What is Pink Eye?
Conjunctivitis — better known as pink eye — is inflammation of the clear membrane (conjunctiva) that covers the white part of your eye and lines your eyelids. That red, irritated, gunky eye? That's your body's inflammatory response in action.
Three types of pink eye: Viral pink eye is the most common and self-limiting — it'll clear on its own. Bacterial pink eye causes thick yellow or green discharge and needs antibiotic drops. Allergic pink eye happens when your immune system overreacts to allergens like pollen or pet dander.
Not all pink eye needs prescription drops. Viral pink eye clears on its own, just like a cold. Bacterial pink eye — the kind with thick yellow/green discharge — that's where antibiotic drops come in.
Symptoms: What to Look For
Pink eye shows up pretty consistently. Here's what to watch for:
Redness
Redness in one or both eyes — sometimes just the white part, sometimes spreading to the eyelids.
Itching & Burning
Your eyes feel like they're on fire. The urge to rub them is intense (but don't — it spreads the infection).
Gritty Feeling
Your eye feels like there's something in it, even when there isn't. That scratchy, uncomfortable sensation.
Discharge
Watery and clear = likely viral. Thick yellow or green = likely bacterial. Either way, it's annoying.
Morning Crusting
Your eyelids stick together when you wake up. You may need to gently rinse with warm water to open them.
Excessive Tearing
Your eyes water constantly. Sometimes it's hard to tell if it's tears or discharge.
Light Sensitivity
Bright light bothers you more than usual. Sunglasses help, but it's usually temporary.
Viral vs Bacterial vs Allergic
| Type | Discharge | Contagious? | Treatment |
|---|---|---|---|
| Viral | Watery, clear, or mild | Yes, very. 7-14 days. | Time + home care. No drops needed. |
| Bacterial | Thick, yellow, or green | Yes, very. 24 hrs on drops. | Antibiotic eye drops (usually 5-7 days) |
| Allergic | Watery, itchy | No, not contagious | Antihistamine drops + avoid trigger |
Treating Pink Eye
If your pink eye is viral, we may not prescribe anything — it'll clear up on its own in 7-14 days. Antibiotic drops only work on bacterial pink eye.

Good news: Most antibiotic eye drops are inexpensive and work quickly. Many people see improvement within 24 hours of starting treatment. You'll probably feel way better after the first day.
Red Flags: When to Seek Help
- Severe eye pain that doesn't improve with time
- Significant vision changes or blurriness
- Intense sensitivity to light (beyond mild discomfort)
- Symptoms worsening after 48 hours on antibiotic drops
- Swelling around the eye (not just redness)
- Only one eye affected with severe pain (could be something else)
Home Care: What Works
While antibiotic drops handle the infection, home care helps manage the discomfort and speeds recovery.
Warm vs Cold Compresses
Bacterial pink eye: Warm compresses feel better and help loosen discharge. Allergic pink eye: Cool compresses reduce itching and inflammation. Apply gently for 5-10 minutes, 2-3 times daily.
Gentle Discharge Cleaning
Use a damp, clean cloth to gently wipe away crusting or discharge from the outer corner of your eye toward your nose. Use a fresh cloth for each eye to avoid spreading infection.
Don't Touch or Rub
I know it's hard, but touching your eyes spreads infection and makes inflammation worse. Keep your hands away. Seriously.
Wash Hands Constantly
Wash after touching your face, after applying drops, and before touching anything else. Use soap and warm water for at least 20 seconds.
Don't Share Personal Items
Use your own towels, pillows, and pillowcases. Don't share eye makeup, contacts, or contact lens cases. Bacteria and viruses survive on these items.
Remove Contacts
Switch to glasses immediately. Contacts trap bacteria against your eye and make it worse. You can go back to contacts once symptoms are completely gone.
Throw Away Eye Makeup
Any eye makeup used before the infection should be thrown away. Mascara, eyeliner, eyeshadow — all of it. Bacteria and viruses live on makeup. Get new products once you're better.
How Contagious is Pink Eye?
Here's the deal: viral and bacterial pink eye are VERY contagious. Allergic pink eye is not contagious at all.
How Long You're Contagious
Viral: 7-14 days. Bacterial: about 24-48 hours after starting antibiotic drops. Once you start treatment and symptoms improve, you're usually safe.
School & Work
For bacterial pink eye with antibiotics: stay home the first day, return after 24 hours on drops. For viral: stay home until symptoms improve significantly (usually 3-5 days). Check your school or employer's policy.
Spread Prevention
Don't share towels, pillows, eye makeup, or personal items. Wash your hands after touching your face. Don't share contacts or glasses. Cover your face when coughing or sneezing.
