Currently, using electronic devices to work for long periods of time leads to deterioration of eye health due to increased exposure to blue light. Many screen technologies are researched to bring comfort and eye health to users. Low Blue Light technology was born to accomplish that goal, let’s find out with thtrangdai.edu.vn what this technology is!
What is blue light?
In sunlight, often considered white light, there are red, orange, yellow, green, blue, indigo, violet and many other color ranges depending on the energy and wavelength of the light rays.
Blue light has a wavelength from 380 nm to 500 nm, a wavelength very close to the wavelength of UV radiation – the type of radiation that can cause cancer. This is a form of monochromatic light that appears in natural and artificial sunlight sources. Blue light is also present in light sources coming from phones, tablets, laptops and other electronic display devices.
What is Low Blue Light technology?
Low Blue Light Technology eliminates blue light (420 ~ 480nm) while Low Blue Light Plus Technology filters harmful radiation (420 ~ 455nm) to minimize the harmful effects of blue light while maintaining quality Best image, does not affect display colors.
To best protect users’ eyes, Low Blue Light has different modes to suit the user’s screen usage needs:
- Multimedia Entertainment Mode (Multimedia)
- Web Surfing Mode
- Work Mode (Office)
- Reading mode
Benefits of Low Blue Light technology
Harmful effects of blue light
Visible light enters the retina and causes damage to the eye. When we use screens to watch videos, work or play games for many hours, strong blue light enters our eyes, affecting the macula of the retina.
This can lead to macular degeneration, Computer Vision Syndrome (CVS), and other eye-related diseases. Blue light can inhibit the production of the hormone melatonin, leading to insomnia.
However, blue light also has benefits for humans such as: increasing alertness, increasing memory, enhancing cognitive function and improving human physiological and psychological conditions. Helps regulate circadian rhythm (the body’s natural wake and sleep cycle). Exposure to blue light during the day helps us maintain a healthy circadian rhythm.
Therefore, Low Blue Light technology does not completely eliminate blue light on the screen but reduces blue light. Depending on the user’s activities, the screens offer appropriate levels of blue light, for example: 20% reduction when surfing the web, 30% when watching movies or 50% when working with documents, or 70% % when using the computer in low light conditions.
