In this article we'll cover everything you need to know about potentially harmful blue light and blue light glasses.

As our world becomes increasingly digital, we find ourselves spending more and more time staring at screens. From laptops and smartphones to televisions and tablets, screens have become an inescapable part of our daily lives. But all this screen time comes at a cost - digital eye strain and disrupted sleep patterns. Digital eye strain, also known as computer vision syndrome, is a set of symptoms that can include:

• headaches,

• blurred vision,

• dry eyes and more.

It's caused by prolonged use of digital devices and the glare and blue light emitted by screens. Disrupted sleep patterns, on the other hand, are caused by exposure to blue light before bedtime, which can suppress the production of melatonin, a hormone that helps regulate our sleep-wake cycle.

The solution?

Glasses for screen protection - blue light glasses or blue light blocking glasses. These glasses can help reduce the amount of blue light that reaches your eyes, making it easier for you to work, play, and sleep.

The Science behind blue light lenses and visible light

Blue light is a type of light that is part of the visible light spectrum. It has a shorter wavelength and higher energy than other types of light, such as red or yellow. The blue light spectrum ranges from 380 to 500 nanometers. It's different from other types of light because it's more likely to cause eye strain, headaches, and disrupt sleep patterns.

There are both natural and artificial sources of blue light. Natural sources include the sun, while artificial sources include:

• digital screen

• TVs

• smartphones

• computer screen

• tablets

• fluorescent - bright lights

• and LED lights.

The natural blue light sources are beneficial for the human body, it helps to regulate our circadian rhythm but when it comes to artificial sources, it can be potentially harmful if exposed to it for prolonged periods of time, especially at night.

It's important to be mindful of the amount of time spent in front of the computer screen and the brightness and color temperature of the lights in your home and office, to reduce the negative impact of artificial blue light on your health.
