Dietry deficiencies, particularly of Omega 3, have long been linked to the prevalence of dry eye in the western world. Omega 3s produce their beneficial effects through anti-inflammatory properties. We recommend supplementation with one of the commercial dry eye preparations as the first course of action before considering prescription medication to control inflammation. The course should last no less than 3 months to gain the full benefit. The commercial preparations are preferred initially as they offer the optimum concentration of vitamins with the perfect balance of Omega 3 and Omega 6. Once under control more economical alternatives can be considered for the longterm. It would be advisible to also alter your diet to include some oily fish such as those listed below. Like most dry eye treatments it is important to continue supplementation indefinitely.
