Abstract: ordinary myopia should generally replace glasses once every two years, one is to adjust the degree, the other is to “update”. Once there are scratches on the glasses mirror, it will obviously affect its optical correction performance. Therefore, the glasses should be maintained and inspected regularly and updated in time to keep them in good working condition.
now the glasses have almost become an inseparable carry on item for the majority of myopia. Once the glasses are matched, they will not be replaced unless damaged. However, many people ignore the “service period” of glasses. However, if glasses “exceed the service period”, it is likely to accelerate myopia. Therefore, even if the glasses are still intact, they need to be replaced after a certain period of use.
among all kinds of lenses, resin lenses have been accepted by more and more people and become the main body of the glasses consumer market. However, relevant optometry experts point out that China is regarded as a windy and sandy area, and it is appropriate to replace the resin lens in 2-3 years. However, most current glasses wearers do not pay much attention to the cleaning and maintenance of the lens, which often causes scratches and cracks on the lens and shortens the overall service life of the resin lens. However, for the “extended service” lenses, the transmittance is reduced, It is easy to accelerate myopia due to visual fatigue.
then, how often is it most appropriate to change glasses?
ordinary myopia should be replaced every 2-3 years.
ordinary myopia should generally replace glasses every two years, one is to adjust the degree, the other is to “update”. Once there are scratches on the glasses mirror, it will obviously affect its optical correction performance. Therefore, the glasses should be maintained and inspected regularly and updated in time to keep them in good working condition. In fact, the best film change time is to change it every 2-3 years. Because most of the current glasses wearers do not know the maintenance of glasses, they do not realize the importance of glasses lens maintenance. In addition to correct optometry and glasses, good eyesight should also be guaranteed by high-quality lenses.
teenagers are best to replace them every six months to a year. The
teenagers are at the peak of eye use. Due to long-term close eye use, there will be ciliary muscle regulation spasm, and myopia is particularly easy to deepen. Teenagers with particularly rapid degree change are best to replace their glasses once a year (corneal shaping glasses for preventing and controlling the deepening of myopia in teenagers and children are generally replaced once a year to once a year and a half). Teenagers who use their eyes excessively should have optometry once every six months (mydriatic Optometry). If the glasses are no longer suitable for the change of myopia diopter, they should change them in time.
eyes are the windows of the soul. While protecting your eyes, don’t ignore your inseparable friend
