What Is Visine?
Visine is a brand of eye drops originally distributed by Pfizer, but is now produced by Johnson & Johnson. Visine is available at your local drugstore or grocery store, and is used to treat eye irritation. Unlike most other eye drops, Visine does not claim to actually soothe the eye. Visine is mainly a product for people who get red, bloodshot eyes and would like to limit their appearance. If you have a serious eye condition, see an ophthalmologist. Do not let an eye condition go untreated, as it could be serious. Do not treat pink eye or other contagious diseases with Visine. Visine is not a medication--it is only a cosmetic remedy.
How Does Visine Work?
The two active ingredients of Visine are tetrahydrozoline hydrochloride and potassium chloride. Tetrahydrozoline hydrochloride is a vasoconstrictor, causing blood vessels to constrict. If you have red, bloodshot eyes, the blood vessels in your eyes are irritated, or the level of blood in the vessels in your eyes are pumping a larger amount of blood than usual. By putting several drops of Visine in your eyes, the tetrahydrozoline hydrochloride will constrict the blood vessels in your eyes, making them not as visible. Visine does not help any medical conditions, so do not use Visine if you have red eyes due to an irritation or infection.
Other Uses for Visine
Visine, with its vasoconstrictive properties, is also effective for use on red marks on the skin. If you have a pimple or red blotch that is particularly noticeable, soak a cotton ball in Visine and apply to the affected area for a minute. The anti-reddening results may not last long, but will provide you with a temporary fix for any red spots on your face. It is a rumor that putting a few drops of Visine will cause a person to have diarrhea. Ingesting Visine, however, can make a person violently ill. If you ingest Visine accidentally, consult Poison Control immediately.
