A natural treatment for dry eyes that your doctor can prescribe is blood serum drops. Your blood is drawn, sent to a compounding pharmacy and is specific to you. The recommended dose is 4 times a day, but you can use as often as you like. The prescription is a 6 month supply, which is in a individual syringes and must be kept in the freezer. A syringe can be kept for a week in the refrigerator, using 4 times a day last about 5 days.
I have been using the treatment for 6 weeks. At my check up I had moderate improvement, at only a quarter of the way through the prescription. Our blood serum carries stem cells, so effectively we are healing ourselves.
The blood draw was $40 and the prescription was $265, even though it is spendy, at $50 a month it is certainly worth a try.
