What are the benefits of blue light glasses?

What is blue light?

There are many types of light that we are exposed to every day. One of them is blue light. Blue light is a type of light that has a very short wavelength, which gives it more energy.

Blue light is not only a part of sunlight, but it is also present in many artificial light sources, such as LED lights and fluorescent lights. In addition, digital screens used in our daily lives, such as TV screens, computers, smartphones and tablets, are among the most significant sources of blue light. The constant exposure to these screens can have significant consequences for our health.

LED light	Lighting in the home, workplace
Digital screens	Computers, smartphones, tablets, TV screens

One of the biggest concerns about long-term exposure to blue light is its potential to cause eye damage. Because blue light has a shorter wavelength and higher energy than other colors in the visible spectrum, it can penetrate deeper into the eye tissue. This can disrupt circadian rhythms, affecting sleep, causing eye fatigue, and possibly leading to long-term problems such as an increased risk of age-related macular degeneration (an eye disease that can eventually lead to vision loss).

What are blue light glasses?

Blue light glasses are specially designed glasses that filter or block blue light before it reaches the eyes. This is done by using a special surface treatment that either absorbs the blue light or reflects it away from the user's eyes. Blue light glasses can therefore reduce the negative impact of blue light on the eyes and reduce the risk of eye damage and sleep disorders.

Why use blue light glasses?

Studies have shown that blue light filters can have positive effects on circadian rhythm, productivity and work performance. By reducing eye strain, for example, blue light filter glasses can reduce fatigue and discomfort, which can affect one's focus and concentration.

Benefit #1: Reduction of eye fatigue

One of the most immediate benefits of blue light glasses is that they can help limit digital eye strain, which can cause symptoms such as dryness, redness, itching, and blurred vision.

Benefit #2: Improving sleep quality

Blue light has been shown to disrupt the body's natural sleep cycle. By blocking blue light, these glasses can help regulate your sleep cycle and improve your sleep.

Benefit #3: Prevention of eye injuries

Prolonged and continuous exposure to blue light can potentially lead to damage to the retina of the eye, which can cause serious health problems such as age-related macular degeneration or cataracts. By filtering out some of this blue light, blue light glasses can protect your eyes and reduce the risk of developing these diseases.

Benefit #4: Increased productivity

If you work in front of a screen for many hours, you may experience eye strain, headaches and fatigue, which can affect your productivity and well-being. By blocking blue light, blue light filters can counteract such discomfort. With a blue light filter, you can therefore work longer without experiencing discomfort, while also reducing the risk of long-term damage to your eyes. Thus, glasses with a blue light filter can help improve both work performance and job satisfaction.
