The invention provides a
contact lens preserving fluid and a preparation method thereof, and belongs to the technical field of contact lenses. The
contact lens preserving fluid is prepared from the following components in parts by
mass: 1 to 5 parts of
Ectoine, 0.3 to 4 parts of
schizophyllan, 0.05 to 0.3 part of
humectant, 0.3 to 1.2 parts of pH (Potential of
Hydrogen)
regulator, 0.5 to 1.5 parts of
osmotic pressure regulator, 0.1 to 2 parts of chelating agent, 0.1 to 3 parts of surfactant and 90 to 98 parts of water. The preserving fluid disclosed by the invention can be used for solving
dry eyes, relieving
eye fatigue, improving the lubricating and moisturizing effects, eliminating
inflammation, improving the antibacterial ability and improving the wearing comfort of contact lenses; the
humectant and Ectoin are combined, so that the
contact lens preserving fluid has good hydrophilicity, stability and
adhesive force, and the moisturizing effect of the contact lens preserving fluid is prolonged; the
schizophyllan has the effects of enhancing
immunity, preserving
moisture, resisting oxidation and the like.
