The warmth and beauty of spring can lead to itchy eyes. So can infection and other conditions. The good news is they usually aren’t a sign of something serious. Here’s what you need to know.
- Outdoor substances: Pollen from trees, grasses, weeds, and shrubs
- Indoor substances: Dust mites, fungus, mold, and tiny bits of pet skin (pet dander)
- Man-made substances: Tobacco smoke, perfume, chemicals, and exhaust fumes
Infection: The most common one is pinkeye, or conjunctivitis. That just means inflammation of the conjunctiva, or the inner lining of the eye. Anyone can get it, but it happens most often in children. Your eyes may be red and swollen. Pus might make your eyelids stick together while you’re asleep. Bacteria usually cause pinkeye that has a discharge. In rare cases, a virus can do it, too. Allergies can sometimes inflame the conjunctiva. That’s more likely to cause mucus, not pus.
Blepharitis. That’s inflammation of the eyelids. It happens when tiny oil glands at the base of your eyelashes get clogged. Your eyes might be red and irritated. It can be hard to get rid of, but it’s not contagious and typically doesn’t affect your eyesight. Allergies, or skin conditions like acne or dermatitis, can make it worse.
Foreign substance. A bit of grit or sand caught under the eyelid is enough. If antibiotic eyedrops don’t help a suspected infection, then it could be a bit of dirt in your eye.
Contact lenses. Sometimes your eyes can’t tell your contacts are supposed to be there. So they treat them like a foreign substance. It might be because they don’t fit the right way. You’ll probably notice this right after you put them in. Contact lenses can also trap grit or germs that lead to infection. Regularly cleaning and changing your contact lenses can help.
Corneal ulcers. Your doctor might call this keratitis. Very dry eyes, an injury, or an infection could lead to small sores, or ulcers, on the cornea. That’s the clear lens that covers the front of your eye. They can irritate your eye and cause pus and crustiness.
Symptoms of itchy eyes include:
The doctor will ask questions about your medical history and symptoms. They’ll also look at your eyes closely. In some cases, they might take a small sample of fluid, pus, or other material from the eye to test for bacteria.
A clean, cool washcloth might soothe itchy eyes for a while. Use a clean, warm washcloth to soften and gently wipe away pus or eye boogers. Be sure to wash your hands after so you don’t spread an infection if you have one.
That might be all you need for mild itching. Even some infections, like certain types of pinkeye, often clear up on their own without medication. If you have allergies, try to avoid the trigger substance. Take allergy medication like pills or eyedrops.
If your itching is more serious, options might include:
- Saline solution to flush grit or dirt from your eye
- Antibiotic drops to kill the bacteria causing an infection
- Steroid drops to lessen inflammation and ulcers
- Surgery to remove a foreign object or fix an injury
Here are a few ways to ward off itchy eyes:
Try not to touch your eyes. It can be tempting to rub your eyes when they’re itchy, especially during allergy season. That could irritate them more and could even scratch the surface of your eye. Take allergy medication if it helps with the itch.
Wash off your makeup. Do it each night before you go to bed so it won’t block pores and hair follicles. It’s also a good idea to get rid of makeup after about 6 months to avoid spreading bacteria. Don’t share your makeup with other people.
Be careful with contact lenses. Talk to your eye doctor about the best way to disinfect and clean them. Wash your hands thoroughly before you handle them. Tell the doctor right away if your lenses seem to make your eyes itch.
