Not unless something goes wrong and our vision is significantly affected, we often do not give our eyes as much attention as we should. However, if you learn more about our eyes, you will understand just how amazing they’re.
Our eyes are one of the most complex and fascinating parts of a human body. Nearly each animal in the animal kingdom depends on them daily, but how much do we really understand about our eyes, and how they function?
You should ask yourself though-how well do you understand the functionality of this remarkable organ? For example, did you know that each time you light up a cigarette, you’re lowering your night vision? Or that an average blink usually lasts 300 to 400 milliseconds?
Human beings are very visual species. The high amount of information is often stored in our brain through our eyes. On the other hand, it’s also a mode of expressing our feelings and emotions.
Though often take it for granted, the phenomenon of vision is one of the greatest gifts we’ve only by virtue of being strong members of the human race. Consider some basic things such as watching our favorite sports teams, viewing excellent works of art and seeing a deer in the wilderness enrich our lives in entirely immeasurable quantities.
As one of the highly complex organs in the body and scientists still discovering more about it, the eyes continue to surprise us over and over. That is why some scientists have even considered it a wonder of nature.

1. The eye muscles are the strongest in a human body
The eye’s exterior muscles are remarkably large relative to the small weight and size of an eyeball, and they’re the strongest muscles for the work they do. These muscles are strong because they always move to change the position of the eye even when the head is moving.
Since we always move our eyes during the rapid eye movement sleep (REM), eye muscles also when we are sleeping. Therefore, these muscles work restlessly. The muscles of the eye, though, are subjected to fatigue too. Actually, this is the primary reason why our eyes need some rest after working continuously for one hour.
2. After the brain, the eye is the most complex organ in the body
Apart from the brain, the eye is the most complex organ of a human body. Every eye consists of 12 million photoreceptors. They work in conjunction with the brain that is always interpreting and analyzing the information it receives from them.
3. Eating carrots won’t boost your night vision
Throughout our lives, we have heard, or we have been thought that eating carrots enhance out night vision. Unfortunately, this is a misconception.
Essentially, carrots are rich in beta-carotene, (that the body utilizes to distribute Vitamin A to our eyes), but they will not boost your night vision. Nonetheless, the taking them as part of a healthy diet is good for your ocular health.
4. Your eyes do not need to rest
Your eyes can operate day and night, without any rest. But, like all other muscles in your body, the eyelids must rest at the end of each day. Remember, they blink about 12 times per minute, up to 10000 times per day!
5. We blink 25000 times per day
Magnificent, isn’t it? Blinking has two major purposes-to protect the eyes from any foreign particles and to keep the eyes lubricated. Our eyelashes have short and curved hair that acts as the dust-catchers. If they are exposed to any adverse elements, the blinking reflex causes them to lower automatically.
6. Your eyes are quicker and sharper than any camera
You can experiment this at home: just focus on many objects as possible which are at positioned at various distances from you. See how fast they can switch focus? A typical camera may take many seconds to accomplish this task. Incredible!
7. Everyone will require reading glasses at some point in their life
About 99 percent of the population between 43 and 50 years old requires reading glasses. Due to the occurrence of the natural aging process, the eyes goes from a flat shape to a spherical one leading to the loss of some of their capacity.
Therefore, it is highly recommended that you visit your optometrist regularly in your 40s. A specialist can assess and fix any vision problems you may be experiencing.
