Chondroitin sulfate has a protective effect on corneal collagen fiber,

Promote the growth of fibers in the matrix, enhance permeability, improve blood circulation, accelerate metabolism, promote the absorption of osmotic fluid and the elimination of inflammation; Its polyanion has a strong water retention, can improve the corneal tissue water metabolism, has a strong affinity to the cornea, can form a layer of air permeability and water retention film on the corneal surface, improve the symptoms of dry eyes. By promoting the formation of matrix, it provides a framework for the migration of cells, which is conducive to the migration of corneal epithelial cells, so as to promote the healing of corneal trauma, the absorption of exudate and the elimination of inflammation.
