Now, with the rapid development of electronic products, a variety of electronic products gradually stimulate our eyes. Now there is a kind of laser TV. Can laser TV protect our eyes? Listen to the experts.
Thirty six ophthalmologists were divided into six groups and tested under the same conditions for two days. The subjective and objective evaluation values of the eyes before and after a certain time (90 minutes) and a certain distance (3 meters) watching the same size of laser TV and LCD TV were compared. 144 groups of eye vision, diopter, tear film rupture, ciliary muscle flexibility were obtained And the test data of human subjective feelings.
Data analysis and comparison confirmed that: after the subjects watch LCD TV, they will have obvious changes in vision, diopter and ciliary muscle, as well as symptoms such as eye swelling, eye pain, photophobia, dry eyes, blurred vision; after the subjects watch laser TV, the changes of key indicators such as vision, subjective feelings of the eyes are not obvious. The study also found that the long-term over contraction of the ciliary muscle is easy to cause myopia. After watching LCD TV, the ciliary muscle fatigue is obvious. After watching laser TV, the ciliary muscle tends to be more flexible. It can be seen that under the same conditions, watching laser TV is not only more comfortable, but also can protect the eyes to a certain extent.
Dr. Liu Xianrong, an expert in laser TV, pointed out that the characteristics of laser TV health eye care are determined by its luminous imaging principle. Liquid crystal or OLED TV adopts direct imaging, and the light of large screen directly enters the eyes. Moreover, with the problems of highlighting and stroboscopic refresh, the larger the size is, the longer the viewing time is, the more likely it is to cause visual fatigue. The laser TV reflects the light to the viewer's eyes through the screen, just like all things in nature reflect the sunlight and finally enter the eye, the light is soft, comfortable and not dazzling.
In the first half of 2018, the sales volume of laser TV in China increased by 326.32% year on year, according to the data of China Yikang. As the 'inventor' of laser TV, Hisense laser TV's sales volume and sales volume in August accounted for 94.46% and 94.82% of the whole laser TV market, accounting for half of China's color TV market of more than 80 inches.
