Blue light, which includes sunlight, is a wavelength of light. It is a type of visible light on the light spectrum and has a short wavelength of 415 to 455 nanometers. Because of this, blue light rays contain more energy than other light types.

Short wavelengths of blue light penetrate the back of the eye, causing damage to the retina. Long-term exposure also damages the muscles and causes macular degeneration (a condition in which a person loses their central vision and cannot see fine details).

Though the sun is the ultimate source of blue light wavelengths, you can see a rapid increase in the usage of artificial sources of blue light too.

Today, almost every workplace or household uses LEDs, and even the electronic devices you use for work or personal use have built-in LEDs.

According to data from DataReportal published in March 2022, the average American spends 7 hours and 4 minutes in front of a screen every day.

Especially after the Covid period, almost every aspect of life went online. Working from home culture has increased the exposure to blue light wavelengths over the years. Screens have become a part of your lives like never before.

It has now become your source of news, entertainment, social interaction, and communication. And with work from home being more common than ever, it can be very taxing on your eyes.

If you look for sources of blue light, you will find them everywhere. You can find it naturally in the sunlight. But most commonly, the electronic devices that we use, like computer screens, laptops, mobile phones, and even smart TVs, are made up of liquid crystal displays (LCDs), which look super clear. Yet, they release the highest amount of blue light wavelengths.

Despite our best efforts, we cannot avoid digital screens. Instead, we must learn how to protect ourselves from the negative side effects of screen use.

How Does Blue Light Affect Your Health?

A blaring office environment or staring at a screen most of the time can make you feel tired from staring.

Again, excessive exposure to blue light can have a negative impact on both your physical and mental health. It can even lead to many health problems among teens and adults as well.

"But blue light from screens can negatively affect your sleep cycle and contribute to digital eye strain, according to UC Davis Health."

To a great extent, blue light disturbs the body's natural circadian rhythm. It can cause macular degeneration and several eye diseases like dry eyes. It is due to the excessive use of short wavelengths.

These wavelengths have a great deal of energy reaching your eyes compared to the much wider wavelengths at the other end of the spectrum.

The bright overhead light at work or the light emitted from digital devices can even disrupt your sleep cycle. It can cause a suppression of melatonin and lead to insomnia or trouble getting sound sleep.

Again, lower melatonin levels might explain the association between sleepless nights and daytime fatigue. Sleepless nights can lead to short-term insomnia. It impairs cognitive function, thus affecting memory, attention span, and the ability to reason.

Further, persistent insomnia can also lead to many physical and mental health problems. It can cause issues like cancer, diabetes, heart disease, depression, anxiety, and obesity.
