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

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.
