In brief: Avoid regular use

Both drops contain naphazoline, which is a potent blood vessel constrictor. This is what "gets the red out".
If used too much it can causes rebound redness. Naphcon a contains an antihistamine as well. Try a plain allergy eye drop like zaditor, (ketotifen) alaway, or zyrtec drops.
