Old people or young people, children are all the same, they are emotional, and they all like to play these games or chat tools. But old people often play with mobile phones, which can also be harmful. The harm of old people watching mobile phones every day mainly includes inducing or aggravating vision loss, causing cervical spondylosis and inducing other eye diseases. It is suggested that family members spend more time with the elderly, communicate with the elderly and reduce the time for the elderly to use their mobile phones. 1. Induce or aggravate vision loss: the elderly watch mobile phones every day. If the time is too long and it is too close to the screen of the mobile phone, the ciliary muscles will be too tense, resulting in decreased vision. The eyes of the elderly have already experienced visual deterioration, so they are more prone to visual deterioration. In severe cases, myopia surgery may be needed to cure it. 2, causing cervical spondylosis: In addition to myopia, if you look at the mobile phone posture improperly, or keep the same posture for a long time, it will cause local oppression, resulting in limited blood circulation and increased neck buckling pressure, which may also cause cervical spondylosis; 3. Induce other eye diseases: With the increasing age of the elderly, the body's resistance is not as good as in the past. If the eyes stay on the mobile phone for too long, the blue light on the electronic screen will stimulate the retina, leading to eye fatigue, decreased immunity and weakened resistance to pathogens in the air. In addition, if you don't pay attention to eye hygiene, it is easy to cause bacterial infection, induce eye diseases such as conjunctivitis, dry eye and keratitis, and appear uncomfortable symptoms such as blurred vision, sore eyes and foreign body sensation in the eyes. In addition, if the elderly spend too much time watching mobile phones every day and reduce outdoor activities, it will also increase the incidence of diseases such as venous thrombosis, diabetes, tenosynovitis and scapulohumeral periarthritis. Therefore, the elderly can be encouraged to go downstairs more and communicate with their peers more. If physical conditions permit, you can also play Tai Ji Chuan to kill time.
