Eye care 1. Regular eye examination.
Humans can open their eyes to see the world soon after birth until the end of their lives. The development of human eyes has also gone through several stages, including infants, children, teenagers and even middle-aged and elderly people. Maybe you've heard of children with amblyopia and strabismus, or you used to be a middle school student.
If you are worried about the increasing degree of myopia, you may feel the inconvenience caused by high myopia and hyperopia, or worry that you can't read the fine print in the newspaper clearly. In short, no matter how good your eyes are, the problem of optometry will always accompany us all our lives.
If we always pay attention to eye health, leave the corresponding physical examination data in different periods and establish a systematic personal eye optometry file, it is very important for doctors to fully understand the condition and formulate the best correction and treatment plan.
Deputy director Zheng Yingde pointed out that in the past, people didn't pay attention to the change of refractive state of eyes, and always thought of going to the hospital for examination after the problems appeared. In fact, a person's body and eyes are like a complicated machine. If you don't pay attention to regular maintenance, maintenance and overhaul, there will be failures. In addition, we should also develop the good habit of doing regular physical examination to prevent delay and ensure the safety of you and your family.
Eye care II. Medical optometry
Most people are probably used to the street, right? Free optometry? Signs always think that optometry means inserting some lenses in front of your eyes until you can see the fine print on the eye chart clearly, and then you can choose the frame.
Zheng Yingde believes that this ancient traditional technology has been used by human beings for two centuries, and in most cases it is inaccurate and incomplete. Therefore, the measured results are often far from the actual degree or actual needs of patients, and glasses will cause a lot of discomfort, thus causing visual damage. In addition, many optometrists do not have some basic medical knowledge, and it is easy to miss the diagnosis of some serious eye diseases, such as glaucoma and keratoconus, which delays the treatment opportunity and causes irreparable huge losses to patients. Therefore, whether the glasses fitting procedure is scientific, whether the fitting personnel have comprehensive professional quality and whether the instruments and equipment are complete and accurate will directly affect the correctness of the results.
Today, with the rapid development of science, a complete optical matching process includes not only accurate optometry, the selection of frames and lenses, but also a series of ophthalmological examinations, because the refractive state of the eyes will be affected by many diseases of the eyes and the whole body. Optometry is a medical behavior. Professional doctors should conduct a comprehensive and systematic examination of your eyes and related conditions, get the correct prescription, and give detailed guidance on the use of corrective tools, so as to ensure the safety of your eyes.
Third, eye protection, sitting posture leads to myopia.
Many parents get used to their children's bad eye habits when their eyesight is still good, such as sitting incorrectly, watching too much TV and lacking enough attention. As we all know, myopia may be? Quietly arrival, when you find your vision blurred, you have done everything you need to do. It is better to pay attention and prevent it as early as possible than to be very eager to give children glasses at that time. Xu Guangdi, a famous ophthalmologist, also believes that there is no radical cure for myopia so far, and prevention is the main method to deal with myopia. ?
Because children are lively and active by nature, self-control is not formed and there is no awareness of preventing myopia. Most children have incorrect posture when reading and writing, and like to bow their heads, bend over and even write on their desks. This not only oppresses the internal organs, hinders blood circulation, affects the growth and development of bones, but also makes the eyes worse. The distance between eyes and books is too close, which easily leads to myopia. Adults should always urge their children to correct their wrong sitting posture.
Eyes can see the scenery clearly by adjusting the eye muscles, and the adjustment function of eyes is closely related to age. The older you get, the smaller the crystal adjustment is. Long-term close-up use of the eyes leads to overuse of the eye's accommodation function, and there is not enough residual accommodation power to spare, which makes the eyes easily tired and forms pseudomyopia. Over time, the anterior and posterior diameter of eyeball becomes longer, leading to true myopia, severe loss of vision, and some even develop into high myopia. Long-term close eye use is the main cause of students' myopia, which must be paid attention to by schools and parents.
Parents should educate their children to have a good sitting posture, pay attention to the head and neck, and stand upright. Three ones? One foot, one punch, one inch. That is, when reading and writing, the distance between the eyes and the book should be more than one foot; Keep your fist distance from the desk; When lifting the pen, keep your hand one inch away from the nib.
The vision health intervention project for primary and middle school students in the near amblyopia prevention base in Henan Province [1] has been started since July 2002, and more than 70,000 primary and middle school students have been provided with free optometry files and vision care cards. With this health card, students can go to the Health Center of Education Bureau for vision examination and consultation at any time. All the information will be written into the student optometry file and kept in the Student Health Center of Education Bureau. The optometry file will follow the students until they leave school and graduate. Let glasses care for glasses, which has been forced by the situation and the general trend, is worthy of attention and put into practice as soon as possible.
Eye care IV. Eye protection and care
Although the pursuit of health has become a new fashion in modern society, ophthalmologists have found that people ignore the protection and care of eyes, and many people have misunderstandings about eye health care. Most people go to the doctor when their eyes are sore or they can't see clearly. Some middle-aged and old friends often buy a pair of reading glasses at the stall because they can't read newspapers; After the children's eyesight drops, parents blindly buy eye health products, hoping to cure myopia once and for all, which reflects people's lack of knowledge about eye hygiene, especially optometry.
Ophthalmic health care v. Ophthalmic optical diseases
Speaking of. Ophthalmic optical diseases? People may find it strange, but I'm afraid no one is unfamiliar with myopia, hyperopia and presbyopia. These are all optometry diseases, and the people who wear glasses every day are also optometrists. People wear glasses to correct their eyesight and even have laser surgery. These optometry correction methods have long been commonplace.

According to statistics, there are more than 300 million myopia patients in China, and the demand for glasses reaches 70 million pairs every year. Zheng Yingde, deputy director of peking university health science center Ophthalmology Research Center, said that the number of optometry patients in China is amazing. According to statistics, the incidence of myopia among teenagers alone is as high as 50%, and other optometry diseases are also increasing rapidly. In the past two years, they have gone deep into state organs, primary and secondary schools, military units, communities and other places to provide free optometry services for cadres, students, soldiers, residents, etc., and have conducted systematic optometry surveys on 1 10,000 people of different ages and occupations. The statistical results show that:
1. People with different degrees of ametropia account for more than 70% of the total number of people examined. Among them, about 50% patients did not find their own ametropia, and about 30% patients had obvious errors in glasses, which seriously affected normal visual function.
2. The incidence rate of all kinds of institutions, scientific research institutions, primary and secondary schools is about 80%, which is much higher than that of the general population, which is mainly related to excessive close reading and heavy eye burden of these people.
3. Many other eye diseases were also screened out, including keratoconus, cataract, abnormal intraocular pressure, iridocyclitis, retinitis, diabetic retinopathy and hypertensive retinopathy.
