To begin with, it’s worth figuring out whether watching films on a blue screen is harmful to our eyesight.
The answer is unequivocal - prolonged viewing of TV is harmful to your health. Ophthalmologists give many arguments, having studied which it is necessary to limit the time you spend in front of the screen.- The eyes focus on one point and this is undesirable. This is a long static load, which may well lead to deformation of the lens, it may lose the ability to quickly change.
- Constant flickering on the screen leads to the fact that the pupil narrows or expands, it is also harmful.
- Retinal degradation as a result of poor-quality images.
This is only part of the negative factors that affect your health when watching TV for a long period of time.
Why not watch TV in the dark?
When watching TV in a dark room, a very high contrast is maintained between the light source and the surrounding darkness. Therefore, our eyes are trying to adjust, which leads to rapid fatigue, our eyes get tired.
When watching TV, it is worth considering that the brightness of the backlit image changes regularly, and this is also an increased eye strain. In a dark room, the pupil should be large, and with a bright - small. With a constant change in the brightness level, the pupil will resize, which will lead to rapid fatigue of your eyes.
The problem is not only due to the fact that the room is dark. It is also the fact that the eye should focus for a long period on a specific object. He is constantly in tension.
IMPORTANT. A dynamic change in the load on the visual organ can lead not only to excessive fatigue, but also to the development of a very serious disease - glaucoma. Symptoms of the development of this disease are increased pressure in the organ and the development of vision problems.
So, having examined the behavior of the eye organ when watching TV in the dark, we can conclude that this is not worth it. It is best to arrange movie shows in a room where the light is turned on, it is desirable that the light source does not fade in the technology screen.
