I would require more detail history...like if your red eye is associated with FB sensation, grittiness pain or discharge. Your kind of profession?
Now it could be just infective conjunctivitis which requires frequent antibiotic drops or allergic conjunctivitis
which would require steroid
It could be just dry eye
which would require tear substitute eye drops.
If it is not associated with anyother symtoms, you might start with Tear substitute(Optive/Refresh liquigel then visit your ophthalmologist.
