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

In brief: 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.
