You have dryness in eyes, hashimoto's, hypothyroid, face swollen you are sensitive to gluten
I think u r suffering from some auto immune disease, in which the body itself creates self antigens for its own organs, which create malfunctioning of that organ. for example your thyroid gland, causing hypothyroidism
This auto immune disease has also affected your lachrymal (tear producing gland of eyes), causing reduced production of tear.Less tear production keep your eyes dry as the layers of tears are gone from eyeball, when ever you blink your eyes, it causes micro-injury
to your cornea
, which is causing it damage and the haziness.
The main treatment is to use artificial tear drops available in medical store, regularly and maybe lifetime !!
hope my info helped you
get well soon
