more and more popular, have more blue light than traditional light bulbs.
Blu-ray is not the best choice in an information-intensive environment
Nowadays people process a lot of information from electronic devices every day, which may be a bit like the intelligence officer on the complex console in the twentieth century battlefield. But in the same electronic device usage scenario that handles intensive information, intelligence officials and users of ordinary technology products have very different details.
We hold mobile phones and iPads, which are generally surrounded by blue light and white light. In military cockpits, submarines and other military-grade consoles, the interface of these terminals is mainly dark red or dark orange.
This is because the human eye sees visible light with a wavelength of 605 nm, that is, orange-red, the eyes are most comfortable. This is related to the retinal rod cells (Rod) and retina cone cells (Cone) responsible for photosensitivity in the human retina.
▲ Retinal rod cells (Rod) and retina cone cells (Cone)
Retinal rod cells are more sensitive to moving objects and least sensitive to color, especially orange-red. Retinal cone cells are sensitive to a variety of colors, among which are most sensitive to the identification of orange-red.
Therefore, in an environment where it is necessary to concentrate on the surrounding environment and need to process electronic device information, such as a night driving environment, the use of orange-red dashboard is the most comfortable and safe.
Friends who drive at night may have had such an experience. When looking forward to the road and looking down and down between the mobile phone and the central control screen, there will always be a moment when the eyes are black and nothing can be seen.
This is because when driving at night, observing the road ahead, the eyes will produce longer and more intense visual afterimages. However, when switching to a dashboard, a central control panel, etc., a brighter block of high-energy light is seen, which also leaves a visual residual image in the dark.
There are relatively extreme brightness contrasts and different visual afterimages before and after switching, which causes visual discomfort, which is "glare". The visual fatigue caused by glare is the cause of many nighttime car accidents.
BMW's ancestral orange-red dashboard light has been in use since the 1970s until this year. The reason for using this color is mainly because BMW used to make cars for the military in the early years.
Science fiction movies bring blue light to the stage
Since blue-violet light is so easy to cause visual fatigue, why are so many technology products still in use? Because in the post-Cold War movie of the United States, the high-tech of the future world appears on the screen in blue tones.

Orange represents the electronic display of the war era, and blue is the complementary color of orange. The widespread use of blue also means the transformation of the old era to the new era after the end of the Cold War.
▲ Image from: 2001: Space Roaming
In the late 1960s, the film "2001: Space Roaming" and "Star Trek" described the future world that people imagined at the time. The main color of the spaceship bridge in the movie was still orange or Orange.

However, in 1982, "The Blade Runner" was released after the Cold War. As the originator of the science fiction film, its use of yellow and blue tones quickly influenced artists, designers and advertisers at that time.

In the "Blade Runner", director Ridley Scott painted to the public a future world that they believe to be credible. The technological element of the future world, the main color is blue. In the dark, the blue light that appeared in the display became the "future technology" that people recognized at the time.
At the same time, blue is the color of the sky and the ocean, but among the plants and animals in nature, blue is a relatively scarce color, so it also carries a sense of mystery.
▲ Blue screen in science fiction movies
Later, the science and technology products in science fiction movies, the imagination of the imitators of the predecessors braved the blue light, and also affected the people who later produced and designed cutting-edge technology products. For example, the early blue computer screen, the blue of the hyperlink in the network, the blue of Windows, the blue of Intel, and then the technology giants such as Facebook and Twitter have a preference for blue.
▲ This blue screen is also a terrible problem
Regrettably, these blue light emitted from electronic devices are causing trouble for people who are increasingly obsessed with technology products.
What can we do with Blu-ray?
Although artificial blue light surrounds humans, the sun is still the largest source of blue light for us. According to Zeiss China's data, the amount of blue light that the eye receives for an hour outside the normal cloudy day is 30 times that of a computer sitting in front of the screen for an hour.
However, as human nighttime increases, electronic devices and LEDs increase in light sources, the time and dose of blue light received by the human eye has greatly increased.
Popular culture used to make Blu-ray a symbolic product of electronic product design, so popular culture can also bring the function of orange-red light back to the public. But the re-education of the pop culture of "letting orange-red light replace blue-violet light" has not yet arrived.
Devices such as iOS and Android have begun to popularize night mode, and it does not make people aware of the harm of blue light to the human body, nor can it prevent people from putting down their mobile phones to go to bed early.
In order to minimize the impact of blue on daily life, perhaps we can try these few tricks first:
Use night mode on mobile phones and computer equipment, and use less sleep at night.
Wear glasses that protect the eyes while driving outdoors and while driving
I have to stare at the screen before going to bed.
Don't mess with anti-Blu-ray mobile phone film, inferior film may make your eyes more tired.
