Visine (/ˌvaɪˈziːn/), also known as Vispring, is a brand of eye drops produced by Johnson & Johnson. Visine was first introduced in 1958 and was bought by Pfizer in 1999. In 2006, Johnson & Johnson acquired Visine, along with Pfizer's entire consumer healthcare portfolio. The original formulation of Visine includes the active ingredient tetrahydrozoline hydrochloride, which is a vasoconstrictor that constricts the eye's superficial blood vessels to temporarily reduce eye redness. In addition to its original formulation, Visine is available in several varieties of eye drops for different types of eye irritation. These include formulas with antihistamines for allergy-induced irritation, to moisturizing formulations for eye dryness. These formulations use active ingredients ranging from oxymetazoline to naphazoline. Some Visine products cater specifically to contact lens wearers or to those who require artificial tears.
