Can we buy and use the myopic table in Shanghai Eye Hospital?
Myopia is a common ophthalmic problem, which affects the daily life of a large number of people. For myopic patients, glasses or contact lenses are a common way of correction, and the myopia table, as an auxiliary tool, has more advantages in accuracy. But is it true that some people think that myopia watches can only be used in hospitals? Now let's discuss it.
1. Function and function of myopia watch
Myometer is a widely used auxiliary inspection tool, which is mainly used to measure vision. It uses a series of letters, numbers and symbols to evaluate the vision of patients by measuring the smallest font size that patients can recognize at different distances. The myopia chart can help doctors accurately judge vision problems and formulate corresponding treatment plans.
At the same time, myopia table is also a common ophthalmic screening tool, which is used to detect possible vision problems. Myometer is widely used in schools, driving license tests and recruitment physical examinations. It can help screen out potential vision problems and ensure the quality of people's daily life and work.
2. Provisions for use scenarios of myopic meters
According to the Guidelines for the Diagnosis and Correction of Myopia issued by the Chinese Academy of Ophthalmology, the use scenarios of myopia tables mainly include specific occasions such as medical institutions, schools, vision tests, driver examinations and occupational physical examinations. In these scenarios, professional doctors or trained personnel will adopt standard inspection procedures to ensure the correct use of the myopia table and interpretation of the results.
Therefore, according to the regulations, the general population has no right to purchase and use myopia watches. As a professional medical tool, the myometer needs to be used by professional doctors or qualified personnel to ensure accurate measurement results.
3. Correct use of myopia watch
For users in medical institutions, the use method of myopia watch is trained and standardized. The user needs to keep a certain distance and select one by one according to the letters or symbols shown on the table. For different distances and conditions, doctors will adjust according to standard procedures to ensure the accuracy of test results.
For the general population, it is still very important to keep a good habit of using eyes, although they cannot buy and use a myopia watch. Proper use of electronic equipment, balanced diet, proper eye exercises and regular eye examinations are all effective ways to protect eyesight.
4. Limitation and development of myopia table
Although the myopia table, as a common auxiliary tool, has certain accuracy and judgment ability, it also has certain limitations. First of all, myopia table can only be judged based on vision, and cannot be judged for some other eye diseases or early symptoms. Secondly, for some low vision patients, the myopia table may not be able to make accurate judgments because of the serious decline in vision.
In order to solve these problems, in recent years, with the continuous development of ophthalmic technology, some new vision testing methods have emerged. For example, the application of automatic refractometer, wavefront sensor and other technologies has improved the accuracy and comprehensiveness of vision inspection. In the future, with the further development of technology, the diagnosis and correction of vision problems will become more accurate and convenient.
Summary
Myometer is a common ophthalmic auxiliary tool, which is mainly used to measure vision and screen ophthalmic problems. According to the regulations, the general population cannot buy and use a myopic watch, and its correct use needs to be operated by a professional doctor or qualified personnel. Although myopia table has some limitations, with the development of ophthalmic technology, the diagnosis and correction of vision problems will become more accurate and convenient.
