I use eye drops all the time but I thought I heard somewhere, that some eyedrops will irritate your eyes after using them too much. I use ClearEyes and it doesn't work as good as it once used to but I still use it it because it's better than not using it. I'd like to try something new but I'm too paranoid that it may screw up my eyes. Has anyone used this Rhoto-v or Rohot-v for a long time?
