Turning on and off the lights will directly affect the background brightness when watching TV.
When watching TV, if you turn off all the lights, the background will be very dark, and the small and bright fluorescent screen forms a strong contrast with the background. Over time, our eyes will feel tired, just like we stare at the lights for a long time; watching TV in an all-black environment will also increase the consumption of A-type vitamins in the body.
If you turn on all the lights in the house when watching TV, the fluorescent screen will appear dark under the bright background, which will reduce the contrast and grayscale of the image, and the image will become light and unclear, which will greatly affect the viewing effect. If you see such unclear pictures for a long time, it will also affect our vision.
In this way, when watching TV, it is not good to turn off all the lights, and it is not good to turn on them all. It is best to turn on a small light bulb with a low wattage and softer light indoors, which is better to have a cover to adjust the brightness of the background in the room, so that the eyes do not feel tired, and the reception effect is good. At the same time, it can also reduce the consumption of vitamins in the body.
The following two issues should be paid attention to when placing small wattage lights: First, this light should not appear in people's field of view when watching TV, so as not to distract and produce unnecessary stimulation; second, the light should not be directed to the fluorescent screen to avoid affecting the image quality.
