Wash your hands before putting them on and before taking them out. If you wear them often, it is best to buy a vibrating cleaner, which is very easy to use and has batteries. It only costs a dozen yuan to plant. If you clean it yourself, remember to rub it. Some care solutions will say that this product is very convenient and does not require rubbing. In fact, they are all lies. The cornea and metabolites left on the contact lens lenses must be washed away. To rub and clean, put the lens on your index finger, drop some care solution on it, rub it gently with your thumb and index finger, then rinse it again with care solution, put it in the lens case, and soak it in care solution. It is best to rinse it with care solution before taking it out for use next time. Personally, I recommend Haichang's water-like care solution and Aodi (Aodi has a long shelf life, up to half a year, and has a good sterilizing effect, while Haichang has a good moisturizing effect and is more comfortable to wear). Also, contact lenses and contact lenses must be checked regularly at an optical shop. If they are damaged or otherwise, wearing them will be uncomfortable and may damage the retina. You should also pay attention to the wearing time. It should not exceed 12 hours a day, and a maximum of 14 hours, otherwise you will have to have surgery to remove it. Authentic products are very important. Corneal staining and perforation are mostly caused by choosing inferior contact lenses, such as Bausch & Lomb, which all have contact lenses and can be purchased at optical stores. This is definitely more reliable.
