Colored contact lenses are a very popular product on the market, because wearing them can make our eyes more beautiful. At the same time, we all know that colored contact lenses need to be replaced with care solutions. So do we need to change the care solutions for colored contact lenses every day? Do we need to keep colored contact lenses in the care solutions?

It is recommended that patients change the contact lens care solution every day when they wear contact lenses frequently, because contact lenses will be exposed to various bacteria, microorganisms and dust every day, so they should be soaked in the care solution after cleaning every day. The main ingredients of contact lens care solution are sodium chloride, wetting agent, preservative, taurine, etc., which can remove dust, impurities, bacteria and viruses accumulated on contact lenses. And when changing, do not pour the care solution directly into the box of the lens, but clean the lens and replace it with new care solution, otherwise the care solution may deteriorate, and bacteria may breed and contaminate the lens. After the contact lens is soaked in it for a period of time, it can become softer, making it more suitable for the eye environment, which can reduce the discomfort when wearing contact lenses.

When not wearing contact lenses, they must be soaked in the care solution. Contact lenses should be replaced regularly. It is not recommended to use the lenses for a long time. They must be strictly cleaned, rinsed, disinfected, soaked in the care solution, and placed in the storage room of the refrigerator. The solution should be changed once a week. When wearing them again, they must be cleaned, rinsed and disinfected carefully. It is very important to clean contact lenses. When using weekly disposable or long-wear lenses, in addition to rubbing them with disinfectant 5 to 10 times, it is also recommended to change the soaking box frequently to avoid dirt and grime in the box after using them for too long. It is best to use up or discard the soaked solution within 4 months to avoid the solution from deteriorating. The length of time you wear contact lenses every day actually depends on the condition of your cornea, but it is basically not recommended to wear them for more than 12 hours a day, and 5 to 6 days a week is recommended. If you wear contact lenses, you should be more cautious and not wear them for more than 10 hours a day. It is best to use them every other day. Do not wear them when you sleep.

The degree of beauty contact lenses should be 25 to 50 degrees less than the actual degree. Medical research shows that this way of wearing is more conducive to stabilizing and protecting vision, and can also reduce eye pressure. For example, if the naked eye vision is 100 to 300 degrees, the degree of beauty contact lenses remains unchanged or decreases by 25 degrees, 300 to 500 degrees decreases by 25 or 50 degrees, 500 to 700 decreases by 50 or 75 degrees, and 700 to 800 decreases by 75 or 100 degrees. Wearing a lens with a degree greater than your own myopia may aggravate vision. It is recommended to go to a regular hospital or pharmacy to re-configure glasses. Pay attention to daily care to avoid symptoms of eye fatigue. If the eyes have astigmatism, then the astigmatism is generally above 100 degrees, and the degree of astigmatism needs to be added. Generally, the degree of astigmatism is generally included in the contact lenses, but if it does not exceed 100 degrees, then there is no need to consider it.

There are two types of soaking time for contact lenses: one is for newly bought contact lenses, and the other is for previously worn contact lenses. Newly bought contact lenses generally need to be soaked for more than 6 hours and then rinsed before they can be worn. Previously worn contact lenses generally need to be soaked for at least 3 to 4 hours, because bacteria can easily hide between the fiber gaps of contact lenses. The most effective way to eliminate these bacteria is to disinfect them. Soaking the contact lenses in the care solution for 3 to 4 hours will be effective. It is best to soak them for 6 hours to better protect them. It is best to change the care solution once a day.
