Therefore, Professor Singh of Yale University suggested that children should not watch TV until they form good study habits. As a science and technology worker, the blue radiation of LCD TV is naturally harmful to children's eyes. Although I began to understand my children's circle of friends from loneliness, and realized the importance of animation in children's growth and the "positive energy" of some high-quality animation, this did not become the reason why I let LCD TV and mobile phone hurt Jessica Hester Hsuan's eyes. This is really a good choice for parent-child families.
The projector can reflect light. Both TV and mobile phone illuminate the screen, so the screen is bright and irritating to the eyes. When using the projector, the movie we see is reflected light, and the picture is softer and closer to natural light than TV and other equipment, so it is not easy to get tired when using the movie projector. Of course, the larger projection size will also make children involuntarily stay away from the screen when watching movies, and at the same time will not stare at a certain point on the screen, which is obviously more conducive to protecting children's vision. Mainly because of boredom! With nothing to do and no one to play games with him, he thought of TV.
