First of all, the harmful blue light we mentioned here refers to the high-energy short-wave blue light with the wavelength between 420 and 455 nm. The harm of this short-wave blue light to human eyes is mainly manifested in the pathological injury of the eyes and the rhythmic injury of the human body that leads to myopia, cataract and macular degeneration.
The LED screen backlight of electronic products needs the effect of white light, and the industry uses blue LED mixed with yellow phosphor to form white light. Because the blue LED is a main hardware, the blue spectrum in this white light has a peak, which forms what we call the problem that harmful blue light hurts the eyes.
Therefore, in order to reduce the harm of blue light, consumers will take various protective measures. One is "anti-blue light", such as anti-blue glasses, but it still can't completely filter out the harmful blue light band. There is also a "low blue light", that is, from the screen, through software control, to reduce the emission of harmful blue light bands, but also to achieve no blue light at all. The TV that everyone uses for entertainment every day is also facing the problem of blue light. Although manufacturers are also promoting blue light prevention and low blue light, due to the principle of screen lighting, blue light cannot be eradicated.
Laser tv, which is rapidly spreading, has natural advantages in health and eye protection. Laser tv is a "new species" in TV field. The combined route of "laser light source+ultra-short focus lens+light shield" is adopted. Light is projected from the host to the screen, and then indirectly enters the human eye through the reflection of the screen. Because it is an indirect light source, laser tv's imaging principle is consistent with the principle that human eyes accept natural light to perceive everything, which is more eye-protecting.
Hisense laser tv, the most popular company, has made further progress in eye protection with the top laser display technology in the industry. In terms of laser, it actively avoids harmful blue light in all bands of 455nm, becoming the only laser tv brand in laser tv to achieve zero harmful blue light.
Therefore, Hisense laser tv has been recognized by various social organizations and experts by virtue of its category advantages in laser tv and its ability of zero harmful blue light. From June 5th to February last year, ophthalmologists from Peking Union Medical College Hospital and Cisse Laboratory conducted a TV contrast experiment. The results show that people who watch LCD TV for a long time will have certain symptoms such as eye swelling, eye pain, photophobia, dry eyes and blurred vision. Seeing Hisense laser tv has no obvious visual changes and eye discomfort, and the visual comfort is better, which is more conducive to protecting eye health. Previously, when the Shanghai Municipal Education Commission suggested that the online classroom should be dominated by TV and supplemented by the Internet, Li Dejiao, an ophthalmologist from China-Japan Friendship Hospital, directly suggested that parents choose laser tv, because reflective imaging can effectively filter harmful light and protect children's vision health.
On March 16, at the "315+e" 2022 health science popularization party jointly organized by the Health Communication Committee of Chinese Medical Doctor Association, China Family Newspaper, Health and Healthy Culture Promotion Platform of National Health and Wellness Committee and Shell, Wang Kai, a professor at Optometry Center of Peking University People's Hospital, also suggested that laser tv should be recommended for prevention and control of myopia among adolescents.
Compared with the traditional LCD TV, laser tv products represented by Hisense laser tv have more obvious advantages in viewing comfort and eye protection, which can effectively reduce visual fatigue and help prevent myopia among teenagers. If your family is going to change TV, upgrade the traditional LCD TV to Hisense laser tv for the sake of the eyesight health of family members, especially children!
