A member asked:
Is too much opcon-a or naphcon-a eye drop use bad for you? how much is too much?
A doctor has provided 1 answer
Yes: Both these drops are vaso-constrictors that constrict the blood vessels on the surface of the eye. They should only be used for a short time. Long term usage can cause rebound vaso-congestion which results in worsening redness in the eyes when the drop is not used. Using it more than a few times a day for a few weeks is likely too long.
