What does daily, monthly, and annual contact lenses mean?

1. What does daily disposable mean?

It refers to contact lenses with a shelf life of one day. You can use them directly after opening the package and throw them away on the same day after use. Daily disposable contact lenses are the most hygienic because they will not recur. Because of this, the price is relatively the most expensive. If you only need to wear colored contact lenses occasionally, you can choose daily disposable ones, but if you wear them for a long time, the cost of daily disposable ones will be particularly high.

2. What does monthly disposable mean?

It refers to contact lenses with a shelf life of 30 days. Generally, the longer the shelf life, the cheaper the price will be, but at the same time, they require more careful care. Monthly disposable contact lenses are different from daily and biweekly disposable contact lenses in that they are more expensive, and also different from annual and semi-annual disposable contact lenses that require careful care. They are basically thrown away after about a month of use, and the price is also moderate. Babies who like to change the style of contact lenses can try monthly disposable contact lenses.

3. What does annual disposal mean?

It refers to contact lenses with a shelf life of 1 year, which is the limit of the shelf life of contact lenses. In order to ensure that the contact lenses can be used for one year, the requirements for materials and production are relatively high. Therefore, due to the strict national requirements, Japanese contact lenses are at most monthly disposable, and there are no contact lenses with a longer period of use.

The difference between daily, monthly and annual contact lenses

1. From the perspective of usage time

Daily disposable: It can be used for 1 day. It is disposable and should be thrown away on the same day after use.

Monthly disposable: The usage period is one month and the monthly disposable can be reused.

Annual disposable: The usage period is one year and the annual disposable can be reused.

2. From the perspective of life

Daily disposable: thrown away after use on the same day, so it is the most hygienic.

Monthly disposable: The usage cycle is only one month, with less protein precipitation and cleaner.

Annual disposable: The usage cycle is one year. Due to repeated use, protein will precipitate after a long period of use and it needs to be cleaned with a care solution. The longer it is used, the more serious the wear will be and the easier it will be to produce some small bacteria.

3. From the perspective of water content

The water content does not actually refer to the moisturizing degree of the contact lenses, but the amount of water required to keep the contact lenses moist. Therefore, the higher the water content of a pair of cosmetic contact lenses, the eyes are more likely to feel dry in order to keep the lenses moist.

Daily disposable: The water content is generally above 50%. Because it is only worn for one day and does not need to be used repeatedly, the water content is high.

Monthly disposable: The water content is generally 38% to 42%, and needs to be used repeatedly with low water content.

Annual disposables: The water content is generally 38% to 42%. Because they need to be used repeatedly, in order to improve comfort, the water content is generally not too high.

4. From the perspective of cost performance

Daily disposable lenses: The lowest cost-effectiveness because they are too expensive, have a short usage time, and can cause dry eyes after wearing for a long time. Therefore, those who often use cosmetic contact lenses should not consider daily disposable lenses.

Monthly disposable: The most cost-effective, the price is not much different from daily disposable, but the usage time is longer than daily disposable, but not as long as annual disposable. It is much cleaner and more hygienic than annual disposable.

Annual disposable: average cost-effectiveness, slightly higher price, and very long usage time, so it is relatively the cheapest. Because lenses will wear out after being worn for a long time and produce bacteria that are invisible to the naked eye, and most people don’t pay attention to the cleaning of lenses, it is better to replace them regularly.
