In fact, the damage to the eyes of the computer screen mainly comes from the blue light emitted by the screen.

What is Blue light?

Blue light is light with a relatively high energy wavelength between 400nm and 480nm. It is part of the visible spectrum and can penetrate the lens directly to our retina. If this happens, it will cause irreversible visual damage and even cause eye diseases.

The effects of blue light on health

 

  1. Digital eye fatigue

    Blue light is easier to scatter than other visible light and is not easy to focus on. This visual “noise” when looking at digital devices reduces the contrast and causes digital eye fatigue. You may experience eye fatigue, headache, blurred vision, dry glasses, neck and shoulder pain.

  2. Age-related macular degeneration

    Blue light can damage the light-sensitive cells in the retina, and may also cause age-related macular degeneration, which can lead to permanent vision loss.

  3. Circadian rhythm disorder

    Among all kinds of artificial light, blue light has the greatest impact on human sleep. Blue light inhibits the production of melatonin in the body.

    Melatonin is a hormone produced by the pineal gland, which helps your body know when to sleep and wake up.

    Usually, at night, your body produces more melatonin. Once the sun starts to go down, the level of melatonin secretion starts to rise. This indicates that the body is ready to fall asleep. When the sun rises, the level of melatonin secretion starts to decrease. , The body gradually began to wake up. Excessive exposure to blue light at night and insufficient melatonin secretion in the human body will keep people awake and unable to fall asleep, which causes the problem of insomnia.

    Researchers at Harvard University and colleagues conducted an experiment comparing the effects of 6.5 hours of blue light exposure with green light exposure of comparable brightness. Blue light inhibits melatonin for about twice as long as a green light, and the circadian rhythm changes twice (3 hours vs. 1.5 hours).

    In another study on blue light, researchers at the University of Toronto compared the melatonin levels of people exposed to bright indoor light and wearing anti-blue light goggles with those who were exposed to regular dark light without wearing goggles. Human melatonin levels.

    The fact that the hormone levels in the two groups are roughly the same strengthens the hypothesis that blue light is an effective inhibitor of melatonin
