Fun Vision Facts – Part 1

Fun Vision FactsNormally 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 A 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 colour blind when they are born.
  • The cornea is the only living tissue in the human body that does not contain any blood vessels.

Eagle Eye

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:]

So how did it work out using your cursor to read faster?


About Orlin Sorensen

My vision started to get blurry as a young teenager. Soon I was wearing glasses for just about everything. This was a hard blow for me because I had always dreamed of becoming a U.S. Navy fighter pilot which required perfect vision without glasses or surgery. But I wasn't ready to give up on my dreams, so I looked into every possible alternative which led me to eye exercises. Through daily vision training and eye exercises, I improved my vision from 20/85 to 20/20 and passed the Navy's visual acuity test. In fact Men's Health declared this one of the "Greatest Comebacks of All Time!" Now, I'm sharing exactly how I did it with the program that helped me so people like you can improve your vision safely and naturally, without glasses, contacts or laser surgery.

    very good

    I found that I read faster without the cursor. I have a mouse pad instead of an actual mouse, and I couldn’t move the cursor as fast as I can read.

  3. Lepakiyo #

    Very good.You mean the eyes of an eagle are like a pair of binoculars?

  4. Jane #

    Thank you, you always good in helping people with your nice and important topics.

    thanks for the computer speed reading tip. It really helps out a lot for my eyes to exercise them. Eagle eye vision is comparable with that of the peregrine falcon’s vision.

    Reading all the stories about seeing I have never heard you talk about Salzman’s Nodules. I have had them and was almost “blind as a bat” with 2200 vision in my left eye and starting to get the nodules on the right eye. I think it would be a good thing if you could talk about that.

    thanks for the tip, if found it effective to guide reading with the cursor. but I found it difficult to learn the three cups technique.

  13. Simeon Z. Woheel #

    Thank you again for Fun Vision Facts and thanks for the advice to use the cursor to guide my reading on the computer .I didn’t know that the eagle eye sees far more than three times the human eye. Thank you for the tips.

    No, I am not as blind as a bat, but I often wonder how a bat will navigate its way around in the absence of an object for its sonar to bounce back to produce an echo?

    I have followed your blog and been doing exercises sporatically and have seen some improvement in my near vision. I am still having some trouble with my distant vision and have recently been diagnosed with a cataract. Any suggestions? Any doctors in the Atlanta area that follow your methods?

  15. Hi Ginger,

    Congratulations on the improvement on your near vision.

    Dear Sorenson,
    Thanks for the article. It really works by using the cursor. Can read faster.
    I had cataract surgery on one eye about 3 months ago, May I know whether I can do eyes exercises?

    thank you
