Why are some people not nearsighted even though they are playing with their phones? !

appendix:

1. Myopia may affect some career choices

Myopia not only causes inconvenience in life, but also affects further study and employment. For example, soldiers, pilots, firefighters, etc. have strict requirements on vision. In recent years, many people have been eliminated from the military due to substandard vision. Some cutting-edge scientific research, precision instrument research, aviation, navigation and other professions have even stricter requirements on vision.

2. Any claim that myopia can be cured is not credible.

Once myopia occurs, it is irreversible because once the eye axis is stretched, it cannot be restored. All current methods, such as glasses and laser surgery, can only correct vision rather than cure it. Any claim that myopia can be cured is not credible.

3. If adults do not pay attention to eye protection, myopia will still increase

Although the eyeballs of adults have matured and their vision is more stable than that of teenagers, it does not mean that they will not become myopic or that their myopia will not increase in adulthood.

Nowadays, many young and middle-aged people are "head-down people". They have to face the computer for 6-8 hours a day, and they can't help playing with mobile phones and tablets after get off work. Long-term close-range use of eyes, coupled with incorrect eye habits, can easily cause visual fatigue. If the eyes are in a state of fatigue for a long time and cannot be improved or adjusted, it may cause ciliary muscle spasm, which will then cause myopia to deepen.
