Preservative free artificial tears might be a solution. In my opinion it is imperative that you have a very complete exam with an ophthalmologist to try to determine exactly what your problem is. Perhaps it is something other than dry eye syndrome. If indeed, you do have bad dry eyes, it is not unusual to be so senstive to drops. Sometimes there is also lid margin disease or severe allergies and treating them properly may help the overall sitaution.

Someone told me that many of the bottle drops have preservatives in them and I started to use the individual vials of eye lubricating drops because they are in sterile containers and don't need the preservatives. This seems more comfortable.
I am not a doctor, but hope this information is helpful.
