My right eye is red. During the night, last night,
Antiinflammatory eye drops...
Based on the details, you developed acute red eye with watering overnight. I wish to know if it itches or hurts? Is your vision alright?
From the details provided, this seems like conjuctivitis. I would treat with antiinflammatory eye drops (dexamethasone eye drops) along with antibiotic drops. I don't think that's available over the counter. You need to see a doctor for a prescription.
Hope this helps. let me know if you need clarifications.
Goopy discharge is a feature of bacterial infection...
I am sorry if my previous answer wasn't elaborate. Goopy discharge is part of bacterial conjuctivitis. Redness and watering are the lone symptoms of viral or allergic conjunctivitis. Further this is not a diagnosis, but a possible cause based on the symptoms you described.
In my opinion, if the redness and watering is persistent, I believe antiinflammatory drugs along with antihistamines are necessary. Antibiotic are necessary to prevent bacterial contamination. Home remedies / OTC products may not be effective.
Hope this is clear now. Let me know if you still have questions.
