Pink eye symptoms are among the most common eye-related complaints in both children and adults. Also known as Conjunctivitis, pink eye occurs when the conjunctiva—the thin, transparent layer covering the white part of the eye—becomes inflamed. While it is usually mild, understanding the symptoms can help you seek timely treatment and prevent spreading the infection to others.

Common Pink Eye Symptoms

One of the earliest pink eye symptoms is redness in one or both eyes. This redness happens because the tiny blood vessels in the conjunctiva become swollen and irritated. Along with redness, many people notice itching or a gritty sensation, as if sand is trapped in the eye.

Another common symptom is excessive tearing. Your eyes may water more than usual, even when you are not emotional or exposed to wind. Discharge is also typical. In viral cases, the discharge is usually clear and watery. In bacterial infections, it may be thick, yellow, or green, sometimes causing the eyelids to stick together—especially after sleep.

Swelling of the eyelids and increased sensitivity to light (photophobia) can also occur. Some individuals experience blurred vision due to excessive discharge or inflammation, but vision usually returns to normal once the condition improves.

Different Types, Different Signs

Pink eye can be caused by viruses, bacteria, allergens, or irritants like smoke and dust. Viral conjunctivitis often accompanies cold symptoms such as a sore throat or runny nose. Bacterial conjunctivitis tends to produce thicker discharge. Allergic conjunctivitis usually affects both eyes and is associated with sneezing and nasal congestion.

When to See a Doctor

Most mild cases resolve on their own within a week. However, you should consult a healthcare professional if you experience severe pain, significant vision changes, intense light sensitivity, or symptoms that worsen over time. Infants and people with weakened immune systems should receive prompt medical attention.

Preventing the Spread

Pink eye can be highly contagious, especially viral and bacterial forms. Wash your hands frequently, avoid touching your eyes, and do not share towels, makeup, or contact lenses. Replace old eye cosmetics and disinfect surfaces to reduce the risk of reinfection.
