More people spend time in front of computers. Many jobs can be handled with a computer. Will you leave your computer away from work? Not so. Another computer is waiting for us. People sit or stand with their heads down and stare into the smartphone. The moment we are free from the display is the time we slept.

The convenience of digital devices is hard to deny. The problem is that it creates other inconveniences. Because of the use of digital devices, many people's postures have collapsed, and even now the neck and waist are overused. IT diseases such as carpal tunnel and carpal tunnel syndrome have become familiar words. Among them, the eyes are the parts of the body that are hit by direct hits.

Last year, there was stimulating news that blue light caused blindness. Blue light refers to blue light in the visible 380-500nm (nanometer) region and is emitted from a display mounted in a computer, a notebook, a smartphone, and the like. It's less than the sun emits, but it's dangerous because it's used for a long time. Anxiety was amplified by a study at Toledo University.

However, the American Academy of Ophthalmology and others refute the findings. The study claims that the mouse retina is difficult to make a direct comparison, and the human eye already has the ability to protect the eye from blue light. In addition, there are differences in the study conditions and the way they are actually exposed to blue light.

It is unclear at this time that blue light causes direct eye disease. Rather, there are benefits. Receiving blue light during the day promotes `` serotonin '' secretion. Serotonin is a neurotransmitter that carries emotions and is called the happy hormone.

The framing is clear, but it shouldn't be indiscriminately exposed to blue light. After dark, exposure to blue light inhibits the secretion of melatonin, a bio hormone that induces natural sleep, which interferes with sleep and biorhythms. The later the blue light is, the farther away it is.

Smart blue light management is needed. If you're forced to face digital devices late at night, it's a good idea to wear blue-blocking glasses. Put a safety device between your eyes and the display. Smartphones, computers, tablets No matter what device you come in, you can count on glasses.

It also blocks blue light at the device level. Display brand BenQ also showed off its monitors with Low Bluelight, which blocks blue light, and Flicker Free, which eliminates the flicker of the monitor. Monitor flickering can cause symptoms such as fatigue and headaches.

Various operating systems (OS) such as iOS and Windows 10 are providing functions to reduce blue light such as their own night shift or night mode. Enabling night mode from sunset to sunrise can effectively manage blue light. The recent fad of dark mode is an extension. Dark mode reduces the strain on your eyes, especially in the dark. Dark mode also saves smartphone battery with OLED display. Stylish screen is a bonus. Applications are also adding dark mode options.

In fact, eye health requires attention to 'brightness' rather than blue light. A recent study found that dimming the screen made the eyes more comfortable than removing the blue light. As you may already know, it's better to stay away from light as you approach bedtime. Some studies show that people who use digital devices take longer to fall asleep than people who read paper books.

No matter how technology protects your eyes, there is a desperate need for action to protect your eyes on a personal level. This article will also be visible on the screen. Even now, look far away through the window and close your eyes for a while if you can't.
