Red Eye Treatment: What Works, What Doesn't, and What to Avoid

When your eye turns red, it’s not just annoying—it’s a signal. Red eye, a common symptom caused by irritation, infection, or underlying health issues. Also known as bloodshot eye, it’s not a disease itself but a warning sign that something’s off in your eye or body. Many people reach for over-the-counter drops without knowing why their eye is red. That’s like taking painkillers for a fever without checking for infection. The truth? Not all red eyes are the same. Some are harmless and clear up in a day. Others need real medical attention.

Conjunctivitis, an inflammation of the thin membrane covering the white part of the eye. Also known as pink eye, it’s one of the most common causes of red eye. It can be viral, bacterial, or allergic. Viral conjunctivitis often comes with a cold and clears on its own. Bacterial conjunctivitis needs antibiotic eye drops—no ifs, ands, or buts. Allergic red eyes? They itch, water, and flare up around pollen or pet dander. You won’t fix those with antibacterial drops. Then there’s dry eyes, a condition where your eyes don’t make enough tears or the tears evaporate too fast. It’s more common than you think, especially if you stare at screens all day. People mistake dry eyes for infection and use the wrong drops, making things worse. Glaucoma, uveitis, and even high blood pressure can also cause red eyes. These aren’t DIY fixes. Ignoring them can cost you vision.

What you do matters. Rubbing your eye? Bad idea. Sharing towels? Don’t. Using old or someone else’s eye drops? Dangerous. Even some "redness-relief" drops can cause rebound redness if you use them too long. The right treatment starts with knowing the cause. A simple exam by a professional can tell you if it’s a virus, allergy, or something more serious. And yes—sometimes your red eye is linked to something deeper, like an autoimmune condition or a reaction to medication.
