Everything to Know About Pink Eye

It’s common, it’s contagious, and it can look alarming even when it’s mild. Here’s what you need to know if you or someone in your family wakes up with a red, irritated eye.

Pink eye, or conjunctivitis, is inflammation of the conjunctiva, the thin, clear tissue that covers the white part of the eye and lines the inside of the eyelid. When this tissue becomes irritated or infected, blood vessels swell and become more visible, giving the eye its telltale pink or red appearance.

There are three main types of pink eye, and knowing which one you have matters for treatment.

• Viral conjunctivitis is the most common form. It often accompanies a cold or upper respiratory infection and is highly contagious. It usually causes watery discharge and can affect one or both eyes.
• Bacterial conjunctivitis tends to produce thicker, yellow or green discharge that can cause the eyelids to stick together, especially after sleep. It’s also contagious and typically requires antibiotic eye drops.
• Allergic conjunctivitis isn’t contagious at all. It’s triggered by allergens like pollen, pet dander, or dust, and usually comes with itching, tearing, and swelling in both eyes at once.

While symptoms vary by type, most cases of pink eye involve some combination of redness, itching or burning, discharge, tearing, swollen eyelids, and a gritty feeling in the eye. If you experience significant pain, vision changes, or sensitivity to light, seek care right away, as these can signal a more serious issue.

Viral and bacterial pink eye spread easily through direct contact with eye discharge, whether that’s from touching your eyes and then touching another surface, sharing towels or pillowcases, or close contact with someone who’s infected. Good hand hygiene and avoiding shared items go a long way in preventing spread, especially in schools and workplaces.

Treatment depends on the cause. Viral pink eye typically resolves on its own within one to two weeks and is managed with cool compresses and artificial tears for comfort. Bacterial pink eye usually responds well to prescription antibiotic drops or ointment. Allergic conjunctivitis often improves with antihistamine eye drops and by limiting exposure to the trigger. It’s worth noting that pink eye is one of the most overtreated conditions in eye care. Many people assume they need antibiotics regardless of cause, but using the wrong treatment won’t help and may delay proper healing.

Not every case of pink eye needs a same-day appointment, but you should be seen promptly if you have significant eye pain, blurred vision, intense redness, a lot of discharge, or symptoms that don’t improve after a few days. Contact lens wearers should always have red or irritated eyes evaluated, since certain infections in this group can become serious quickly.

Pink eye is common and usually not dangerous, but getting the right diagnosis matters. If you’re dealing with a red, irritated eye, don’t guess. Schedule a visit so we can determine the cause and get you the right treatment to feel better fast.
