Monthly contact lenses can only be worn for one month, that is, 30 days. Contact lenses can be divided into daily polishing, monthly polishing and annual polishing. The service life of monthly polishing contact lenses is one month. Even if they are not worn often, they can't be worn again after being disassembled for one month, so as to avoid damage to the eyes.
Many people will be short-sighted for one reason or another. At this time, they need to wear glasses to correct their eyesight. However, for young people, framed eyes are not good-looking, and wearing them is easy to cause pain in their nose and ears. At this time, they often choose to wear contact lenses.
According to the service cycle, contact lenses can be divided into daily throwing, monthly throwing, annual throwing and so on. Monthly throwing is understood literally, that is, it is discarded after wearing it for a month. Generally speaking, contact lenses will come into contact with the air after unpacking. Even if they are soaked in the nursing solution, bacteria will breed, so it is recommended to use them within the specified time.
Some wearers will think that not wearing contact lenses often will prolong its life. In fact, this is wrong. The service life of monthly throwing contact lenses is one month, which is equivalent to the shelf life of food. Using them beyond the limit will cause damage to the eyes.
