When we were in the hospital, we often saw many doctors who were nearsighted and wore glasses. Almost every hospital was like this. They work hard every day to treat patients. As he grew older, he became nearsighted. However, why do they clearly know that they are nearsighted? Why don't they change this situation through surgery and get a good eyesight? In fact, the main reason for this problem is that everyone's needs are different. For example, although everyone may be in a sub-health state, few people really go to the hospital to treat their sub-health. Different needs mean different things. Some people improve their eyesight through surgery in order not to wear glasses, which is their demand.

As doctors, they can also wear glasses to complete their daily work. For them, myopia will not have much influence on them, let alone cause their career. So we must treat this problem dialectically. Although there are many methods in medicine that can help our bodies to get some changes, not everyone needs them.

First of all, doctors don't need much vision in their work. Doctors' job is to save lives, which is their main business. Good eyesight won't have much effect on them. Only by improving one's medical skills can one help oneself and improve one's professional ability. Even if they wear glasses, they are doctors who save lives and will not be affected at all.

Second, doctors know that surgery will affect their eyes, although surgery can help them get better eyesight. But from the future development, after the operation, with the development of time, it will bring some sequelae, which is not conducive to their health. As doctors, they know the result clearly, so they don't need surgery.
