EPTvisine (especially the kind with astringent) can actually lead to a dependence on the drops, where your eyes just are dry and red anytime you're not using the drops. i know, it happened to me.
GenTeal has no extra ingredients in it (astringent/antihistamine/etc), and is actually a thicker lubricating fluid - to more closely mimic the actual lubricating tears in your eye. try it, youll never switch back, i guarantee it.
the only gripe i have is that the bottle makes very large drops, and with just one drop in each eye, i have to dab a little of the extra.
