i have sjordens disease which involves dry eyes. i have a voporizer on in the house. i use the refresh p.m. ointment at night and during the day i use refresh eye gtts and a gel to keep my eyes moist. the doctor also thought i may have some allergy and so she gave me samples of panadol which i use twice a day. after 3 months of all this i think i now have the problem under control with this routine. hope this helps your son.
