A member asked:

How much opcon-a or naphcon-a eye drops use would be bad for you?

A doctor has provided 1 answer
Dr. Stephen Hamilton answered

Specializes in Ophthalmology

Frequent use : Frequent use leads to tolerance and ineffectiveness. Everyday use will leave your eyes more injected than ever. Occasional use is ok, but for treating the underlying cause if redness or itching, there are better things your doctor can recommend.
