If you need to use non-prescription eye drops on a regular basis, for dry eye, never EVER use visine or any of that bottled garbage. Anyone using artificial tears on a regular basis needs to use PRESERVATIVE FREE -single use vials- of eye drops, like refresh (in vials, not bottles), theratears, bion tears, ect.
While these are safe to use on an extremely frequent basis, using them regularly may mean that your dry eye needs to be treated via some alternate means as well, such as plugs, compresses, flax oil, moisture chambers, ect.
Never use 'get the red out' drops on a more than EXTREMELY infrequent basis.
