How long can colored contact lenses be used?

How long can cosmetic contact lenses generally be used? The shelf life of cosmetic contact lenses cannot be determined solely by whether the lens surface is intact, but rather depends on the validity period and usage cycle of the cosmetic contact lenses. The validity period of cosmetic contact lenses is generally three to five years. They can be worn as long as they are within the validity period. There are many usage cycles for cosmetic contact lenses, including daily, biweekly, monthly, semi-annual, and annual.

Each usage cycle of cosmetic contact lenses represents a period of time: daily disposable is one day, bi-weekly disposable is two weeks, monthly disposable is one month, and so on.

It should be noted that cosmetic contact lenses can be divided into short-cycle and long-cycle. Generally speaking, short-cycle lenses can be worn directly according to the cycle time, but long-cycle lenses cannot. Among all cycles, quarterly, semi-annual and annual disposals are long cycles, and the others are short cycles.

Long-cycle lenses are worn for a long time, so not only are there a lot of bacteria deposited on the surface, but the lenses will also be worn after long-term cleaning, affecting the wearing comfort. Therefore, if you wear semi-annual disposable contact lenses, they generally need to be replaced after about 5 months of wearing, and annual disposable contact lenses need to be replaced after 8 to 10 months.

While wearing cosmetic contact lenses, if there are any scratches or damages on the surface of the lenses, you cannot continue to wear them and need to replace them immediately.

As cosmetic contact lenses are items that come into direct contact with the cornea, if they have been worn by someone else, it is best not to use the same pair of cosmetic contact lenses interchangeably with others. Because everyone's eye condition is different, health level is different, and refractive power is also different. If you wear lenses that have been used by others, it can easily cause eye discomfort or eye infection.

How long you can wear cosmetic contact lenses depends mainly on how long you use them. The editor here reminds all fairies to avoid buying contact lenses that have a short usage time, because the longer you wear them, the more protein and other sediments will accumulate on them, which cannot be completely washed off and will increase the incidence of eye diseases. So don't choose contact lenses that you use for too long.
