I remember having blepharitis myself, about 14 years ago, and my doctor told me it was because I was allergic to some kind of chemical in the workplace (I had just changed job functions at my job, working in the cargo area of an airline). But the condition eventually went away with the application of the ointment and warm eye scrubs like you had mentioned. My Dad has had this condition for a long time. Will it eventually go away? Why hasn't his doctor told him it was blepharitis?
