Overview
Pink eye, also called conjunctivitis, is one of the most common eye conditions. It happens when the clear tissue that covers the white part of your eye becomes inflamed. This tissue is called the conjunctiva.
Pink eye affects millions of people each year. Children get it more often than adults, especially in schools and daycares where germs spread easily. The condition gets its name because the white part of your eye turns pink or red when inflamed.
While pink eye is usually not serious, it can be very uncomfortable. Some types spread easily from person to person. Knowing the signs and proper treatment helps you get better faster and avoid spreading it to others. Understanding the difference between stye vs pink eye can help identify what's causing your eye irritation.
Most people recover from pink eye within one to two weeks with proper care. The inflammation goes away as your body fights the infection or irritation. Getting medical help early can make symptoms less severe and reduce how long you feel uncomfortable.
Symptoms & Signs
Pink eye symptoms can vary depending on what's causing the inflammation. Most people notice changes in how their eyes look and feel within a few days of exposure.
Primary Symptoms
Red or pink coloring in the white part of one or both eyes
Watery or thick discharge that may be clear, yellow, or green
Itching or burning sensation that makes you want to rub your eyes
Gritty feeling like there's sand or dirt in your eye
Sensitivity to light that makes bright lights uncomfortable
Crusty eyelashes especially when you wake up in the morning
Swollen eyelids that may make your eyes look puffy
When to Seek Care
See a healthcare provider if you have severe eye pain, vision changes, or very bright light hurts your eyes. You should also get medical care if symptoms get worse after 2-3 days or don't improve after a week.
Your eyes might feel scratchy or uncomfortable when you blink. Some people feel like something is stuck in their eye even when nothing is there. These feelings usually go away as the pink eye heals.
When to Seek Immediate Care
Get emergency care right away if you have severe eye pain, sudden vision loss, or signs of serious infection like fever with eye symptoms.
Causes & Risk Factors
Pink eye has several different causes. The type of pink eye you have affects how it's treated and whether it spreads to others.

Diagnosis
Healthcare providers can usually diagnose pink eye by looking at your eyes and asking about your symptoms. They'll want to know when symptoms started and what might have caused them.
Medical History & Physical Examination
Your doctor will ask about recent cold symptoms, allergies, or exposure to people with eye infections. They'll examine both eyes with a bright light to check the color and amount of discharge. The doctor will also look at your eyelids and the area around your eyes for swelling or other signs.
Diagnostic Testing
Visual examination to check eye color, discharge, and swelling patterns
Culture test if bacterial infection is suspected or symptoms are severe
Allergy testing when allergic pink eye is suspected and symptoms keep returning
Tear sample analysis in cases where the cause isn't clear from examination
Treatment Options
Treatment for pink eye depends on what's causing it. The goal is to reduce symptoms and prevent spreading the infection to others.
Conservative Treatments
Cool compresses applied to closed eyes for 5-10 minutes several times daily
Artificial tears to wash away irritants and keep eyes moist
Gentle eye cleaning with warm water and clean cloths to remove discharge
Avoiding contact lenses until symptoms completely clear up
Hand washing frequently to prevent spreading infection
Advanced Treatments
Antibiotic eye drops or ointments for bacterial pink eye when prescribed by a doctor
Antihistamine eye drops for allergic pink eye to reduce itching and swelling
Anti-inflammatory medications in severe cases to reduce pain and inflammation
Your doctor might prescribe different medicines depending on whether a virus, bacteria, or allergy is causing your pink eye. Some drops work best when used several times a day. Always use them exactly as your doctor tells you to get the best results.
Living with the Condition
Managing pink eye at home focuses on comfort and preventing the spread of infection. Most people can continue normal activities with some precautions.
Daily Management Strategies
Keep your hands clean by washing them frequently with soap and water. Use separate towels and pillowcases to avoid spreading infection to family members. Clean your glasses more often if you wear them, and throw away any eye makeup used before symptoms started. Avoid rubbing your eyes even if they itch, as this can make symptoms worse and spread infection.
Wear sunglasses when you go outside if bright light bothers your eyes. Take breaks from looking at screens and computers, which can make eye discomfort worse. Sleep with your head elevated on extra pillows to help reduce eyelid swelling at night.
Exercise & Movement
You can do most normal activities while you have pink eye. Avoid swimming pools and hot tubs until symptoms clear up completely. Stay home from work or school if you have viral or bacterial pink eye to prevent spreading it to others. You can usually return when discharge stops and symptoms improve.
Light exercise like walking is fine, but avoid sweaty workouts that might irritate your eyes. Don't play contact sports until pink eye is completely gone. Wear protective goggles if you do activities that could splash water or dirt in your eyes.
Prevention
Wash your hands often with soap and water, especially before touching your face
Don't share towels, pillowcases, or eye makeup with other people
Clean contact lenses properly and replace them as recommended by your eye doctor
Avoid touching or rubbing your eyes with unwashed hands
Stay away from people who have eye infections until they're no longer contagious
Keep allergy symptoms under control if you have seasonal allergies
Remove eye makeup completely before bed and replace old cosmetics regularly
Teach children to wash their hands before touching their faces. Keep shared items like phones and tablets clean by wiping them with disinfectant wipes. If someone in your home has pink eye, wash their dishes and utensils separately or in hot water. Avoid sharing pillows or bedding until symptoms are completely gone.
Check your eye makeup bottles and throw them away if they're more than three months old. Never share eye drops or ointments with other people. Remove contact lenses before going to bed and clean them properly each night.
