Glasses have changed for two years. After wearing glasses, they tend to wear their glasses out until they are broken or unusable. According to a recent large survey, 29.2% of consumers who use resin lenses change glasses every 3 years or more, and 36.4% change glasses when glasses are broken. In fact, if the lens is "expired" it is likely to cause eye myopia to accelerate, and most eyeglass wearers know little about it. Ordinary myopia patients should change their glasses every two years, one is to adjust the degree, the other is to "update dressing."
Once the glasses are scratched, it will obviously affect their optical correction. Performance, so regularly maintain and check the glasses, and keep up to date, so that they are always in good working condition. Young people with a very fast academic change are advised to change their glasses once every six months.
Due to long-term close-ups, adolescents use eye peaks with the eye, there will be ciliary muscle regulation, and myopia is particularly easy to deepen. Adolescents who use excessive eyes should undergo a half-year optometry (hospital optometry). If the glasses are not suitable for myopic diopter changes, please change the glasses in time. Of course, if it is pseudo myopia, after the sputum expansion, the eyes can go through rest and medication, vision can be restored, no glasses are needed.
It is important to emphasize that young people must change their glasses to perform optometry. The optical glass is sloppy and must be based on prescriptions prescribed by regular hospitals. In addition to subjective optometry, optometry should use dilated optometry, and the eye muscle regulation function of adolescents is too strong. Astigmatism can be used to understand their true refractive status and diopter. The diopter of the lens should be consistent with the diopter on the optometry plate. If the deviation exceeds national standards, it will accelerate the development of myopia or hyperopia.
