Is it harmful to use too much Hailu eye drops?

Hailu sodium hyaluronate eye drops can be used for a long time without toxic side effects. At present, the common eye drops on the market contain preservatives, which are toxic after long-term use, because preservatives will reduce the activity of corneal conjunctival epithelial cells, cause corneal conjunctival damage and cause inflammation. Hailu sodium hyaluronate eye drops are imported from Germany. In order to preserve the eye drops for a long time without adding preservatives, the German company Usfama adopted a unique patented COMOD packaging system on the sea dew, which ensured the absolute isolation of the eye drops from the outside air. Therefore, Hailu is also the only preservative-free multi-dose sodium hyaluronate eye drops on the market, which is safe and secure to use, which is significantly different from most eye drops on the market.
