Understanding Conjunctivitis: Symptoms You Shouldn’t Ignore

You wake up with red, itchy eyes and some crusty buildup on your lashes. Your first thought? “Did I sleep with my contacts in?” Maybe. But it could also be something more common—and more contagious: conjunctivitis, also known as pink eye.

Whether you’re a parent, a student, or someone who spends all day staring at screens, conjunctivitis is something you’ll likely encounter at some point. Knowing the symptoms and how to manage them can make a big difference in comfort, treatment, and preventing the spread.

What is Conjunctivitis?

Conjunctivitis is the inflammation of the conjunctiva—the thin, clear tissue that lines the inside of your eyelid and covers the white part of your eye. When it becomes irritated or infected, the blood vessels in the conjunctiva become more visible, giving the eye a red or pink appearance.

There are several types, each with its own cause and treatment. But first, let’s break down the common symptoms to watch out for.

Common Symptoms of Conjunctivitis

While symptoms can vary slightly depending on the cause (viral, bacterial, or allergic), here are the most typical signs that you might be dealing with conjunctivitis:

1. Red or Pink Eyes

The hallmark sign. One or both eyes may appear bloodshot or pink due to inflammation.

2. Watery or Mucous Discharge

• Viral pink eye tends to produce a clear, watery discharge.

• Bacterial pink eye often causes thicker, yellow or green discharge.

• Allergic conjunctivitis may result in watery discharge with accompanying itchiness.

3. Crusty Eyelids and Lashes

You might notice crust forming on your eyelashes, especially when you wake up. In some cases, the eyelids may even stick together.

4. Itchy or Gritty Sensation

Many people describe it as feeling like sand in the eye. This symptom is particularly common in allergic conjunctivitis.

5. Swelling of the Eyelids

The inflammation can cause the eyelids to swell slightly, sometimes making it difficult to fully open the eye.

6. Sensitivity to Light

In more serious cases, you might experience photophobia (light sensitivity). If this happens, it’s a good idea to seek medical attention quickly.

What Causes Conjunctivitis?

Understanding the cause can help you manage the symptoms and avoid infecting others:

Viral Conjunctivitis

The most common type—often associated with the common cold. It’s highly contagious and usually spreads through coughing, sneezing, or touching contaminated surfaces.

• Bacterial Conjunctivitis

  This can result from bacteria like Staphylococcus or Streptococcus. It's also contagious and may require antibiotic eye drops.

  
  

• Allergic Conjunctivitis

  Triggered by allergens such as pollen, dust mites, pet dander, or contact lenses. Not contagious, but very uncomfortable.

How to Prevent the Spread

If you or someone in your home has pink eye, here are some key precautions:

• Wash hands frequently and thoroughly

• Avoid touching or rubbing your eyes

• Don’t share towels, pillows, or cosmetics

• Disinfect commonly touched surfaces

• Keep kids with contagious conjunctivitis home from school or daycare

  
  

When to See a Doctor

While many mild cases of conjunctivitis clear up on their own, you should see a healthcare provider if:

• You experience eye pain or blurred vision

• Symptoms worsen or don’t improve after a few days

• There’s intense redness or swelling

• You suspect it’s bacterial or need treatment for allergic conjunctivitis

For contact lens wearers, remove your lenses at the first sign of redness and consult your eye doctor. Never wear lenses during an active infection.

Conjunctivitis is common, uncomfortable, and in many cases, easily treatable. The key is knowing what to look for—and acting quickly to treat symptoms and stop the spread. So the next time you feel like there’s “something in your eye,” don’t just blink it away. Check for the signs, care for your eyes, and when in doubt, get checked out. Your eyes will thank you.
