Normally we write about serious topics about your vision. However, today I’m doing something different. Through our research we always run across fun vision facts, or interesting sayings that we’ve all heard our entire lives, but never realize where they originate from. Today I’m going to tell you where the common phrases “you’re blind as a bat” and “eagle eye” come from, plus a tip on speed reading on your computer. Enjoy!
Computer Screen Reading
People generally read 25 percent slower on a computer screen compared to paper.
Tip: In order to read faster you can use your cursor. When starting to read on your computer use your cursor to track exactly where you are. Whenever I do this, I always follow right behind of where I’m reading so the cursor never gets in my way. Following this tip makes it easier too keep track while reading. In addition, it helps you to keep a steady pace while reading. In fact, try it as you read this article now.
It Happened in the Blink of an Eye
Ever notice how many times your eyes blink? Probably not, because we blink so fast. One blink takes around 1/10th of a second. The average person blinks about 12 times a minute. That’s an amazing 10,080 blinks in a day (14 waking hours). That’s why when someone says “it happened in the blink of an eye,” it really means it happened fast!
Someone Loses an Eye
The phrase, “It’s all fun and games until someone loses an eye” dates from Ancient Roman wrestling matches where the only rule was, ‘no eye gouging.’ Biting, kicking and scratching were allowed, but the only way to be disqualified was to poke out someone’s eye. [Source: Useless Facts]
The Human Eye
- The human eye can distinguish 500 shades of the gray.
- The human eye weighs approximately 28 grams.
- All babies are color blind when they are born.
- The cornea is the only living tissue in the human body that does not contain any blood vessels.
Did you know the average person can see an object such as a rabbit from 550 yards away? It will look more like a spec, but you can still make it out. An eagle on the other hand can see the same rabbit from one mile away, or 1760 yards. So the next time you hear someone say “you have eyes like an eagle,” you know the true meaning!
Blind as a Bat
Have you ever been told you are blind as a bat? It’s a common misconception that bats are blind. In reality almost all bats can see. Their sense of sight and smell is well developed, but they don’t use eyes to “see” where they’re going. They use sound waves. They make high pitched sounds and then listen for the echoes caused when the sounds bounce off an object. Some bats can fly at a speed of up to 30 miles per hour. Their “radar” must be pretty good to fly that fast at night! [Source: optima-hyper.com]
