There is an opinion that it is better to watch TV with the lights on. How true is this? And what about mobile phones?
Yes, it is indeed true.
As ophthalmologist Anna POLOVIKOVA explained, visual fatigue when watching TV in complete darkness occurs more quickly. This is because the constantly changing brightness of the image causes different types of cells in the retina to continuously react to light, leading to the constriction and dilation of the pupil.
Prolonged dilation of the pupil, especially in people over the age of forty, can hinder the drainage of intraocular fluid, which, in turn, can lead to increased intraocular pressure. This condition can result in glaucoma. Therefore, it is recommended to watch TV with soft point lighting.
The same advice applies to mobile phones.
