Glasses are different from lens production. It is the optometrist who performs subjective or objective optometry on the wearer. After comprehensive analysis and judgment, the optometrist will record the measured data in the prescription and submit it to the production unit to make glasses with special requirements according to the prescription.

Spectacle wearer's vision is decreased due to physiological or pathological reasons, and glasses can correct vision. Because the factors such as the physiological characteristics of the optician, the degree of vision loss, and the method of vision correction are not the same, the optician prescription varies from person to person, and the data listed in the prescription are not the same. Therefore, the production of glasses can only be processed in a single piece. The items listed in the optometry prescription are the technical parameters that must be based on for the production of glasses and are also necessary for product acceptance.

If you use your eyes too much, it is easy to cause the degree of myopia to deepen. Therefore, it is suggested that you must combine work and rest, and do not use your eyes too much. You need to pay attention to looking at the distance and rest your eyes for ten minutes when learning to read for half an hour, which can reduce the deepening speed of vision as much as possible, avoid the occurrence of high myopia, and control the degree of myopia growth in cooperation with the corneal plastic lens.
