There are five main types, and the right treatment depends on which one you have. Viral is the most common and usually clears on its own, bacterial is contagious and common in kids, and allergic isn't contagious. Toxic and nonspecific types come from irritation or a foreign object. A quick diagnosis matters.

Pink eye, or conjunctivitis, usually starts with a gritty, itchy feeling and redness in the white of your eye. You might also notice watery eyes, discharge, or crusty lashes in the morning. It spreads easily, so getting it diagnosed quickly helps you treat it and avoid passing it on.

Wash your hands often, avoid touching or rubbing your eyes, and don't share makeup, towels, or personal items. Clean and store contacts as directed, and replace eye makeup regularly. Good hygiene is the best defense, especially if someone nearby has it.

Allergic reactions, dry eyes, and blepharitis are often mistaken for pink eye because they cause similar redness and irritation. It’s important to get a proper diagnosis to determine the correct treatment, as pink eye treatments vary depending on the underlying cause.

The pink eye duration depends on the cause. Viral pink eye may last anywhere from a few days to two weeks, while bacterial pink eye can improve in a few days with treatment, usually lasting up to a week. Allergic pink eye typically subsides as the allergen is removed or managed.

Pink eye, or conjunctivitis, can spread through direct contact with infected individuals or surfaces. Children are particularly vulnerable because of close interactions at school. Pink eye can also develop from allergens or irritants, but these forms are not contagious.

Yes, viral and bacterial pink eye are highly contagious. Viral pink eye, spread through contact with tears or discharge, is especially common in children and can easily pass to others through shared items or close contact. To reduce the risk, avoid rubbing your eyes and practice good hygiene, like frequent hand washing and using clean tissues or cloths for your eyes.
