Abstract

The invention discloses a hard contact lens care solution. The hard contact lens care solution comprises 0.02 to 20 parts of a buffering agent, 0.01 to 10 parts of an osmotic pressure adjusting agent,0.001 to 30 parts of a clearing agent, 0.005 to 1.0 part of a disinfectant, and 0.02 to 20 parts of a tackifier. The hard contact lens care solution can be used for cleaning, washing, disinfecting, lubricating, moisture retention, immersing, and storage of hard contact lens with high efficiency, is capable of prolonging service life of lens, maintaining the vision definition after wearing glasses, and reducing complication caused by wearing of contact lens.

Description

technical field [0001] The invention relates to the technical field of contact lenses, in particular to a hard contact lens care solution. Background technique [0002] The common contact lenses currently on the market are mainly used to correct vision, protect the eyeball or increase the beauty of the eyes. According to their material properties, they are divided into hydrophilic contact lenses and non-hydrophilic contact lenses, also known as soft contact lenses and hard contact lenses. mirror. Soft contact lenses are made of polymer materials with many hydrophilic chemical groups, and generally have the characteristics of high water content, surface hydrophilicity, and are easily affected by the environment and pollutants, and pollutants, especially organic molecules, are easy to penetrate into In the lens material matrix, there are deposits in the lens and on the surface of the lens. Rigid contact lenses generally have the following characteristics due to the material ...
