These Images Can Alter Your Vision For Months

Warning: These images may affect your vision for days or even months if you look too long. The damage isn’t irreparable, though, and the worst possible side effect is that you might start seeing colors a little differently, the Indy100 notes.

It’s called the McCollough effect—named after psychologist Celeste McCollough Howard—and one of the earliest studies of this phenomenon dates back to 1975. Researchers separated 16 people into five groups and showed them two different striped patterns featuring the colors red and green.

After looking at each image for about three minutes, the test subjects then stared at black and white striped grids. That’s when the effect started to set in, and participants reported seeing a pinkish hue in the black and white images. One test group reported that the effect remained in full force after five days, while the other four groups said they still felt a weakened form of the effects three months later.

An earlier study from 1969 found that only the colors green and red produced this effect. There’s no consensus on what causes it, but some scientists believe it’s related to neurons in the visual cortex, according to IFL Science. Others have suggested that the brain tries to “color-correct” what you’re seeing, while a third theory posits that the effect is a symptom of withdrawal caused by the absence of color.

To get your vision back to normal more quickly, it’s recommended that you stare at the two images of the red and green lines, except with the image turned 90 degrees counter-clockwise.

Stranger Things Star David Harbour Officiates Fan's Wedding Thanks to Twitter Challenge

Stranger Things fans might remember back in January when Chief Hopper actor David Harbour made a kind of ​crazy agreement with an engaged fan. Seems the actor has a sweet spot just like his character!

Ericka Millholland from Springfield, Illinois tweeted at Harbour, asking how many retweets it would take for him to officiate her wedding. Surprisingly, the 43-year-old actor replied the next day, requesting 125,000 retweets, to read a love letter of his choosing, and to cut the first piece of wedding cake.

Harbour's list of demands were ultimately met, as Millholland got almost 132,000 retweets. The actor went on to get ordained, and performed the marriage ceremony this weekend. The best part? He was dressed as Hopper!

Taking to Twitter, Harbour shared a photo from the wedding with his fans, making sure everyone knew he held his promise. "And so me and some fun folks in Springfield, Illinois made good on our promise we made all those months ago," he wrote.

The wedding is hardly Harbour's first time granting a fan request on social media. Back in October, he agreed to take senior photos with a high school student from California, who reached out to him via Twitter.

Come January, Harbour was there in a full on photoshoot with Damaris Fregoso.

It's great to know such a fan-favorite actor not only acknowledges his fans, but actually hangs out and does hilarious stuff with them as well. We'll see more of Harbour when Stranger Things returns for ​Season 3 in summer 2019.

Sony Launches PlayStation Classic, Preloaded With 20 of Your Favorite Games

Nintendo proved that nostalgia is a powerful force when it released the NES Classic in 2016. Gamers have had a hard time getting their hands on the mini console since its debut, with limited releases appearing in stores with little warning and clearing out just as quickly. Now, Sony is taking a page from Nintendo's book with a retro re-release of its own. This holiday season, the media giant will release the PlayStation Classic, a smaller version of the original PlayStation that comes pre-loaded with 20 games, Polygon reports.

As is the case with the NES Classic, there's no need to pop game cartridges into the new PlayStation console. The PlayStation Classic comes with what you need to get started: two controllers, a HDMI cord for video and audio input, and a micro-USB for power. Once the system has been set up, use the power button on the console to hop from game to game and press the reset button to pause. All your data is saved to a virtual memory card.

Though there will be a total of 20 titles built in to the console, only five have been confirmed so far. Players will be able to play such classics as Final Fantasy 7, Jumping Flash, R4: Ridge Racer Type 4, Tekken 3, and Wild Arms, all playable in the format fans remember from the 1990s.

The PlayStation Classic will sell for $99 when it makes its worldwide debut on December 3—the 24th anniversary of the launch of the original PlayStation. The release date also makes it a great gift for the holidays—whether you're shopping for loved ones or yourself.
