Blue light is harmful to the health of users, so many technology manufacturers now integrate Low Blue Light technology into their products. So what is Low Blue Light and why is it so popular, let’s find out.

What is blue light, is it harmful?

Sunlight is usually considered white light, consisting of various colors such as red, orange, yellow, green, blue, indigo, violet, and many others. These colors correspond to different wavelengths and energies of light.

Blue light has a wavelength range of 380 nm to 500 nm, which is a wavelength range close to UV radiation, a type of radiation that can cause cancer. Blue light not only exists in natural sunlight but also appears in artificial light sources from devices such as phones, tablets, laptops, and other electronic screens.

Blue light, especially from electronic devices such as mobile phones, tablets, and laptops, can cause some negative effects on health, such as:

Eye strain: Prolonged exposure to blue light can increase feelings of tiredness and tension in the eyes. This can lead to redness, eye pain, and discomfort.
Sleep: Blue light can affect the body’s natural cycle, especially the production of melatonin – a hormone that helps regulate sleep. Exposure to blue light in the evening can reduce sleep quality and cause difficulty falling asleep.

Mood and emotions: Some studies suggest that blue light can affect mood and emotional state, increasing stress and anxiety.
Vision: High-intensity blue light can cause eye-related problems such as reduced vision, discomfort, and blurred focus.
Cardiovascular health: Prolonged exposure to blue light in the evening can also affect the body’s biological heartbeat system.

What is Low Blue Light technology and what are its advantages?

Low Blue Light technology is designed to minimize blue light in the range of 420 to 480 nanometers. Meanwhile, Low Blue Light Plus technology not only eliminates blue light but also filters out harmful radiation in the range of 420 to 455 nanometers. This helps maximize the impact of blue light on the eyes while maintaining good image quality and not affecting color display.

To meet the needs of users and protect their eyes, Low Blue Light technology provides different modes:

Multimedia mode: Optimized for watching videos, playing games, and multimedia entertainment.
Web Surfing mode: For those who frequently use the screen for web browsing.
Office mode: This mode is suitable for office work and prolonged screen use.
Reading mode: Optimized for reading books and online newspapers on the screen.
These modes help adjust the level of blue light according to different usage situations, providing a comfortable experience and health protection for users.

Benefits of Low Blue Light technology

As mentioned above, direct exposure to blue light can damage the eyes and cause various health problems. When using screens to watch videos, work, or play games for long periods, strong blue light can penetrate the eyes and affect the macula, leading to macular degeneration, computer vision syndrome (CVS), and other eye health issues. Additionally, blue light can also reduce the production of the hormone melatonin, causing sleep disturbances.

However, not all effects of blue light are negative. It also has some benefits such as enhancing alertness, improving memory, enhancing cognitive function, and regulating the natural sleep-wake cycle of the body.

Low Blue Light technology does not completely eliminate blue light on the screen but helps reduce the amount of blue light emitted. Screens that use this technology have the ability to adjust the level of blue light based on user activity. For example, reduce it by 20% when surfing the web, 30% when watching movies, 50% when working with text, and 70% when using the computer in low light conditions. This helps protect the eyes and reduce the negative effects of blue light during screen use.

Some products on the market that use Low Blue Light technology

Asus Laptop

ASUS’ blue light reduction technology is designed to minimize the amount of blue light emitted by up to 70%, and has received multiple certifications from TUV Rheinland – a professional organization for product testing according to international standards.

In addition, the anti-glare and anti-flicker technology, along with the premium ergonomic design, have been cleverly integrated into ASUS products. This helps users have the best experience and maximum eye protection when using the company’s products.

Viewsonic Monitor

With a similar operating principle to the Night Light feature on Windows, this application allows users to adjust the level of blue light filtering with 100 levels, gradually reducing from 100 to 0 (the lower the level – the lower the level of blue light). At the minimum level, the app can reduce up to 87% of blue light on the screen.

Frequently asked questions

Blue light is a color in the visible light spectrum and is emitted by the sun and digital device screens such as computers, tablets, and smartphones. While it has some benefits, excessive exposure to blue light can be harmful, causing digital eye strain and sleep disorders.

Low Blue Light Technology filters out and reduces the amount of blue light emitted by digital device screens. This technology adjusts the color temperature of the light, reducing the proportion of blue light and making the screen appear warmer, with a yellow or orange tint.

The main benefit of Low Blue Light Technology is that it reduces the negative impact of blue light on our health. By reducing blue light exposure, it can help alleviate digital eye strain, including symptoms such as dry eyes, blurred vision, and headaches. Additionally, by reducing blue light intake in the evenings, it can improve sleep quality and help maintain a regular sleep schedule.

Yes, many devices now offer ‘night mode’ or ‘blue light filter’ settings that can be manually activated. These settings adjust the color temperature of the screen, reducing blue light emissions. Additionally, some devices allow you to schedule these settings to turn on and off at specific times of the day.

While Low Blue Light Technology has many benefits, some people may find that the warmer color temperature of the screen affects their viewing experience, particularly when it comes to color accuracy. However, most devices allow you to adjust the intensity of the filter, so you can find a balance that suits your preferences and comfort level.
