Wear goggles, ladies and gents. You're gonna need 'em.

In a shocking, disturbing, and precedent setting case, a total of 14 surface-dwelling (and sexually breeding) "cattle worms," referred to taxonomically as Thelazia gulosa, were found content to feed on tears rather than burrowing into the brain as feared by an Oregon woman, after she'd made contact with a face fly, the parasite's other host.

Initially suspecting a stray hair strand, she couldn't believe her eyes, however, as she was forced to stare in the mirror and peripherally inspect the left eyeball after days of lingering and severe irritation, discovering what appeared to be translucent fuzz wiggling around on her eyeball, proceeding to extract the fuzz with her bare hands and realizing it was a live worm fighting to stay alive...

CDC basically had to be called in, and like all important news stories of our time, it was first broken by the very fine people of Buzzfeed:

Luckily for her, she started plucking them just in time, for had they been left to their own devices, the mild case of pink eye would've resulted in burrowing beneath the surface to scratch the cornea and effect blindness.

After two unsuccessful visits to clinics ... Beckley flew home and visited specialists at the Oregon Science and Health University in Portland. The team extracted two worms and sent a preserved sample to the CDC. Over the next few weeks, each time she felt a twinge, Beckley would reach in and pull out another worm or two, to make a total of 14.
