A bottle of Visine eye drops

Visine is a brand of over-the-counter eye drops produced by Johnson & Johnson. It is commonly used to relieve redness and minor eye irritation. Visine contains the active ingredient tetrahydrozoline, which is a vasoconstrictor.

Uses[edit | edit source]

Visine is primarily used to alleviate ocular redness caused by minor irritants such as dust, smoke, chlorine, and allergens. It works by constricting the superficial blood vessels in the conjunctiva, thereby reducing redness and swelling.

Mechanism of Action[edit | edit source]

The active ingredient in Visine, tetrahydrozoline, is an alpha-adrenergic receptor agonist. It acts on the alpha-adrenergic receptors in the blood vessels of the eye, causing them to constrict. This vasoconstriction reduces blood flow to the superficial vessels, leading to decreased redness and swelling.

Side Effects[edit | edit source]

While Visine is generally safe for short-term use, it can cause side effects such as:

Prolonged use can lead to tolerance and dependence, where the eyes become reliant on the drops to maintain normal appearance.

Precautions[edit | edit source]

Visine should not be used for more than 72 hours without consulting a healthcare professional. It is not recommended for individuals with glaucoma, as it can increase intraocular pressure.

Alternatives[edit | edit source]

Other treatments for eye redness and irritation include:
