Causes

Pink eye can be caused by a viral or bacterial infection, but viruses are the most prevalent. It can be accompanied by a cold or other respiratory tract infection such as sore throat due to the inflammation. Pink eye is a very contagious eye infection. It is spread via direct contact with germs, such as contact with eyedrops or tears adhering to the patient’s hands or items, by sharing things, and by inhaling or coughing. However, environmental factors can also trigger red eyes such as smoke, dust, airborne allergen, exposure to chemical, dry eye.

Symptoms¹

• Pink or red color in the white of the eye(s)
• Swelling of the conjunctiva and/or eyelids
• Increased tear production
• An urge to rub the eye(s)
• Itching and irritation
• Discharge (pus or mucus)
• Crusting of eyelids or lashes
• Contact lenses that feel uncomfortable and/or do not stay in place on the eye

Treatment
Cold compresses and artificial tears, which are available without a prescription over the market, can help relieve some of the inflammation and dryness associated with conjunctivitis. However, when it comes to pink eye, seeking medical advice is sometimes necessary.

If you feel eye pain, sensitivity to light or blurred vision, acute eye redness, or if your symptoms increase or do not improve, you should seek medical care immediately.
