the eye drops do not indicate the ingredients, which infringes the consumer’s right to know
Yesterday afternoon, a reporter from Henan business daily visited several pharmacies in Zhengzhou and found that the outer package of some eye drops on sale did not indicate whether they contained “preservative” ingredients.
The instructions of some eye drops indicate that they contain benzalkonium chloride, ethyl hydroxybenzene, trichloro tert butyl alcohol, benzalkonium bromide, potassium sorbate and other ingredients. These are the “preservatives” often added in eye drops.
On December 24, Li Yingjie, a public welfare figure who is concerned about drug safety and a citizen of Zhengzhou, sent a proposal to the State Food and drug administration that “eye drops manufacturers should be ordered to modify the drug instructions to protect consumers’ right to know”.
Chang Boyang, a public welfare lawyer at Henan Asia Pacific people law firm, said that the practices of relevant enterprises “infringe upon consumers’ right to know. The State Food and drug administration has the responsibility to protect consumers’ right to know and safeguard public health.”

eye drops should not be used for a long time.
Xie like said that eye drops are a kind of surfactant. Even if they do not contain preservatives, long-term use will cause damage to eyes.
The State Food and Drug Administration said on its official Weibo that most eye drops in the domestic and foreign markets are allowed to add an appropriate amount of “bacteriostatic agents”, usually not more than 2 / 10000; As long as you follow the doctor’s advice and use it infrequently and for a long time, it will not hurt your eyes.
“Some eye drops may contain hormones in addition to preservatives.” An ophthalmologist of Zhengzhou people’s Hospital reminded that eye drops are special commodities and should be purchased and used under the guidance of professional doctors.
