What happens if the contact lens care solution has expired? _Contact lenses_
Whether it is contact lens or contact lens care solution, in fact, there is a certain shelf life. Generally, the different shelf life will be written directly on the packaging box, so be sure to pay special attention to the shelf life. All of the products in China have a clear shelf life. If it is a temporary product, we will directly inform you, so it will be relatively easy to buy suitable contact lenses and care solutions. But what if I accidentally use an expired contact lens care solution? 1. How long will the contact lens care solution expire? Normally, the contact lens care solution will expire three months after opening, so we must pay special attention to the situation of opening. In particular, some large bottles of contact lens care solution may not be usable at ordinary times, so we must pay special attention to the time of opening, so as to ensure that there will be no problems with the subsequent wearing of good contact lenses. Therefore, it is recommended to replace it after three months of opening. Second, pay attention to the shelf life of new products. Because many contact lenses themselves are about to expire, we still have to look at the shelf life on the packaging, so that it can be guaranteed to be used. So everyone must pay special attention to the basic care solution for contact lenses, and whether the shelf life has expired. Generally speaking, the shelf life of contact lens care solution is about two to three years, so you should be a little cautious when using it. 3. What impact will the expired contact lens care solution have? Because the contact lens care solution has expired, the sterilization performance must be greatly reduced. If it expires for a long time, it may not even be able to dissolve the basic protein. The care solution has no protective effect at all, and there are also many problems. It is recommended that if you have found that the contact lens care solution has expired, then do not continue to use it, otherwise it may cause bacteria to grow, so that our eyes will also be greatly affected.
