Myopia is associated with a number of factors. Playing with cell phones increases the likelihood of developing myopia, but is not a major contributor to myopia, but prolonged use of electronic devices is not recommended.
The cause of myopia is not completely clear, and may have more to do with genetic factors. In addition, environmental factors and poor eye habits can also increase the chances of developing myopia. If there is no myopia in your family, and you can rest and adjust your eyes after playing cell phones or using other electronic devices for a long time, your chances of developing myopia will be reduced.
Studies have shown that the incidence of myopia is higher among people who use their eyes at close range for a long period of time. Therefore, you should avoid studying and reading in poorly lit environments, and reduce the time you spend using cell phones and other electronic products.
