What Is Pink Eye (Conjunctivitis)?
Pink eye, also called conjunctivitis, is caused by allergies or an infection that results in the inflammation of the conjunctiva (clear tissue covering the white of the eye).
There are three types of pink eye:
- Bacterial conjunctivitis. It is usually caused by bacteria that also cause strep throat.
- Viral conjunctivitis. It is typically caused by the common cold virus.
- Allergic conjunctivitis. It is caused by environmental allergies.
Since there are different products in the market, this article highlights the best eye drops for all three types of pink eye and when to see a doctor for worsening symptoms.
4 Best Eye Drops for Pink Eye
The kind of eye drops that work best will depend on the type of pink eye you have. For example, antibiotic eye drops will only effectively treat bacterial conjunctivitis. On the other hand, allergic conjunctivitis symptoms can be relieved with artificial tears and antihistamine drops.

When Should You See a Doctor for Pink Eye?
Many cases of pink eye will heal themselves in one to two weeks and don’t require treatment. However, you should seek medical attention if you:
- Have eye pain
- Experience changes to your vision
- Are highly sensitive to light
- Symptoms have not subsided after a week or more
- Worsening symptoms
- Have a lot of pus or mucus in your eye
- Develop a fever
- Are around an infant with symptoms of an eye infection
Are Eye Drops for Pink Eye Safe to Use?
Topical antibiotics are safe and effective at minimizing symptoms and killing bacteria that cause bacterial conjunctivitis. However, studies are finding that many cases of pink eye don’t need a prescription and should be allowed to heal independently.
One study found that eye doctors prescribe antibiotic eye drops to 60% of patients with pink eye symptoms, even though many don’t have bacterial conjunctivitis. Unnecessary antibiotics can end up prolonging symptoms.6
Homeopathic artificial tears, lubricating eye drops, and other OTC eye drops do not require approval by the Federal Drug Administration (FDA), leaving the safety and efficacy of many eye drops untested.
How Do You Get Diagnosed With Pink Eye?
Pink eye can be tricky to diagnose because many eye conditions have the same symptoms. It can also be hard for an eye doctor to distinguish between different types of pink eye, resulting in the wrong treatment.
Viral pink eye is the most common eye infection and is highly contagious. Artificial tears can ease symptoms but cannot cure it. Similar to the common cold, it will subside on its own.
Bacterial pink eye is also very contagious. It is the only type treated with antibiotic drops.
Allergic conjunctivitis isn’t contagious and typically disappears independently after removing environmental triggers. Over-the-counter (OTC) antihistamine eye drops and artificial tears can help reduce symptoms.
Causes
Several factors can lead to conjunctivitis symptoms. Besides viral infection, the most common causes are bacterial infection and allergies. (dust, pollen, grass, animal dander, etc.)
Symptoms
Symptoms of pink eye include:
- Red eyes
- Burning and itchiness
- Watery eyes
- Blurred vision
- Sticky pus-like discharge
- Swollen eyelids
Other Treatments
Conjunctivitis does not always need to be treated with eye drops. Several home remedies can help relieve symptoms, including:
- Applying a warm or cold compress to the affected eye(s)
- Eliminate environmental triggers that cause allergies
- Wash your hands and face
- Avoid touching your eyes
- Stop wearing contact lenses
- Don’t wear eye makeup
- Take ibuprofen or other OTC pain killers
Preventing the Spread of Pink Eye
Since both viral and bacterial conjunctivitis are highly contagious, preventing it from spreading to your friends, family, coworkers, and classmates is important.
Tips on preventing the spread of pink eye include:
- Wash your hands often
- Avoid touching your eyes
- Don’t share items with others while you have an eye infection
- Change your pillowcases and sheets daily
- Stay home from work and school until symptoms have subsided
- Don’t wear contact lenses or eye makeup
Summary
Pink eye (conjunctivitis) is a contagious eye condition caused by bacteria, viruses, or environmental allergies. Treatment usually requires specific eye drops depending on the underlying cause.
Antibacterial eye drops can only treat bacterial pink eye, while artificial tears, lubricating drops, and antihistamine eye drops can help relieve allergic and viral conjunctivitis symptoms.
Even without treatment, most cases of pink eye will resolve themselves in one or two weeks. Remember to consult your doctor if your symptoms remain or worsen beyond this period.
