Will Sitting Too Close To The TV Hurt Your Eyes?

When you were little, your mom probably told you not to sit too close to the television, lest you irreparably harm your vision. But you can file this popular warning in the myth file, right next to "your face will get stuck that way"—in reality, sitting close to the TV won't hurt your eyes. So why do parents the world over still say this to their kids? Because there was actually a very brief period of time where sitting close to the TV could damage your eyes—at least, if you owned a General Electric TV in the late 1960s.

In 1967, General Electric informed the public that many of their color televisions were emitting excessive x-rays due to a “factory error." Health officials at the time estimated that the amount of radiation coming from these defective TVs was about 10 to 100,000 times higher than the rate considered acceptable. They recommended keeping children a safe distance away—but as long as you were a few feet away and didn’t watch TV for more than an hour at a time or so at close range, you were probably fine. General Electric recalled all of the defective TVs and fixed the problem by putting a leaded glass shield around the tubes, making up close and personal television viewing safe once again.

"It's not an old wives' tale; it's an old technology tale," Dr. Norman Saffra, the chairman of ophthalmology at Maimonides Medical Center in Brooklyn, told the New York Times. "Based on the world our grandmothers lived and grew up in, it was an appropriate recommendation."

At worst, sitting excessively close to the television these days will give you a headache and possible eyestrain. This can sometimes be a problem for kids, who often watch TV while lying on the floor; looking up at the television this way causes more eyestrain than looking straight at the TV or down at it. (The same applies for computer monitors.) Eyestrain can also occur when watching TV or looking at a computer screen where the light level of the screen is very different than the light level of the surrounding environment. Thankfully, eyestrain isn't permanently damaging, and is very easy to fix—just take a break from watching TV.

Big Questions
How Are Royal Babies Named?

After much anticipation, England's royal family has finally received a tiny new addition. The birth of the Duke and Duchess of Cambridge's second son was confirmed by Kensington Palace on April 23, but the name of the royal newborn has yet to be announced. For the heir to the British throne and his wife, choosing a name for their third child—who is already fifth in line to the throne—likely won't be as easy as flipping through a baby name book; it's tradition for royals to select names that honor important figures from British history.

According to ABC WJLA, selecting three or four names is typical when naming a royal baby. Will and Kate followed this unwritten rule when naming their first child, George Alexander Louis, and their second, Charlotte Elizabeth Diana. Each name is an opportunity to pay homage to a different British royal who came before them. Some royal monikers have less savory connotations (Prince Harry's given name, Henry, is reminiscent of a certain wife-beheading monarch), but typically royal babies are named for people who held a significant and honorable spot in the family tree.

Because there's a limited pool of honorable monarchs from which to choose, placing bets on the royal baby name as the due date approaches has become a popular British pastime. One name that keeps cropping up this time around is James; the original King James ruled in the early 17th century, and it has been 330 years since a monarch named James wore the crown.

If the royal family does go with James for the first name of their youngest son, that still leaves at least a couple of slots to be filled. So far, the couple has stuck with three names each for their children, but there doesn't seem to be a limit; Edward VIII, who abdicated the throne to George VI in 1936, shouldered the full name of Edward Albert Christian George Andrew Patrick David.

Big Questions
Why Does the Queen Have Two Birthdays?

On April 21, Her Majesty Queen Elizabeth II will turn 92 years old. To mark the occasion, there are usually a series of gun salutes around London: a 41 gun salute in Hyde Park, a 21 gun salute in Windsor Great Park, and a 62 gun salute at the Tower of London. For the most part, the monarch celebrates her big day privately. But on June 9, 2018, Her Majesty will parade through London as part of an opulent birthday celebration known as Trooping the Colour.

Queen Elizabeth, like many British monarchs before her, has two birthdays: the actual anniversary of the day she was born, and a separate day that is labeled her "official" birthday (usually the second Saturday in June). Why? Because April 21 is usually too cold for a proper parade.

The tradition started in 1748, with King George II, who had the misfortune of being born in chilly November. Rather than have his subjects risk catching colds, he combined his birthday celebration with the Trooping the Colour.

The parade itself had been part of British culture for almost a century by that time. At first it was strictly a military event, at which regiments displayed their flags—or "colours"—so that soldiers could familiarize themselves. But George was known as a formidable general after having led troops at the Battle of Dettingen in 1743, so the military celebration seemed a fitting occasion onto which to graft his warm-weather birthday. Edward VII, who also had a November birthday, was the first to standardize the June Trooping the Colour and launched a tradition of a monarchical review of the troops that drew crowds of onlookers.

Even now, the date of the "official" birthday varies year to year. For the first seven years of her reign, Elizabeth II held her official birthday on a Thursday but has since switched over to Saturdays. And while the date is tied to the Trooping the Colour in the UK, Commonwealth nations around the world have their own criteria, which generally involve recognizing it as a public holiday.

Australia started recognizing an official birthday back in 1788, and all the provinces (save one) observe the Queen's Birthday on the second Monday in June, with Western Australia holding its celebrations on the last Monday of September or the first Monday of October.

In Canada, the official birthday has been set to align with the actual birth date of Queen Victoria—May 24, 1819—since 1845, and as such they celebrate so-called Victoria Day on May 24 or the Monday before.

In New Zealand, it's the first Monday in June, and in the Falkland Islands the actual day of the Queen's birth is celebrated publicly.

All in all, just another reason it's great to be Queen.
