Pink eye, also known as conjunctivitis, is a common eye infection that affects people of all ages. It is characterized by inflammation of the conjunctiva, the clear membrane that lines the eyelids and covers the white part of the eye. Pink eye can be caused by bacteria, viruses, or allergies.
The symptoms of pink eye can include redness, swelling, itching, and tearing. The white part of the eye may also appear pink or red. In some cases, people with pink eye may also experience sensitivity to light or blurred vision. Pink eye is usually not a serious condition, but it can be uncomfortable and contagious.
The length of time that pink eye lasts depends on the cause of the infection. Bacterial conjunctivitis typically lasts for 7-10 days, while viral conjunctivitis can last for up to 2 weeks. Allergic conjunctivitis can last for as long as the person is exposed to the allergen.

Allergic: As long as allergen present
Allergic pink eye is caused by an allergic reaction to an allergen, such as pollen, dust, pet dander, or smoke. When the allergen comes into contact with the eyes, it triggers an immune response that leads to inflammation and the symptoms of pink eye.
Symptoms of allergic pink eye can include redness, swelling, itching, and tearing. The eyes may also feel gritty or burning. Allergic pink eye can be mild or severe, depending on the severity of the allergy and the amount of allergen exposure.
Treatment for allergic pink eye typically involves avoiding the allergen and using over-the-counter antihistamines or allergy eye drops to relieve symptoms. In some cases, prescription medication may be necessary to control the allergy.
Allergic pink eye can last as long as the person is exposed to the allergen. If the allergen is removed or avoided, the symptoms of pink eye will usually clear up within a few days. However, if the person continues to be exposed to the allergen, the symptoms may persist.
To prevent allergic pink eye, it is important to avoid exposure to known allergens. This may mean staying indoors on high pollen days, using a dehumidifier to reduce dust mites, or keeping pets out of the bedroom. If you are allergic to pet dander, you may also want to consider bathing your pet regularly and vacuuming your home frequently.

Pink eye is a contagious infection that can be spread from person to person through contact with infected eyes or objects.
