Abstract: 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 who use their eyes excessively should have optometry once every six months (mydriatic Optometry). If the glasses are not suitable for the change of diopter of myopia, they should change them in time.
ordinary myopia patients should generally change their 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.
after wearing glasses, many people often wear them all the time until they are broken or can’t be used. According to a recent large-scale survey, among consumers who use resin lenses, 29.2% only change a pair of glasses every three years or more, and 36.4% only change glasses when they are worn out. In fact, if the lens is “extended service”, it is likely to accelerate myopia, but most glasses wearers know little about it. Teenagers who change the degree of
very quickly should change their glasses once a year or half a year. 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 who use their eyes excessively should have optometry once every six months (mydriatic Optometry). If the glasses are not suitable for the change of diopter of myopia, they should change them in time. Of course, if it is pseudomyopia, after mydriasis, the eye can recover after rest and drug treatment, without glasses.
it should be emphasized here that when teenagers change glasses, they must have mydriasis and optometry. Optometry glasses should not be careless, and must be matched according to the optometry prescription issued by the regular hospital. In addition to subjective optometry, mydriatic optometry should be used. If the ocular muscle regulation function of teenagers is too strong, mydriatic optometry can understand their real refractive state and diopter. The diopter of the matched lens and the diopter on the optometry sheet shall be consistent. If the deviation exceeds the national standard, the development of myopia or hyperopia will be accelerated.
presbyopic glasses for the elderly should also be replaced regularly. Presbyopia is caused by lens aging. With the increase of people’s age, the degree of lens aging will increase. Only by increasing the degree of lens correction, can it meet the needs of the daily life of the elderly. There is no uniform provision on the specific replacement time. When the elderly feel hard to read the newspaper with glasses and their eyes are sour and swollen, they should be replaced.
there are many lens materials on the market. Resin lens is light and easy to carry, but it is easy to scratch. Pay special attention to lens maintenance. Glass lenses are cheap, but fragile. Once broken, they may cause extremely serious damage to the eyes, so they are not suitable for teenagers who exercise more.
