Harm of playing mobile phone for a long time before bed
1. In the dark environment, luminous electronic products such as mobile phone or tablet before bedtime will cause continuous irritation to the eyes and make the eyes more prone to fatigue due to the large brightness contrast between the screen and the surrounding environment.
2. Eye injury. When lying on the side of the bed playing with the mobile phone, it will cause great pressure on the left and right eyes, compress blood vessels, cause insufficient blood supply, and soon lead to vision deviation of the left and right eyes.

In this way, myopia and even astigmatism will occur within a month. Especially for children under the age of 3, it is necessary to see bright things for less than or equal to 15 minutes to avoid damage to their eyesight.
3. In addition to affecting the eyes, the mobile phone before going to bed will also affect the sympathetic nervous system and adrenal hormone secretion, disrupt the physiological cycle and reduce the sleep quality.
