Eye Infection: Symptoms, Causes, and Treatment

Some eye infections are serious and can damage your eyes if you ignore them. Plenty of others are common, easy to treat, and even easier to avoid. If you think you have an eye infection, or your eyes just do not feel right, it is a good idea to see your eye doctor. 

What are the most common eye infections? 

Styes: stye shows up when bacteria build up in the glands along your eyelid, leaving what looks like a small pimple on the lid. They tend to hurt, feel bigger than they look, and make your eyes water. Resist the urge to pop one, since that usually makes things worse. Use a warm compress to ease the pain and pressure instead. Keep the area clean and skip makeup and contacts until it clears up. 

Conjunctivitis: Better known as pink eye, this is inflammation of the lining of the eye caused by a virus, bacteria, or allergens. It often leaves the eye red and swollen with extra pus and mucus, and it can be itchy and sore. Viral and bacterial pink eye spread easily, so wash your hands often and keep your distance from others while you have it. If it does not ease up, check in with your eye doctor. 

BlepharitisThis is inflammation of the eyelids, and it can come from bacteria, clogged oil glands, or tiny mites along the lash line. It leaves your eyes and eyelids red, itchy, and irritated, sometimes with blurry vision or the feeling that something is stuck in your eye. Sleeping in makeup or rubbing your eyes with dirty hands makes it more likely. A warm compress and gentle eyelid cleaning usually help, though you may need your eye doctor's help if it sticks around. 

How are eye infections treated? 

Eye infections tend to bring some mix of discharge, redness, pain, itching, swelling, watery eyes, blurry vision, dry eye, and light sensitivity. A few things you can try at home: 

  • Wash your eyes and eyelids with a doctor-recommended cleanser, or a mix of warm water and a little hypoallergenic baby shampoo, to clear out oil, bacteria, and pollen. 

  • Hold a warm compress over your eyes to ease swelling and pain. 

  • Lay a warm, damp washcloth over your eyes before bed to soothe them. 

Tips for Preventing Eye Infections 

A few simple habits go a long way toward keeping infections away. Most of these are common sense, but they are worth repeating, and worth teaching the younger members of your family. 

  • Wash your hands before touching your eyes. 

  • Try not to rub your eyes. 

  • Do not share cosmetics with others. 

  • Replace cosmetics and applicators if you develop an infection. 

  • Stay away from tobacco smoke, chemical fumes, and other irritants. 

  • Take your makeup off before bed. 

  • Keep your contacts and case clean, just as your eye doctor tells you. 

  • Do not sleep in your contacts. 

  • Swap your contact case every three months. 

  • Keep your bedding, towels, and clothing clean. 

The good news is that most common eye infections clear up on their own without treatment. But if your symptoms last longer than 7 to 10 days or suddenly get worse, see your eye doctor as soon as you can. That can be a sign of something more serious that needs a professional's attention.
