What's the difference between naphcon and naphcon-a eye drops?

Anti-allergic: Both drops contain a mild vasoconstrictor (naphazolamine) which can help whiten up allergically affected eyes. Naphcon-a, an alcon company brand name, also contains pheneramine, which is a mild anti-histamine. So plain naphcon can briefly eliminate the redness but does not treat anything while naphcon a can decrease the redness but also treat the allergy.

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.

Yes: Naphcon-a drops, an over the counter anti-allergic drop, can be used at the same time as you wear your contacts.
