Most cases of sore eyes improve within a few days using simple at-home care: lubricating drops, cool or warm compresses, and rest. The right treatment depends on what’s causing the soreness, which can range from digital eye strain and dry eye to infections and allergies. Here’s how to figure out what you’re dealing with and what to do about it.
Identify What’s Causing the Soreness
Sore eyes is a broad symptom, and the treatment that helps one cause can be useless (or worse) for another. A few clues can help you narrow it down before you reach for any drops or remedies.
Digital eye strain typically shows up as tired, aching eyes after prolonged screen use, sometimes with a mild headache. It affects both eyes equally and goes away with rest.
Dry eye feels like gritty, irritated eyes with a foreign body sensation. Both eyes are usually affected, and you may notice intermittent excessive watering, which is your eyes overcompensating for dryness.
Viral conjunctivitis (pink eye) starts in one eye and often spreads to the other. It causes diffuse redness, watery discharge, and a gritty discomfort. It’s highly contagious and generally resolves on its own within a few days to two weeks.
Bacterial conjunctivitis produces a thicker, yellowish or greenish discharge. A hallmark sign is waking up with your eyelids stuck together. You’ll feel a stinging sensation and a foreign body feeling in one or both eyes.
Allergic conjunctivitis is defined by intense itching. Both eyes water, turn red, and may produce a stringy, ropy discharge. It’s not contagious and tends to flare seasonally or around specific triggers like pet dander or pollen.
Corneal abrasion or foreign body causes sharp, severe pain usually in one eye, along with light sensitivity and heavy tearing. This needs prompt attention.
At-Home Treatments That Work
Compresses
A warm compress is one of the most effective home remedies for styes, blocked oil glands, and general eye fatigue. It takes about two to three minutes of sustained heat on the eyelid surface to soften clogged oil, so aim for five minutes per session. Two to four times a day is a good frequency. Don’t leave heat on continuously, though. Constant warmth dilates blood vessels in the area and can increase swelling.
A cool compress works better for allergic reactions, puffy eyelids, and general irritation. A clean washcloth soaked in cool water and placed gently over closed eyes for five to ten minutes can bring quick relief from itching and swelling.
Artificial Tears
Preservative-free lubricating drops are the single most versatile over-the-counter option for sore eyes. They provide brief symptom relief for nearly every type of surface eye irritation, from dry eye to mild strain to post-infection discomfort. If you use drops more than four times a day, preservative-free formulas are especially important because the preservatives in regular drops can irritate your eyes with frequent use.
Avoid drops marketed specifically to “get the red out.” These contain ingredients (tetrahydrozoline and naphazoline) that constrict blood vessels temporarily but can worsen redness and symptoms over time as your eyes become dependent on them. They treat how your eyes look, not how they feel.
The 20-20-20 Rule for Screen Strain
If your sore eyes are tied to computer or phone use, this simple habit makes a real difference: every 20 minutes, look at something 20 feet away for 20 seconds. This lets the focusing muscles in your eyes relax periodically throughout the day instead of staying locked in close-up mode for hours. Pair this with deliberate blinking. You blink far less often while staring at screens, which dries out your eyes faster.
Treating Allergy-Related Eye Soreness
If itching is the main symptom, over-the-counter antihistamine eye drops are your best bet. Look for combination drops that contain both an antihistamine and a mast cell stabilizer. The antihistamine component blocks the chemical (histamine) that triggers the itching, redness, and tearing. The mast cell stabilizer works differently: it prevents your body from releasing those chemicals in the first place, so it helps prevent symptoms from returning.
Ketotifen (sold as Alaway or Zaditor) is widely available without a prescription and falls into this dual-action category. If you need something stronger, olopatadine (Pataday) is another option in the same class. These are far more targeted than oral allergy pills for eye-specific symptoms, and they work faster on eye itching than a tablet you swallow.
When Antibiotics Are Needed
Most viral conjunctivitis clears up on its own without medication, much like a common cold. Bacterial conjunctivitis, however, sometimes requires prescription antibiotic drops or ointment. Your doctor is more likely to prescribe antibiotics if you have visible pus-like discharge, a weakened immune system, or if certain bacteria are suspected based on how aggressive the infection looks.
Antibiotics shorten the duration of bacterial infections, reduce the chance of complications, and help prevent spreading it to others. Signs and symptoms of most pink eye cases, whether viral or bacterial, generally improve within a few days to two weeks. The infection remains contagious as long as you have tearing and matted, crusty eyes.
Hygiene to Prevent Spreading and Reinfection
If your sore eyes are caused by an infection, hygiene is just as important as any drop or compress. The CDC recommends washing pillowcases, sheets, washcloths, and towels in hot water and detergent frequently during an eye infection, then washing your hands after handling those items.
Don’t share anything that touches your face or eyes: pillows, towels, washcloths, eye drops, contact lenses, or eye makeup. If someone in your household has pink eye, wash your hands after any contact with them or their belongings. Replace eye makeup (especially mascara and eyeliner) that you used while infected, since bacteria and viruses can survive on those products.
Contact Lens Wearers: Special Precautions
If your eyes become sore while wearing contacts, remove them immediately. Do not put them back in until your eye doctor says it’s safe. Wearing contacts over irritated or infected eyes traps bacteria against the cornea and can lead to bacterial keratitis, a serious corneal infection that threatens your vision.
If you wear daily disposables, throw away the pair you were wearing when symptoms started. For reusable lenses, thoroughly disinfect them before wearing again (or switch to a fresh pair if possible). Clean and replace your lens case as well, since cases are a common source of bacterial contamination.
Symptoms That Need Immediate Attention
Most sore eyes are harmless and temporary. But certain symptoms signal something more serious happening inside the eye. Get emergency care if your eye pain is severe and accompanied by a headache, fever, or pronounced light sensitivity. The same applies if your vision changes suddenly, you see halos around lights, or you experience nausea and vomiting alongside eye pain.
Other red flags include blood or pus coming from the eye, swelling in or around the eye, difficulty moving the eye or keeping it open, and any injury from a foreign object or chemical splash. Conditions like acute angle-closure glaucoma cause severe, throbbing pain with halos around lights and can permanently damage vision if not treated within hours. Iritis produces a constant, deep ache that radiates into the brow or temple and develops over hours. These are not wait-and-see situations.
