Taurine eye drops are mainly used for cataracts caused by disorders of taurine metabolism, and can also be used as an adjunctive treatment for acute conjunctivitis, herpetic conjunctivitis, and viral conjunctivitis. Taurine is a sulfur-containing amino acid, which is the main amino acid in the mature retina. Taurine eye drops can promote the growth and development of retina, relieve the spasm of ciliary muscle inside the eye, and can compete with reducing sugar in atrial water and vitreous humor to avoid glycation and oxidation of proteins in vitreous humor. When using this product, if congestion, eye itching and edema occur, you need to stop the drug immediately. Generally, you need to use it up within four weeks of opening, and if you can’t use it up, you need to throw it away. People who are allergic to taurine should not use this eye drop.
