How to choose and save contact lens care solution?
When wearing contact lenses, the eyes are dry and itchy every time, we are always the first to think about the lens itself, but in fact, the problems caused by improper lens care are not rare.Most people are very cautious when buying contact lenses, but they may be more casual in the choice of care solution, and there is no concern about the preservation and use of the care solution.
The main component of the contact lens care solution is sodium chloride and preservatives. It is a special kind of syrup for cleaning, disinfecting and preserving the lens. It can effectively kill bacteria and fungi on the surface of the lens, protect the eyes and prevent infection.Although all the care solutions are marked with the functions of washing and sterilizing, the effects are not exactly the same. Even some powerful bactericidal and antiseptic substances can stimulate the conjunctiva and corneal cells, and long-term use may cause eye discomfort.
The care solution is actually a medical device like a contact lens. When purchasing, you must look for the health license number on the package.At the same time, to see the function of the care solution, do not use the single-function care solution as a multi-purpose care solution.The ultimate goal of the care solution is to ensure that the lens is hygienic. If the care solution in your hand is only clean and moisturizing, you must purchase another bottle of care solution with sterilization function.
Before use, please read the instructions carefully and follow the instructions. Usually, the care solution should be placed in a cool place at room temperature to avoid deterioration caused by direct sunlight.Bathrooms, refrigerators, etc. are humid, easy to breed bacteria, not suitable for placing contact lenses and care solutions.Generally, the unopened care solution can be stored for one year, and the expiration date is three months after unpacking. After the expiration, the cleaning function of the care solution is significantly reduced and should not be used any more.
