Laser tv is the best type of TV with eye protection effect at present, which has scientific basis. We all know that traditional TV is either lit by pixels or diodes. In short, the light source is at one end of the screen, and the picture light will directly enter the eyes, with higher brightness and greater stimulation to the eyes. Laser tv uses diffuse reflection imaging. After the light source is emitted, we can see the picture on the screen by reflection imaging, which means that the light emitted by the light source does not directly enter the eyes, which is less irritating.

There is no evidence in the text, and laser tv's eye protection effect is authoritative. 2065438+2008 China Institute of Electronic Technology Standardization Cisse Laboratory and Peking Union Medical College Hospital ophthalmologists issued certificates to prove laser tv's eye protection characteristics.

The expert group selected 36 people, divided into 6 groups, and conducted a two-day test under the same conditions. The subjective and objective evaluations of human eyes before and after watching the same size laser tv and LCD TV at a certain time (90 minutes) and a certain distance (3 meters) were compared, and 144 groups of test data about human vision, diopter, tear film rupture, ciliary muscle flexibility and human subjective feelings were obtained.

The test results show that after watching traditional TV, human eyes will have obvious changes in vision, diopter and ciliary muscles, as well as symptoms such as eye swelling, eye pain, photophobia, dry eyes and blurred vision. However, after watching laser tv, the changes of key indicators such as vision and subjective feeling of eyes are not obvious.
