Regular readers of our blog will remember our Fun Vision Facts series and today it’s time for some more fun with optics! We’ve enjoyed putting together for you the wackiest, most surprising and wow-factor facts about all things eye-related.

Heirs and Heiresses Fun Vision Facts – Part 4

A little known fact is that everyone in your immediate family could have brown eyes and so could your aunts, grandmothers and grandfathers and yet, you could still be born with blue or green eyes!

Blue and green eyes are recessive traits and can come out generations later.

Irreplaceable

Take good care of your eyeballs because you only get one set. Though they are working hard at it, doctors and surgeons have not yet found a way to transplant eyeballs. Eyeball transplants have proven to be so elusive because the optic nerve that connects with your brain is too sensitive to successfully reconstruct as of yet!

Prevention is Key

We know we talk a lot on our blog about keeping your eyes healthy, eating the right foods and exercising them but with good reason: a whopping 80% of vision problems are actually preventable and/or curable.

20/20 Vision

Here’s a shocker: 20/20 vision is actually not the best vision you can have! 20:16 is perfect vision and 20:20 vision is excellent.

Shades of Gray

Your eyes can actually distinguish between 500 shades of gray. Think of 500 different shades of gray spread out before you and your eyes being able to distinguish between them… impressive, right?

14 Miles of Light

Feast your eyes on this: when under just the right conditions, our human eyes can see the light from a candle from a distance of 14 miles. That’s right… 14 miles! It’s pretty impressive to think that our eyes are capable of seeing something 14 miles away.

Three-Eyed Shrimp

Here’s something that may make you think twice before you dive into your shrimp cocktail; the Triops, which is a kind of shrimp, actually has three eyes.

Sunglasses: Not Just for Summer

Make sure you reach for your sunglasses in the winter as well as the summer. Snow sure is bright and it’s a little known fact that snow glare is the biggest cause of winter car accidents.

Red Eye Revealed

Ever have to retake a photo because you caught a case of red eye in it? The true cause of red eye is not a camera malfunction but is actually light bouncing off of the blood vessels in our retinas.

Interesting stuff isn’t it?

    Fourteen miles? That’s nothing!

    A few years ago on a clear moonless night I lay on my back on the lawn, armed with a star map and a small torch (to see the star map), and managed to find the constellation of Andromeda, and within that the M31 galaxy.

    It was just about visible to my naked eye, and is at a distance of two and a half million light years!

    It was just a tiny smudge, but was still one of the most thrilling things I have ever seen!

    Regards,
    John

      Amazing indeed, John. Especially when you remember that one light year is 5,878,499,810,000 miles (just shy of 6 trillion).
