What is Low Blue Light Plus Technology?

2022/05/01

What is Blue Light?

Light can be divided into visible light and invisible light. The part that can be perceived by the human eye is called visible light, and comprises wavelength from 400 nm to 700 nm. The colors we usually see, for example, red, orange, yellow, green, turquoise, blue, and violet, all belong to the visible light spectrum. Light having a wavelength longer than 700 nm is called infrared light, and wavelength shorter than 400 nm is called ultraviolet light (UV).

Recent studies have shown that UV light may damage biological tissues, including skin and eyes. People now understand that using sun block products can prevent skin damage. While it is highly unlikely for humans to stare directly at sun light (UV) or infrared light under normal circumstances, chances for infrared light and ultraviolet light damage to eyes are generally quite slim. However, visible blue light is allowed to enter the retina. We can separate visible blue light into two groups - short wavelength blue light (420 nm to 455 nm) and long wavelength blue light (455 nm to 480 nm).

Effects of Blue Light

Recent studies have shown that UV light may damage the biological tissues of your eyes, and causes a series of damages.

Blue light which can penetrate crystal might damage tje tissues of eyes.

Cornea

The cornea is the first part of the eye that comes into contact with light. For example, irradiating corneal cells with high-intensity, high-energy blue light may trigger a series of oxidative reactions, making the cornea easily inflamed, resulting in dry eyes.

Crystal

Crystals protect the retina by filtering out some high-energy light, including blue light. However, because of the absorption of this high-energy light, the crystal will gradually become cloudy and get cataracts.

Retina

At present, cell experiments and animal experiments have shown that too much blue light will increase the chance of retinal cells getting injured, and may even cause Age-related Macular Degeneration (AMD).

Based on the above reasons, we usually need to do appropriate protection against blue light. First of all, most of the blue light in life comes from the sun, so people need to wear hats, parasols, or sunglasses when they stay outside, which is the easiest and most effective way to prevent cataracts. When we are indoors, our pupils get larger. Many people like to use their mobile phones in the dark, and the retina receives a lot of blue light stimulation for a long time, which may cause Age-related Macular Degeneration. Therefore, do not ignore the blue light because indoors. Wearing anti-blue light glasses, or using products with low blue light mode can reduce the risk and make the eyes more comfortable.

BenQ Low Blue Light Plus

In 2012, BenQ adjusted monitors' RGB color temperature parameters and rolled out four types of color temperature presets based on user scenarios. Additionally, BenQ cooperated with TÜV Rheinland to define low blue light testing standards and develop a certification. BenQ thus created the world's first low blue light certified display.

BenQ Low Blue Light Plus technology utilizes a specially designed blue chip to avoid short wavelength blue light (420 nm ~ 455 nm) emission while retaining the long wavelength blue light (455 nm ~ 480 nm), allowing users to experience the ultimate color reproduction with undistorted colors, high sharpness, and contrast. In the meanwhile, preventing potential vision problems and providing ultimate image quality.
