Bacterial Eye Infection – What You Need to Know

Got a red, gooey eye that hurts when you blink? Chances are you’re dealing with a bacterial eye infection, also called bacterial conjunctivitis. It’s one of the most common eye problems, especially in busy households or schools where germs spread easily. The good news? Most cases clear up quickly with the right care.

Common Signs to Spot Early

When bacteria invade the thin membrane covering your eye (the conjunctiva), they cause inflammation. Look for these tell‑tale signs:

• Redness that starts at the inner corner and spreads outward.
• Sticky discharge – often yellow, green, or white, and it can crust over overnight.
• Itching or burning sensation, especially after waking up.
• Tearing that feels more like a constant stream than occasional drops.
• Sensitivity to light – bright rooms may make your eye ache.

If you notice any of these, wash your hands, avoid touching the eye, and consider seeing a pharmacist or doctor. Early treatment stops the infection from spreading to the other eye or to people around you.

How to Treat and Prevent

Most bacterial eye infections respond well to antibiotic eye drops or ointments. You can get these with a prescription, but some pharmacies sell over‑the‑counter options for mild cases. Follow the dosing schedule exactly – usually one drop several times a day for a week. Skipping doses or stopping early can let bacteria bounce back.

While the meds work, help your eye heal faster with these simple steps:

• Clean the eye gently with a warm, damp cloth. Use a fresh part of the cloth for each wipe.
• Avoid contact lenses until the infection clears. Switch to glasses to keep your eye comfortable.
• Don’t share towels, pillows, or eye makeup. Bacteria love a good ride to a new host.
• Keep hands clean. Wash with soap for at least 20 seconds before and after touching your eyes.

Prevention is mostly about hygiene. Encourage kids to wash hands after playing outside, and clean shared surfaces like doorknobs regularly. If you wear makeup, replace mascara every three months and discard any eye products that look discolored.

Most people feel better within 2‑3 days of starting antibiotics, but the full course is usually 7‑10 days. If symptoms linger past a week, or if you experience severe pain, vision changes, or intense swelling, seek medical help right away. Those could be signs of a more serious condition.

Bottom line: a bacterial eye infection is annoying, but it’s manageable. Spot the signs early, use prescribed drops as directed, keep everything clean, and you’ll be back to clear vision in no time.
