Corneal contact lens polishing solution and preparation method thereof

The invention relates to a corneal contact lens polishing solution which comprises the following components in parts by weight: 10-30 parts of inorganic polishing powder, 0.5-5 parts of dispersing agent, 1-15 parts of thickening agent, 10-30 parts of moistening agent, 0.1-5 parts of surfactant and 100 parts of water. A preparation method of the corneal contact lens polishing solution comprises the following steps: (1) putting 100 parts by weight of hot water into a beaker, adding 10-30 parts by weight of inorganic polishing powder and 0.5-5 parts by weight of dispersing agent into the hot water, and stirring and dispersing till the water temperature is reduced to be the room temperature, so as to obtain suspension; (2) adding 1-15 parts by weight of thickening agent into the suspension, and stirring till the thickening agent is completely decomposed so as to obtain a mixture solution; (3) adding 10-30 parts by weight of moistening agent and 0.1-5 parts by weight of surfactant into the mixture solution of the step (2) at one time, and continuing stirring till a uniform mixture solution is obtained, that is, the high-performance polishing solution for hard contact lenses.
