In 2015, the Zika virus cropped up in Latin America. In doing so, it planted itself firmly in our worry-filled human minds, too.

Zika is a mosquito-borne virus that can make people very sick. It causes a variety of problems, including birth defects in unborn children.
In February 2016, the Brazilian chapter of UNICEF (the United Nations program aimed at supporting women and children in the developing world) wanted to help educate people about the disease. So they started to develop an awareness campaign.
The right message to the right people can save lives — but how do you make sure your message is right?
In most stories, this would be the place where the organization comes up with a game plan, runs it through a focus group, hires some graphic designers or copywriters, then distributes the new message. Maybe afterward, they'd do an analysis to see if they aimed right.
But in this case, that's not what UNICEF did. They suspected there might be a better way.
Before they even started on the campaign, UNICEF teamed up with Facebook to figure out who their audience for Zika actually was.
“In order to address a problem, you have to understand how the public is thinking about it," says Molly Jackman, a research manager at Facebook.
UNICEF ended up working with Facebook and another partner, ActionSprout. They pulled a bunch of anonymous, aggregated data from Brazilian Facebook, trying to find out what the public really was saying about the virus.
They ended up finding some surprising information.
One of the big secret success factors to Zika awareness? Men.

Conventional thinking was that because everyone was talking about Zika's dangers to pregnant women, any messages about health and safety should be targeted at women. Seems obvious, yeah? But it turned out men weren't exactly being silent about it.
In fact, men were responsible for the majority of posts about Zika. Moms weren't the only ones worried about Zika's potential effect on babies. Dads were too.
UNICEF realized it had accidentally ignored this huge group of people in its messaging. So it created a post specifically aimed at engaging the dads of Brazil in fighting Zika.
Based on the Facebook analysis, UNICEF was also able to hit a couple of other areas, like preemptively reinforcing that Zika wasn't a laughing matter. They also created Q&A sessions with experts and expanded their education to other mosquito-based disease.
All this work paid off. An after-the-fact analysis showed that people who got this info were not only more engaged, aware, and more likely to take action to prevent the spread of the disease, but their results beat out a traditional campaign.
Social media is a tool that can be used for good, and this story shows that.
Like all tools, we should be mindful of how we use it, of course. But the right tool in the right hands can make a huge difference.
“Trends in the public conversation are vitally important to health organizations," says Jackman. "That information can save lives.”
The internet is a big, weird place. But it's pretty cool that in this case, we harnessed it for good.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
