Surely many people are familiar with the statement that prolonged TV viewing reduces visual acuity and the shorter the distance to it, the stronger the negative consequences.
However, while watching TV, the gaze is motionless and directed only to one plane. This is bad for the muscles of the optic organ, which eventually lose their elasticity. As a result, the functionality of the lens decreases and vision decreases.
The picture on the screen, especially on older devices, flickers and blinks constantly. Such a rapid change in brightness leads to overstrain of the eye muscles and organ fatigue.
Watching TV shows for our body turns into hard physical work. At the same time, in the dark, a negative effect
During the construction of the whole image, the brain uses the inertial property of consciousness. The central organ of the nervous system puts together a continuous picture from many fragmentary frames-fragments.
Changing frames on the TV is fast and non-linear. This overloads the nervous system and affects vision. Excessively bright colors and high wavelength light are perceived as irritants and lead to overexcitation.
However, it was not possible to prove the negative influence of the TV. American scientists from Ohio University
The negative effects of watching TV are no better than those of reading a book or watching a movie on a smartphone. The eyes also get tired and tired. The only way to avoid vision loss is with minimal eye strain.
