Pink eye (conjunctivitis) is one of the most common and most contagious eye conditions, affecting millions of people each year. It’s also one of the most frequently mistreated — because the right approach depends entirely on what’s causing it. Viral pink eye needs to run its course. Bacterial pink eye needs prescription antibiotic drops. Allergic pink eye needs antihistamines. Using the wrong treatment doesn’t just waste time — it can delay recovery and in the case of bacterial conjunctivitis, allow the infection to worsen.
The Three Types of Pink Eye: How to Tell Them Apart
Viral Conjunctivitis
The most common type, usually associated with adenovirus — the same virus behind the common cold. Signs: redness in one or both eyes, watery discharge (not thick or pus-like), burning or irritation, and often an accompanying cold or upper respiratory infection. Highly contagious. Does not respond to antibiotics. Typically resolves on its own within 7–14 days.
Bacterial Conjunctivitis
Caused by bacteria such as Staphylococcus aureus or Streptococcus pneumoniae. Signs: thick, yellow-green discharge that crusts the eye shut (especially in the morning), redness, and sometimes a gritty or sticky sensation. Often affects one eye first but can spread to both. Requires antibiotic eye drops or ointment — it does not resolve reliably without treatment. Also contagious.
Allergic Conjunctivitis
Triggered by allergens — pollen, pet dander, dust mites, or contact lens solutions. Signs: intense itching (the defining symptom), redness, watery or stringy discharge, and often accompanying sneezing or nasal symptoms. Not contagious. Responds to antihistamine eye drops and allergen avoidance.
Home Treatment for Each Type
For Viral Pink Eye
There’s no antiviral treatment for common viral conjunctivitis — the goal is comfort while your immune system clears the infection. Apply a cool, damp cloth to closed eyes for relief from irritation. Preservative-free artificial tears (available OTC) can help flush the eye and reduce discomfort. Avoid contact lenses until fully resolved. Wash hands frequently and avoid touching your eyes to prevent spreading to the other eye or to other people.
For Bacterial Pink Eye
OTC remedies won’t clear a bacterial infection. You need prescription antibiotic eye drops. Gently clean away discharge with a warm, damp cloth before applying any drops. Keep hands clean and avoid sharing towels, pillowcases, or anything that contacts the eye. Children typically need to be kept home from school or daycare until they’ve been on antibiotics for 24 hours.
For Allergic Pink Eye
OTC antihistamine eye drops such as ketotifen (Zaditor, Alaway) are effective for allergic conjunctivitis. Oral antihistamines like cetirizine (Zyrtec) or loratadine (Claritin) can also help. Cool compresses reduce inflammation and discomfort. Identifying and reducing exposure to the triggering allergen is the long-term solution.
Why the “Last Place You Want to Go” Problem Is Real
Pink eye is notoriously contagious. Taking a child or yourself to a waiting room full of other patients when you have active bacterial or viral conjunctivitis — or exposing yourself to additional pathogens when your eye is already compromised — is the last thing you want. This is one of the most logical use cases for a house call: a condition that needs clinical evaluation and potentially a prescription, but where going out is both miserable and actively spreads illness.
How Sickday Handles Pink Eye
Sickday’s licensed clinicians can come to your home, office, or hotel in NYC — typically within 90 minutes — and evaluate your eye in person. During the visit, your clinician will assess the discharge type, look for signs that differentiate viral from bacterial conjunctivitis, and determine whether antibiotic eye drops are clinically appropriate. If so, the prescription is sent to your pharmacy immediately. If the presentation is viral, you’ll leave the visit with a clear treatment plan (and reassurance about the timeline) rather than an unnecessary antibiotic prescription.
Red Flags That Need Urgent Evaluation
Most cases of pink eye are uncomfortable but not dangerous. However, certain symptoms warrant prompt in-person evaluation: significant eye pain (not just irritation), sensitivity to light (photophobia), blurred vision that doesn’t clear when you blink, very intense redness, or symptoms that worsen rapidly rather than gradually improving. These can occasionally signal a more serious condition such as keratitis or uveitis.
Frequently Asked Questions
How contagious is pink eye?
Viral and bacterial conjunctivitis are both highly contagious — spread through direct contact with discharge, shared items, or touching contaminated surfaces and then touching your eye. Strict hand hygiene and avoiding shared items are essential. Allergic conjunctivitis is not contagious.
Can I tell if it’s viral or bacterial without seeing a clinician?
Often, but not always. Thick, pus-like yellow-green discharge is strongly associated with bacterial conjunctivitis. Watery discharge alongside cold symptoms strongly suggests viral. But the distinction isn’t always clear-cut, and misidentifying the type means using the wrong treatment. A clinician can make the call definitively.
How long does pink eye last?
Viral conjunctivitis typically resolves in 7–14 days without treatment. Bacterial conjunctivitis usually clears within 3–5 days with antibiotic eye drops. Allergic conjunctivitis persists as long as allergen exposure continues.
Can I wear contact lenses with pink eye?
No. Stop wearing contact lenses at the first sign of conjunctivitis and don’t resume until the infection has fully cleared and your clinician confirms it’s safe. Wearing contacts with pink eye significantly increases the risk of complications.
Do I need a prescription to treat pink eye?
For bacterial conjunctivitis, yes — antibiotic eye drops require a prescription. For viral and allergic pink eye, OTC options and supportive care are typically sufficient, though a clinical evaluation is still useful to confirm the type.
