For contact lenses, the care solution should be the most important and necessary accessory product. Basically, except for the time when it is worn on the eyes, contact lenses always deal with the care solution. It can be said that the contact lens care solution is the one that has the most contact with the lens for the longest time. In fact, the role of the care solution is not only to provide a sterile environment for the lens, but more importantly to keep it moist and maintain a soft state, thereby extending the life of the lens.
If a simple classification of care solution, it can be roughly divided into two types of multi-functional care solution and hydrogen peroxide care solution. Multi-functional care solution is our common current-selling contact lens care solution, which integrates functions of moisturizing, sterilization, disinfection, and protein removal. It is mainly used to clean and maintain contact lenses; while hydrogen peroxide solution has stronger sterilization ability , But it needs sufficient time to neutralize the reaction, otherwise it is easy to produce irritation and burn the cornea.
For silicone hydrogel contact lenses, general multifunctional care solution can be used for normal care. However, silicone hydrogels are more prone to bacteria growth due to their material properties. Therefore, in order to avoid lens contamination, when buying a care solution, you should focus on the role of sterilization and disinfection, but you must also consider the moisturizing effect, and you can also use hydrogen peroxide and multi-functional care The liquid is used together to obtain better care effect.
Compared with traditional hydrogel materials, silicon hydrogels have higher oxygen permeability and water content, which enhances the wearing experience, so in order to ensure wearing comfort, the choice of care solution becomes very important. What needs to be emphasized is that you should never soak and clean the lens with liquids other than the care solution at any time to avoid eye infections.
