How well do you know your eyes-the fastest muscle in your body?
Well, why don't you check the fun facts below and see for yourself what you do and do not know about this marvelous body organ that allows us to appreciate our beautiful planet.
Fact # 1: Our eyes consist of over 200 million functional parts.
Wow. Think of that! The average eye is only two-thirds as big as a ping pong ball. Now try squeezing in over 200 million functional parts and you can just imagine how amazing our eyes are.
Fact # 2: Given the right weather and light conditions, a person with a normal vision can see a candle's light that is some 14 miles away.
We are speaking about a person with a 20/20 vision here. But, just think of that! The structure of our eyes is so amazing that it could detect even a speck of light from a far distance!
Fact # 3: Our eyes can see not just 50 but 500 shades of grey.
We are pretty sure that prior to reading that line, you were not aware that there are 500 shades of grey. But yes, there are 500 shades of grey, and the fact that your eye can distinguish the difference between those shades is a marvel itself.
Fact # 4: No one has a black eye color.
No matter what you think, your eyes can only be as dark as the darkest brown but it is never black. In fact, brown is the most common eye color in the world.
Fact # 5: Every year, you blink your eyes at least 4,200,000 times.
Of course, you have not thought of counting how often you blink, but that figure is there to give you an idea of how much your eyes blink. Why do we blink? Blinking helps the eyes to 'breathe' oxygen and also provides moisture. So, if you frequently stare at a computer screen, you are most likely to stress your eyes out easily since your eyes do not blink as often as it should.
Fact # 6: Your eye's cornea does not contain any blood vessel.
Your cornea is the thin transparent membrane that serves as your eye's window to the world. It is the primary eye structure that focuses the light that enters your eyes. The reason for the cornea's transparent structure is its absence of blood vessels. However, it contains many nerve fibers that make it very sensitive to pain.
Fact # 7: Smokers have poor night vision.
Smoking is the single major addiction that could bring so much trouble to your body. Each cigarette contains hundreds of chemicals that destroy different body organs, including the eyes. Those who smoke a lot destroy so many optical cells, making it difficult for them to see well in the dark as a normal person would.
Fact # 8: Having two eyeballs helps you perceive depth accurately.
The images that each eyeball generates in the brain allow for comparison and determining how far or near an object is from you. Those who only have one eyeball, naturally, will have a hard time determining an object's distance and depth accurately.
Given the eight facts about the eyes, we can thus conclude that our eyes are indeed a brilliant structure. What can we do then to make sure that we take good care of it? Health experts recommend good nutrition to keep our eyes healthy. Eat foods rich in lutein, beta-carotene, Vitamins C and E, and other essential vitamins and minerals! You may also consider taking in dietary supplements like spirulina supplements to fill in any nutrition gap you may have. Also, do not forget to allow your eyes to rest. If your job involves staring at a computer screen, make sure that you take a break from the computer every 20 minutes. If you need to be under the sun frequently, always wear sunglasses.
Take care of your eyes; they are not only the windows to your soul but also your windows to the world.
