Anti-smog eye drops are being snatched up like crazy, experts say tears can wash them away

　　Reference News Network reported on December 14 that Hong Kong media reported that smog has invaded China recently. Some online stores have taken the opportunity to launch eye drops or eye washes that claim to be able to combat smog and PM2.5. The prices range from 18 to 85 yuan, and one model has a monthly sales volume of over 100 yuan. However, clerks at many pharmacies in Xi'an, Shaanxi Province, said they had never heard of eye drops that could fight haze. Some experts even said that haze generally does not cause harm to the eyes.

　　According to a report on the Hong Kong Oriental Daily website on December 14, an online store recently sold four eye drops or eye washes that claim to be able to resist the harm of smog, and have received praise from many buyers. Later, some media in Xi'an sent reporters to visit five pharmacies on the streets, but the pharmacy clerks all said they had never heard of anti-haze eye drops.

　　Some ophthalmologists said that the human body can generally wash away fine particles through tears, blinking, etc., so haze usually does not harm the eyes, but PM2.5 is mainly more harmful to the human respiratory tract. He also reminded that it is best not to wear contact lenses in hazy days, because contact lenses will affect the normal metabolism of the corneal surface and hinder the discharge of particulate matter.
