Eye flu, also known as conjunctivitis, is an inflammation of the clear tissue that lines the inner surface of the eyelid and covers the white part of the eye. It is a common eye condition that can be caused by viral or bacterial infections, allergies, or irritants. 

Symptoms of eye flu include redness of the eye, itching, watering, discharge, and sometimes blurred vision. It can be highly contagious, easily spreading from person to person through direct contact or sharing personal items such as towels or pillows. 

While most cases of eye flu are mild and resolve on their own within a week or two, it is important to seek medical advice and treatment, especially if symptoms worsen or persist. Treatment may include the use of eye drops or ointments to relieve symptoms and prevent complications. 

To prevent the spread of eye flu, it is recommended to practice good hygiene, such as washing hands frequently, avoiding touching the eyes, and avoiding sharing personal items. If you suspect you have eye flu, it is best to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
