Understanding Conjunctivitis (Pink Eye)
Conjunctivitis, or pink eye, is a common eye problem that affects people of all ages. It causes red eyes, which can be scary and uncomfortable3. There are different types of conjunctivitis, each with its own signs and ways of spreading.
We’ll look at the different types of conjunctivitis to help you understand this common eye issue:
- Viral Conjunctivitis: This is the most common type of pink eye. It spreads fast in places like schools and daycare centers3. It often comes with colds and can move from one eye to another quickly3.
- Bacterial Conjunctivitis: You can get it from touching contaminated surfaces or from direct contact with someone4. It usually starts in one eye and might spread to the other3.
- Allergic Conjunctivitis: It’s caused by things like pollen or animal dander. It makes your eyes red, watery, and itchy4.
Characteristics of Conjunctivitis Types
Knowing the differences between these types is key for the right treatment and prevention. Each type has its own symptoms and risks of spreading:
Type | Discharge | Contagious | Typical Duration |
---|---|---|---|
Viral Conjunctivitis | Clear, watery | Highly contagious | 7-14 days |
Bacterial Conjunctivitis | Thick, yellow/green | Contagious | 2-5 days |
Allergic Conjunctivitis | Watery | Not contagious | Varies with allergen exposure |
Anyone can get conjunctivitis, but kids are more likely to get it because of close contact in school3. Keeping clean and seeing a doctor quickly can help manage and stop the spread of this common eye problem4.
Causes of Conjunctivitis
Conjunctivitis is a complex eye condition with many causes. These causes can lead to eye irritation and discharge. Knowing the causes helps patients manage their symptoms better5.
Viral Causes of Conjunctivitis
Viral conjunctivitis is the most common form. Adenoviruses cause 65% to 90% of cases5. This type usually gets better in 2 to 3 weeks and can spread quickly6.
- Primary viral sources include adenoviruses
- Typically affects one eye initially
- Highly contagious transmission
Bacterial Causes of Conjunctivitis
Bacterial conjunctivitis is more common in children. Various bacteria can cause this condition:
- Staphylococcus aureus
- Streptococcus pneumoniae
- Neisseria gonorrhoeae (most common in specific populations)5
Allergic Causes of Conjunctivitis
Allergic conjunctivitis comes from environmental triggers. Seasonal changes affect allergies, with summer and spring being riskier5. Common allergens include:
- Pollen
- Dust mites
- Pet dander

Symptoms of Conjunctivitis
It’s important to know the signs of conjunctivitis to get treatment quickly and stop it from spreading. Eye redness and irritation are key signs that something is wrong with your eyes. Pink eye symptoms can change based on the cause.
Common Symptoms
Conjunctivitis often shows several clear signs:
- Redness in one or both eyes7
- Burning or gritty sensation7
- Itching and discomfort
- Increased tear production
- Discharge that may cause eyelids to stick together
Severe Symptoms
Some cases of conjunctivitis can have serious symptoms that need quick medical help:
- Intense pain in the eyes
- Significant vision changes8
- Extreme sensitivity to light
- Persistent symptoms lasting more than a week7
Differences in Symptoms by Type
The symptoms can differ based on the type of conjunctivitis:
Type | Key Symptoms | Contagiousness |
---|---|---|
Viral | Watery discharge, develops in 5-12 days8 | Highly contagious for up to 2 weeks8 |
Bacterial | Thick, sticky pus discharge7 | Contagious until antibiotics start8 |
Allergic | Intense itching, no discharge | Not contagious7 |
Prompt recognition of symptoms can help prevent complications and ensure appropriate treatment. If you have ongoing eye irritation or unusual symptoms, see a healthcare professional.
Duration of Conjunctivitis
Knowing how long an eye infection like Conjunctivitis (Pink Eye) lasts is key. It helps manage expectations and find the right treatment. The time it takes can vary a lot, depending on the type of conjunctivitis.
Most eye infections are caused by viruses and affect both kids and adults9. The disease’s course depends on its cause:
Acute vs. Chronic Conjunctivitis
- Viral conjunctivitis usually lasts two to three weeks9
- Symptoms can get worse in the first three to five days before getting better9
- Morning crusting can last up to two weeks9
Bacterial conjunctivitis has a different timeline. In kids, bacterial infections are more common9. With the right antibiotics, symptoms can clear up fast. Most bacterial infections get better with eye drops or ointment9.
Progression and Spread
Viral conjunctivitis can spread quickly. The second eye often gets infected within 24 to 48 hours after the first eye shows signs9. Keeping clean can help stop it from spreading.
Patients should know that lasting symptoms beyond two weeks need a doctor’s check-up9.
There’s a risk of complications, like cornea inflammation that could harm vision. Quick and right treatment can lower these risks10.
Primary Treatments for Conjunctivitis

Each type of conjunctivitis needs a different treatment. The choice depends on whether it’s viral, bacterial, or allergic11.

- Polymyxin B with trimethoprim is good for mild cases12
- New antibiotics like besifloxacin target the infection12
- Severe cases might need intravenous treatment12
Over-the-Counter Options
There are many non-prescription treatments for eye inflammation:
- Artificial tears (2-4 times daily)13
- Antihistamine eye drops for allergies13
- Nonsteroidal anti-inflammatory drugs to lessen redness13
For allergic conjunctivitis, you can use oral antihistamines once a day or eye drops twice a day13. Always talk to a healthcare professional for advice tailored to you131112.
