What does it mean to have contact lenses around the month and year to be abodied?

Weekly, monthly, and yearly are the discarding dates of contact lenses, and they are calculated according to the discarding date after opening.

Weekly contact lenses are thrown once a week and require daily care.

Month-disposable contact lenses are thrown once a month and require daily care.

Annual disposable contact lenses are thrown once a year, and they need daily care, and it is recommended to replace them after 9-10 months of wearing.

Weekly Disposable Type: It can only be used for one week, and it cannot be used again.

Monthly type: This contact lens can be used for one month and needs to be replaced.

Annual disposable type: This contact lens can be used for one year and needs to be replaced.

The daily throw is a one-time one, wear a day and lose it, and so on, the month throws that is a month to lose, and the year throws that is a year and then throws away.

Weekly throwing type for one week, monthly throwing type for one month, and annual throwing type for one year.

You can take it for a week, a month, or a year.

If you only wear it once or twice occasionally, it is recommended to choose a daily disposable for the eyes; If you wear it for a long time, it is recommended to choose monthly and annual disposal, but you must pay attention to cleaning to avoid breeding bacteria, so as to achieve the purpose of being good for your eyes.

Let's talk about the difference between yearly, monthly and daily contact lenses from 4 perspectives:

1. The difference in time:

Daily disposal: The use time is 1 day, the daily disposal is one-time, and the used day is thrown away on the same day.

Monthly Disposal: The use time is one month, and the monthly disposable can be reused.

Annual Disposal: The use time is one year, and the annual disposable can be reused.

2. Differences in hygiene:

Daily disposal: Throw it away after using it on the same day, so it is the most hygienic.

Monthly disposal: The use cycle is only one month, and the protein precipitation is less and relatively clean.

Annual disposal: The use cycle is one year, due to the need for repeated use, there will be protein precipitation after a long period of use, which needs to be cleaned with a care solution, and the longer the use time, the more serious the wear will be, and the more likely it is to produce some small bacteria.

3. The difference in water content:

Daily disposal: the water content is generally more than 50%, because it is only used for one day, and it does not need to be used repeatedly, so the water content is high.

Monthly Disposal: Moisture content - generally 38% to 42%, need to be used repeatedly Low water content.

Annual disposal: The water content is generally 38% to 42%, because it needs to be used repeatedly, in order to improve the comfort, so the water content is generally not too high.

4. Cost-effective difference:

Daily throwing: the lowest cost performance, because it is too expensive, the use time is short, and the eyes are easy to dry after wearing it for a long time, so babies who often want to use contact lenses should not consider daily throwing.

Monthly throwing: the most cost-effective, ** and the daily throw is not too much, but the use time is longer than the daily throw, much cleaner and more hygienic than the annual throw.

Annual Disposal: **Slightly higher, super long use, so relatively cheapest. However, bacteria that are invisible to the naked eye are produced.

So, the comprehensive information can be seen:

To a large extent, the hygiene problems caused by improper care are avoided by daily disposable contact lenses. However, the water content of daily disposable is generally around 45%, which makes the eyes feel very moist and comfortable when you first wear your glasses. It also means that it "dries" quickly in the eyes and absorbs moisture from the eyes, making the eyes uncomfortable and dehydrated.

Monthly and annual contact lenses are relatively cost-effective, and one or two hundred contacts can be worn for nearly half a year or a year. Not only that, the water content of contact lenses is from 38% to 45%, and people can choose to put different water content according to the specific situation of their eyes, and their eyes will not feel dry all day.

In summary, from the perspective of cost performance and eye tolerance, monthly or annual delivery is better than daily delivery; From the perspective of hygiene, the daily throw is better than the monthly or annual throw, so each has its own advantages.
