As cold weather and flu season approach, we want to highlight one of the most common and easily recognizable eye conditions, conjunctivitis. Commonly known as pink eye, conjunctivitis is an inflammation of the thin, clear tissue that lines the inside of the eyelid and covers the white part of the eye (the conjunctiva). Although it is one of the most common and mild eye conditions, it can be highly contagious depending on the cause.1
Types and Causes
During the winter months, cooler weather brings people indoors and in closer contact, increasing the chance of more easily spreading viruses and bacteria that can cause pink eye. Seasonal colds and flu—common at this time of year—can accompany or trigger viral conjunctivitis. Dry indoor air and the use of heaters can also irritate the eyes and make them more susceptible to infection. Conjunctivitis can be caused by:
- Viral infections: The most common cause. This form of pink eye is often linked to colds or other respiratory infections.
- Bacterial infections: Another common source that can cause the eye to produce a watery or thick discharge.
- Allergic reactions: Triggered by allergens such as pollen, dust, or pet dander.
- Irritants: Exposure to smoke, chlorine, or contact lens solutions can cause inflammation that can lead to pink eye.2
Common Symptoms
Symptoms of pink eye include the following:
- Watery or thick discharge
- Itchy or gritty sensation
- Swelling of the eyelids
- Increased tearing
- Light sensitivity
- Crusting of eyelids and lashes3
Prevention and Treatment
Good hygiene is the best defense against infectious conjunctivitis. Wash your hands frequently, avoid touching or rubbing your eyes, and don’t share towels, makeup, or contact lenses.
Proper treatment depends on the cause:
- Viral: Usually clears on its own within one to two weeks.
- Bacterial: May require antibiotic drops prescribed by an eye care professional.
- Allergic: Managed with allergy medications or eye drops.2
