Why Blue Light is Bad for You and What You Can Do About It


Have you been spending more time in front of the computer than usual? Whether it’s because of the work-from-home culture brought about by the pandemic or because you’ve had more time to binge-watch your favorite shows and movies, spending too much time staring at a computer isn’t good for you. Not only has blue light been linked to eye issues, but it can also affect other areas of your life.

What is Blue Light?

The visible color spectrum is composed of different colors, one of which is blue. This blue light has more energy and shorter wavelengths than other colors in the spectrum and is emitted by various gadgets, including computers, smartphones, tablets, and TVs. Although not as bad as ultraviolet (UV) rays, blue light raises concerns for people’s health, particularly their eyes.

How Does Blue Light Affect the Eyes?

With so many people using electronic devices nowadays, computer vision syndrome (CVS) has become more prevalent. Some symptoms associated with CVS include eye strain, blurred vision, irritated eyes, and dry eyes. Exposure to blue light via different gadgets could also lead to eye inflammation, cataracts, and visual damage.

If you sometimes get headaches after working for prolonged hours in front of a screen, this might be due to blue light exposure.

How Does Blue Light Affect Sleep?

Your eyes aren’t the only thing that blue light might harm. It might harm the quality and length of your sleep, as well. While any type of light can prevent melatonin secretion, blue light is said to affect it even more. Harvard researchers have shown that blue light can actually suppress melatonin two times longer, as well as change the body’s circadian rhythms (the body’s 24-hour internal clock) two times more. This makes it harder for people to fall asleep.

If you use your phone in bed with hopes of getting sleepy as you scroll or watch something. the blue light might actually signal your brain to stay awake instead. It would therefore be advisable to avoid using any gadgets before bed altogether.

How Does Blue Light Affect Your Skin?

In the same way that UV rays could damage your skin, studies show that blue light exposure increases intracellular oxidative stress, which could speed up the aging process. That aside, too much exposure to blue light could also result in swelling, pigmentation, and redness.
