Do you know when the last time the United States fired a nuclear weapon?
The bombs that destroyed the Japanese cities of Hiroshima and Nagasaki are the only nuclear weapons to have ever been used against a population, but they're not the only ones America's set off. Throughout the 20th century, the United States conducted well over 1,000 nuclear weapons tests.
America set off the Trinity test — their first nuclear weapon — on July 16, 1945. But here's an interesting question: When was the most recent time they set one off?
It must be a while ago, right? The concept of American nuclear weapons testing seems like a relic of the 1950s, back when we nuked entire atolls and fearless (or maybe clueless) tourists would travel down from Las Vegas to watch the detonations.
But guess what? The last American nuke went off in the '90s. Yep, the 1990s.
You know, the era that not only saw the final dismantling of the Berlin Wall and an economic boom, but also gave us Goosebumps books, Tweety Bird T-shirts, the Nintendo 64, and introduced the world to the cultural dreadnought known as Pokémon.

The reason we didn't have any more mushroom clouds over the Vegas strip wasn't because they stopped — it's because they started setting the bombs off underground instead. The 1,030th — and last — American nuclear test took place under the Nevada desert on Sept. 23, 1992.

That November, Bill Clinton would beat Ross Perot and George H.W. Bush to become the 42nd president of the United States. If you're 43 now, that means you probably turned 18 around that time. Who did you vote for?

PG-13 never looked so weird. This year also saw the release of Disney's "Aladdin," "The Muppet Christmas Carol," and "Reservoir Dogs."

Though nuclear testing might seem like something from the historical archive, it's important to remember the use of nuclear weapons is not that far behind us.
In 1996, President Clinton signed the Comprehensive Test Ban Treaty, which prohibited any country from testing nuclear weapons. Many countries, including the U.S., have also pushed for nuclear disarmament altogether, arguing that the only way to ensure nobody uses nuclear weapons is for nobody to have them in the first place.
Still, we have a ways to go. It's estimated that about 15,000 nuclear weapons are still around, 6,800 of which are in the United States. While Trump has said he supports abolishing nuclear weapons, he's also talked about using nuclear weapons against ISIS and arming countries such as Japan, South Korea, and Saudi Arabia.
Though it's been years since America has used a nuclear weapon, it's only through continued effort that disarmament can happen.

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.
