Doctors have found that these people have a common habit of using their mobile phones frequently and for a long time before going to sleep. When lying down, using the phone, the human eye gets used to the light of the mobile phone and sees the darkness at the same time, the natural system of the brain, which cannot perceive day and night at the same time, is lost and confused. Therefore, it has been found that it has a very bad effect on vision. The fact that the blue light emitted by mobile phones is harmful beyond our imagination has been linked to the increase in people's eyesight and serious eye diseases in the last 20 years. Ophthalmologists say that due to the use of mobile phone lights in the dark, early vision loss has increased, their vision has reached the same level as a 75-year-old person's vision, and that not only affects vision, but the organism should be considered as the main cause of disease. It was received with a level of alarm and warned to get rid of this habit and not to fall into such a habit.
