1.Q: Myopia is around us all the time, so how should we protect our eyes and prevent myopia? What is a scientific eye hygiene habit? A: The main factor that causes myopia in students is too much and too close eye use, so it is more important to prevent myopia and reduce the burden on the eyes. The government, society, hospitals, schools, parents, and students all have the responsibility to make efforts. For the government, society, schools and parents, the first priority should be to reduce the workload of students’ close eye use, reduce the burden of students, control the time of students’ study, and enroll in fewer interest classes, which will have a positive effect on the prevention of myopia if implemented effectively. However, nowadays, schools and parents are often worried about students not learning enough, which requires us to reflect on this point. The most important thing for students is to develop scientific eye health habits, first of all, reading and writing posture should be correct, which is what we usually say before “three one”. Second, we should pay attention to the eye distance can not be too close, when using the eyes, away from books, cell phones, iPAD, etc. at least a foot away, at least half a meter away from the computer. Third, we should reduce the time of continuous eye use, reading, writing, using computers, cell phones, etc. for half an hour to an hour, should take a break, especially during recess, must go outside the classroom to take a break, eye rest is mainly far away, look at the distant scenery, and see as clearly as possible, five to ten minutes. In addition, be careful not to lie in bed to read, not in a moving car or airplane in such a shaky environment, and do not read and write in too strong or dark light. 2.Q: Prevention of myopia, pay attention to reading and writing posture “three one” why is important? A: The incorrect pencil grip developed from childhood is indeed a major cause of myopia. Because of holding the pen too close to the pen tip, fingers blocked the pen tip and write out the word, children will inevitably have to bury their heads, head from one side to see, thus causing too close to the writing distance, increasing the burden on the eyes, of course, over time may lead to myopia. So as parents and teachers should urge students, when reading and writing to pay attention to the “three one”. The “three one” means, hold the pen fingers from the pen tip distance of one inch, that is, two horizontal finger distance; read and write from the book distance of one foot, that is, more than 33cm; chest from the edge of the table a fist, keep the upper half of the body upright. For the correct posture of holding a pen, in addition to the fingertips from the tip of the pen an inch, the thumb and index finger should hold the body of the pen, the other three fingers into a half fist, the body of the pen and the desktop into 45-60 degrees. Some students prefer to wrap their thumbs around the body of the pen, which may also result in the thumb obscuring the nib, and should back the thumb out and hold it opposite the index finger. It is important to note that teachers and parents focus more on the students’ grades and sometimes just talk about the “three ones” without serious correction. Only when children develop good habits from childhood will the occurrence and development of myopia be reduced as much as possible. 3, Q: should I wear glasses if I am myopic? Many parents think that their children are still young, do not want them to wear glasses too early, one is not good-looking, worried about the belt will wear a lifetime. Secondly, they are worried that their eyesight will increase after wearing them, which will affect their eyesight when they grow up, so as long as they do not affect their studies or their lives, they are not recommended to wear glasses. A: If you are nearsighted, you should wear glasses after the correct medical examination. It is certainly not right to avoid glasses when you are nearsighted. If myopia is present, parents should acknowledge the reality that just because they don’t wear glasses, the child is not nearsighted. In addition to eye hygiene, which we have emphasized time and time again, proper prescription of glasses is a key measure to slow down the development of myopia. In the adolescent stage, myopia is, in general, a developmental trend, and reasonable glasses are an important measure to slow down this trend, which will increase even faster without glasses. Therefore, myopia, should be under the guidance of doctors medical optometry, reasonable prescription, and half-yearly review, if necessary, change the lens. 4, Q: Is there a cure for myopia? Do the advertised instruments or vision training work? A: There is no exact and effective method to cure myopia. There is no scientific basis to show that the instruments or so-called vision training methods can cure or reverse myopia. These advertisements often exaggerate their role and mislead parents, thus not only bringing financial losses, but also delaying the correction of myopia in young people. We believe that the relevant departments should step up their efforts to outlaw such advertisements and behaviors. 5.Q: Can Chinese medicine treat myopia? A: Traditional Chinese medicine methods, including acupuncture, cannot treat and reverse existing myopia, they only have a role in controlling the occurrence and development of myopia, and the premise must be based on the premise of scientific eye use and reasonable prescription. It is extremely wrong to blindly believe that TCM can cure myopia and refuse to get glasses. Now there are many unscrupulous hospitals and doctors in society who are using the guise of “TCM can cure myopia” to deceive and abuse TCM, so we need to shine our eyes. 6.Q: Chinese medicine can prevent myopia? A: Chinese medicine does have its own advantages in preventing and controlling the increase in myopia. In addition to the eye exercises mentioned earlier, acupuncture, auricular pressure pills, massage, herbal plasters and other Chinese medicine methods do have a certain role in clinical practice, and we are also vigorously promoting and using them in clinical practice. However, we should emphasize two points: First, the most important thing to prevent myopia and control the increase of myopia is to reduce the burden of study, pay attention to eye hygiene, myopia should be medical optometry, correct prescription, under this premise, and then use Chinese medicine methods is the most scientific attitude and method. Secondly, TCM is not a panacea. For myopia, especially the so-called true myopia, which is the organic elongation of the eye axis, TCM cannot treat or reduce the degree! The focus of TCM is only to prevent or control the increase of myopia! There are many unscrupulous clinics and doctors in the society who are trying to cheat under the banner of TCM treatment for myopia, which needs to be banned for the attention of the whole society and parents to avoid being cheated and delaying the prevention and treatment of myopia! 7.Q: Dry eye is becoming more and more common, which symptoms are the performance of dry eye?

Patients should try to reduce the time of watching TV and using computer and cell phone, consciously blink more while watching TV and using computer and cell phone, and appropriately adjust the position of TV and computer screen so that it is below the line of sight.

The key point of prevention and treatment is that diabetic patients should actively and smoothly control blood sugar, in addition to fasting blood sugar, postprandial blood sugar should also be controlled to the ideal range; in addition to diabetes, other diseases such as hypertension and hyperlipidemia should also be actively dealt with. Diabetic patients should have regular follow-ups at the ophthalmology clinic for six months to a year. If fundus manifestations of diabetic retinopathy appear, fundus angiography should be performed under the guidance of a doctor, and fundus laser photocoagulation and other symptomatic treatments are needed if necessary to avoid rapid vision loss and to preserve long-term useful vision. Chinese medicine has obvious advantages in the prevention and treatment of diabetic retinopathy, and proprietary Chinese medicines have been marketed specifically for diabetic retinopathy.
