Why do flies try to get in my eyes all the time?
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?

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).
