what does question 1 ask again?

we don't know if antibiotic is required till we examine the eye.

 

who should one see if they believe they have this sort of infection.

and...

it's possible that antibiotics are not needed?

 

1) A physician - general practitioner - should be able to diagnose it easily.

2) Antibiotics are indicated when the conjunctivitis is a bacterial infection. When it is a viral infection or an allergic reaction antibiotics are of no use.
