secret 1 the service life of lenses is generally no more than 3 years.
some people wear glasses for more than ten years and think “what does it matter if the lenses are not broken anyway?” But in fact, the lens has a service life. At present, the common resin lens is changed every 2 ~ 3 years. When we find that there are white spots on the lens that can’t be wiped off, in fact, the film of the resin lens has fallen off, which suggests that we should change our glasses.
secret 2 glasses can’t be picked up with one hand
in most people’s cognition, it’s always so handsome to pick up glasses with one hand! But in fact, glasses can not be taken off with one hand. Taking off glasses with one hand will cause uneven stress on both sides of glasses, which is easy to cause frame deformation.
secret 3 after the adaptation period, the new glasses are still dizzy, indicating that the glasses are not equipped with
“the new glasses are dizzy and dare not walk”. I believe this is what many nearsighted friends have personally felt. But is this really a normal reaction? In fact, not necessarily, this may also be caused by poor matching of glasses! In fact, after the adaptation period, well matched glasses generally will not have such a reaction again. After the adaptation period, wearing glasses is still dizzy, which may be due to inaccurate astigmatism axis; It is particularly bright and the vision is reduced. It may be too deep; Nausea and vomiting may be due to inaccurate pupil distance.

secret 4 to clean the lenses, wash the
and
glasses with clean water first. After wearing them for a period of time, the lenses will become dirty. At this time, the glasses need to be cleaned. When cleaning, we should wash the lens with clean water first, otherwise the small polluting particles on the lens will rub the lens during scrubbing. After washing, wash it again with neutral soap or shampoo. After washing, wipe the lens directly with clean spectacle cloth or soft paper towel. Of course, the spectacle cloth will wear out after a long time, so it also needs to be replaced in time.
secret 5 children with myopia have to go to the hospital ophthalmology or professional fitting institution
in case of vision problems, do not match glasses blindly. First go to the hospital ophthalmology or professional fitting institution for mydriatic optometry. The adjustment ability of human eyes is very strong. It is easy to have visual tension after reading at a close distance, resulting in the illusion of myopia. After mydriasis, the ciliary muscle is relaxed, and the degree after recovery is the closest to the real number.
