Eyeglasses care solution: Contact lens care solution is a colorless and transparent liquid, which consists of sodium chloride and preservatives. It has the functions of nursing, cleaning, disinfection, storage, washing, moisturizing and deproteinization. Early contact lens care solutions are divided into three types, one is contact lens disinfectant, the other is contact lens cleaning solution, and the other is contact lens comfort solution. It is quite inconvenient to use. After taking off the lens, drop the cleaning liquid on the lens, gently rub the lens with your fingers, rinse it off, and then soak the lens in disinfectant for preservation. The next day, after wearing glasses, according to the discomfort of the eyes, the comfort liquid was irregularly dropped. But this kind of care is not convenient enough after all.

This nursing liquid integrates the cleaning, disinfection and comfort functions of lenses. Although the use and maintenance procedures of lenses are the same as before, it is very convenient to use a liquid.
