The symptoms of pink eye (conjunctivitis) typically include:

• Redness or pink discoloration in one or both eyes due to inflammation of the conjunctiva, the membrane lining the eyelid and eyeball

• Itching, irritation, or a gritty feeling as if something is in the eye

• Eye discharge that can be watery or thick; it may be clear, white, yellow, or green. This discharge can cause eyelids to stick together, especially after sleep

• Swelling of the eyelids or the conjunctiva

• Tearing or watery eyes

• Crusting around the eyelashes, especially noticeable in the morning

• Sensitivity to light (photophobia)

• Blurred vision or discomfort with contact lenses

• Burning sensation or eye pain can occur in some cases, especially if more serious conditions are involved, warranting urgent medical attention

Symptoms can vary depending on the cause of pink eye:

• Viral pink eye usually causes watery discharge and often accompanies cold or respiratory infection symptoms

• Bacterial pink eye often produces thick pus-like discharge causing eyelids to stick together

• Allergic pink eye generally affects both eyes with intense itching, swelling, and watery discharge, often alongside other allergy symptoms like sneezing or itchy nose

• Irritant-induced pink eye causes watery eyes, burning, and redness but is not contagious

Overall, pink eye symptoms range from mild irritation and redness to more pronounced discharge, swelling, and discomfort
