Pink Eye
See:

Pinkeye is a highly infectious bacterial disease affecting the eyes of cattle.
The name identifies the redness and swelling of the lining of the eyelid and eyeball.
Latest tests confirm that pinkeye can be cured by treatment with oxytetracycline, penicillin and sulfonamides.
As you are most likely dealing with a bacterial infection, the more appropriate medication is penicillin.
In addition you may want to use a 50/50 water/hydrogen peroxide eye/face wash .
I use a squirt bottle and shoot it right in the eye and on the face.
The three main elements to preventing pink-eye are:
1. Vaccination
2. Pasture mowing and pasture rotation
3. Fly control
An ounce of prevention is worth a pound of cure!
