How do blue light glasses work?

Introduction to blue light glasses

In today's digital society, where computer screens, smartphones and tablets often dominate our everyday lives, our eyes are constantly exposed to blue light. And this is where blue light glasses come in as a solution. Blue light glasses, also known as blue light blocking glasses, are designed to filter or block the blue light that digital screens emit. These glasses are indispensable for many people, especially those who spend many hours a day in front of screens. Blue light glasses can help reduce the harmful effects of blue light on our eyes and reduce the risk of digital fatigue.

What is blue light?

Blue light is a type of light with a wavelength between 380 and 500 nanometers. It is part of the visible light spectrum and can be seen naturally in the white light of the sun. However, like anything else, too much blue light can have negative effects, especially when it comes from artificial sources such as digital screens or energy-efficient fluorescent and LED lights. These artificial sources can emit even more blue light than the sun, which can have a detrimental effect on our health.

How does blue light affect our eyes and body?

Exposure to blue light, especially in the evening, can affect our sleep and overall health. Blue light suppresses the body's production of melatonin, a hormone that helps us fall asleep. It can also cause digital fatigue, which is a set of symptoms that can include eye strain, headaches, blurred vision, dry eyes, and trouble sleeping.

What are blue light glasses and how do they work?

Blue light filter is a special coating that helps absorb and block blue light from digital screens. This coating is typically a yellow or amber coating on the lens that allows it to filter blue light. When blue light passes through this filter, its intensity is reduced, thereby reducing the damage and discomfort caused by prolonged screen use.

Blue light glasses can reduce the symptoms of digital fatigue, but they are not a universal cure for all eye problems. It is also important to note that not all blue light glasses are created equal. The quality and effectiveness can vary greatly depending on the manufacturer, design, and specific blue light technology used.

Who can benefit from blue light glasses?

Blue light glasses are especially useful for people who spend a lot of time in front of a screen, including students, office workers, designers, programmers, and gamers. People who are sensitive to light or those who often experience tired or burning eyes after prolonged screen use may also benefit from blue light glasses.
