When we look at some of the most remarkable things on earth, we often think of the incredible technological solutions that surround us, or the advanced cars that we drive and so much more.

The truth is though, if you really want to witness something incredible, all you have to do is look in the mirror. While you are probably thinking we are going to get into some deep conversation about loving yourself, that isn’t where this post is going at all.

In fact, this post is going to be acknowledging just how amazing the human body is, or more specifically, the human eye. It seems that on a daily basis, each and every one of us takes advantage of the remarkable feats that our bodies are capable of.

Today, we are going to be looking at some incredible facts about the human eyes that you may or may not know. Hopefully, by the time you reach the end of this post, you will have a deeper understanding of the human eye and also be able to squash a few pesky myths when they pop up on social media.

We think that piecing together posts like this helps to dispel the myths and nonsense that flies around the internet and attempts to supply you with nonsense information and give you a false understanding of things.

So, if you would like to gain a little more clarity on the human eye, we are hoping that this post will help you see things more clearly.

Your Vision May Not Be As Great As You Think

So, the first thing we are going to be looking at today is that age-old belief that your vision is perfect if you have 20/20 vision.

While television, film and hearsay would have you believe that you have perfect vision, the facts, on the other hand, say differently. First of you need to understand what 20/20 vision actually means, and that’s quite simple to explain.

When somebody tells you they have 20/20 vision, they are referring to their visual acuity or the sharpness of their vision. The first number refers to the distance from the eye chart the patient is when tested; for example, 20 feet. 

If you can read the normal range of letters on the eye chart, this would mean you have 20/20 vision. If you can read the lower lines, you would have 20/15 vision and the lowest line you would have 20/10 vision.

Of course, this also works the other way and should you only be able to read the top line of the eye chart from 20 feet away, you would have 20/40 vision. 

From this explanation, you should be able to see clearly that when it comes to having an average vision, 20/20 is about as average as you can get. So next time somebody tells you that you have 20/20 vision, you will know that this does not mean they have perfect vision.

It’s Highly Possible That You Will Need Glasses

Ok, so you may be reading this without a second thought, and you may believe you have outstanding vision, but the truth is, this is only right now.

By the time you reach the tender young age of forty. Your eyes will start to experience a condition that is known as presbyopia. Presbyopia simply explained is the hardening of the lens of the eye, and when this occurs, it makes it very difficult to focus on any objects that are close.

When presbyopia starts, it will usually be a slow process, but over ten years or so you will notice that it gradually gets worse.

What may surprise is that around 85% of people will experience this in their lives, and they will need some form of corrective eye wear to help them see properly. 

If or when the time comes when you need glasses, you should make sure you choose carefully. While some people opt for something they like the look of, you should be looking at something like oakley glasses frames, or something similar. 

Well made frames can truly make all the difference when it comes to your first pair of glasses. While you may not realize it, acclimatizing to glasses is quite tough at first, so you should look for something that will be very comfortable.

Carrots Aren’t All They Are Cracked Up To Be

It matters not how old you are, at some point in your life you have either heard somebody say, or said yourself that carrots are great for your eyes and they will help you see in the dark.

Well, it seems there is a little truth in this, but not really as much as you’d think. While the vegetable that is rich in beta-carotene is a fantastic addition to your daily intake of fruits and vegetables, it has no specific benefits to the eye itself.

The only way carrots are able to support eye health is by a converted base of vitamin A that is supplied when the body converts beta-carotene in the body.

In truth, if you really want to improve your eye health, then you will be better served with a diet of oily fish and green vegetables that are rich in zeaxanthin and lutein. 

If You Want To See If The Dark…Wear An Eye patch

Following on from the last fact, when it comes to seeing better in the dark, well, it’s all a matter of allowing your eye to adjust to the dark. 

So, here is something you may, or may not have known. The eye patch has become synonymous with pirates, but why did so many pirates have a missing eye? Well, it seems that many of them probably didn’t.

The truth has been found to be something far smarter than the covering of the hole where their eye used to be. 

After many years of research, it seems that pirates simply wore an eye patch in preparation for a fight. If a pirate found himself in a one on one swashbuckling battle, he would lure his opponent into the pitch-black depths of the galley.

Once there, the pirate would simply switch the eye the patch was on, and he’d be able to see far better than his opponent who would still need a good 5-7 minutes to get used to the dark.

While this may seem far fetched, think about it this way. If you wake up in the night in a pitch-black room, your eyes will have acclimated to the dark while shut that you can see, it’s the same thing.
