I have flies always trying to get in my eyes and I wear glasses. The flies just fly right into my eye and it stings from where my eyes are dry. Why are they attracted to my eyes?

    We already have a similar question on TGO: outdoors.stackexchange.com/questions/4156/… "You are likely talking about eye flies. They feed on lachrymal secretion which your eyes produce." – ppl Jul 7 '14 at 19:27
  • To me they are different questions; Why do they fly in my eyes? How to deal with them? I referenced to other question because one of the answer explains the why. – ppl Jul 10 '14 at 20:21

Short answer moisture and salts.

This is a particular problem if you're in a jungle area, they're isn't much salt in jungles and flies will obtain it form anywhere they can. Humans secrete salts (in sweat).

Eye flies feed on lachrymal secretion which your eyes produce.


they feed on lachrymal secretions and other body fluids of various animals, including humans and are of medical significance.


The lacrimal glands are paired almond-shaped glands, one for each eye, that secrete the aqueous layer of the tear film. [...] The lacrimal gland produces tears which then flow into canals
