We spend a lot of time staring at screens. There’s the small screen in our pocket, the big screen we watch our shows on, and the medium screen that many of us stare into for eight hours a day to help pay for those other screens. Are all of these screens ruining our eyes?

Probably not, although rumors abound. If you grew up with big ol’ tube TVs, you probably remember being told that sitting too close would ruin your eyes. Scientific American traces that myth to a 1967 recall of early color TVs that emitted radiation (like, actual radiation) that were probably harmful to health, as well as to a misunderstanding about nearsighted kids who sat close to the TV. Most likely, they sat close so they could see better; the TV didn’t cause their nearsightedness.

When it comes to the variously sized screens we stare at all day, there are some new myths (and facts!) about how they affect our vision.

Like motorcyclists, U.S. Navy pilots “dress for the slide, not the ride.” Their gear is meant for frost, flames, and flotation. Even the very first pilot to operate from a ship carried safety equipment: Eugene Ely, attempting his landing on the deck of the armored cruiser USS Pennsylvania in 1911, took the controls of his Curtiss Pusher wearing a leather football helmet, bug-eyed motoring goggles, and a makeshift life vest fashioned from bicycle inner tubes.

The odds of a mission ending with an ejection from the cockpit are slim—it happens precisely 1.33 times per 100,000 hours of flying, according to the Navy. But naval flight officers still carry equipment for just such a scenario. “Most of the gear is only for emergency use,” says Lt. Luke “Oslo” DeLisio, a flight officer from Strike Fighter Squadron (VFA) 106. “But when you need it, you’re glad it’s there.”

As a self-proclaimed night owl, I’m rarely surprised when I lift my eyes from Instagram and see that it’s well past when I intended to go to sleep. Here’s how I explain it to myself: I’ve always stayed up late, and now the only time I get to myself is when my husband and daughter are asleep. Here’s what’s actually going on: I’m procrastinating.

Some researchers call this bedtime procrastination or while-in-bed procrastination, while the Chinese word for it translates to “revenge bedtime procrastination.” No matter what you call it, in my case, it involves a combination of technology and anxiety; I worry that I won’t be able to fall asleep quickly, so I tell myself that I’ll just scroll through social media until I’m exhausted. It is this—along with a lack of what researchers refer to as self-regulation—that makes me a textbook sleep procrastinator.

How Sleep Procrastination Happens

The idea of sleep procrastination was first introduced in a 2014 study from the Netherlands, defining the act simply as “failing to go to bed at the intended time, while no external circumstances prevent a person from doing so.” Revenge was added to the title in 2020 with the onset of the pandemic, but as a concept, it has actually been around for much longer.
