Instead of punching, they are grabbing at their eyes, the back of their necks, hitting at their ears and even rubbing their noses. It is definitely not an accident, when those tiny gnats begin to swarm into people’s faces and end up in their eyes.
Gnats are non-biting pests, no bigger than a few grains of salt, are attracted to fluids secreted by your eyes—in fact, they are also known as “eye gnats” or “eye flies.” There are hundreds of different gnat species worldwide
The Smithsonian scientist will pointed out, when viewed under a microscope; they are “true” flies, because they have two wings instead of four wings. Male gnats will amass in large mating swarms rarely seen, particularly during dusk right before the darkness is complete.
Interestingly, “there are scant records of chloropidae from ancient amber deposits, mostly from the Eocene and Oligocene periods; although, some material may suggest the family dates back to the Cretaceous or earlier,” according to information about the origin of gnats is posted on Wikipedia.
One of the more common ones in the U.S., especially in the southeastern states where there is loose sandy soil for the gnats to lay their eggs in. In addition, while a gnat’s life cycle can be as short as 11 days that does not guarantee relief from these persistent pests— they can have multiple generations in one season.

Thaumatomyia notata, the 'Yellow Swarming Fly', is a well-known species of 'frit flies' or 'grass flies' belonging to the family Chloropidae, to actually learn more about gnats visit the Smithsonian National Museum of Natural History.
As they have done since pre-historic times they not only invade neighborhoods, buildings and parks they will continue to belong long after humankind is gone, because they were around before there is a record of humankind.
