Seems to be conjunctivitis not sure whether it's allergic or infectious. If you have no discharge or eyelashes sticking to each other when you wake up in the morning and have only the symptoms you mentioned, then use Kitmox-LD eye drops thrice daily along with olopatadine eye drops three times daily. If you have discharge then use Moxicip eye drops 4 times a day along with lubricants and moxicip eye ointment twice daily.
Next Steps
If no improvement seen in 3 days plz consult an ophthalmologist.
