Never heard of them. But all parasitic insects are drawn to my eyes. They all seem to try to fly inside them. Black flies, normal ones, are the worst obviously, and if one wants in your eye, it will keep at it again and again for minutes until it makes it.
Some go for the lungs obviously, as far as "deet" suggestions go, peppermint oil is better, mix with water in a spray bottle, spray yourself. Catnip oil works better than deet like peppermint does, which is all fine and well until you run into a mountain lion.
