eye flu cause

You’re describing symptoms that align with conjunctivitis, more commonly known as “pink eye,” which could indeed be viral conjunctivitis—often referred to as “eye flu.” This condition is typically caused by adenoviruses, which are highly contagious and can spread through close personal contact, like the scenario you’re describing with your friend. Touching contaminated surfaces or sharing personal items can also spread it, so it’s wise to be cautious around family and avoid sharing towels, pillowcases, or eye makeup. Viral conjunctivitis often resolves on its own within one to two weeks, but maintaining good hygiene can prevent spreading it further. Wash your hands frequently, avoid touching your eyes, and clean surfaces frequently. If the symptoms persist for more than a couple of weeks or worsen, a follow-up with your doctor might be necessary to rule out bacterial infection or other eye issues. Allergies can also cause redness and watering of the eyes, but they typically come with itching and possibly other allergy symptoms like sneezing or a runny nose. If you suspect allergies, over-the-counter antihistamine eye drops may help. Dry environments can contribute, but your symptom pattern and the timing with your friend’s similar condition suggest something communicable like viral conjunctivitis. It’s generally a self-limiting condition, but if you experience vision changes, severe eye pain, or sensitivity to light, these could be signs of something more serious, so seek medical attention promptly.
