I read your story and wanted to share my health experience with you. I too suffer from “Dry Eye” and use Ivizia eye drops, which are over the counter. They are preservative free. I also suffer from Hashimoto’s and Hypothyroidism which is an autoimmune disease. I take 56 mcg of Synthroid to regulate the Hypothyroidism. Most recently, I went from taking 100 mcg to this lower 56 mcg dose. I have noticed that my eyes are more blurry and feel dry. Even though I’ve been using the above mentioned drops. It could be that it’s winter and more dry in our home or the bitter cold weather we’ve been having (live in Chicago area), but I have noticed this too. Do you take any supplements? You may be lacking in a particular vitamin, I don’t know, but listen to your body and find a doctor who will help you, not just put a band aide on it! Good luck!
