10 surprising facts about your eyes
You never tend to pay a lot of attention to your eyes unless they are affected by some serious disorder or unless your vision is disrupted. But did you know that your eyes are capable of doing much more than you can imagine? here are 10 surprising facts about your eyes you didn't know about.
1. How intricate!
Your eyes take more than 2 million working parts to function. No wonder your eyes are the second most complex organ of your body after your brain.
2. A lot depends on them
As much as 80% of your memories are determined by what you see. Also, 80% of what you learn is because of your eyes.
3. Retina and security
The iris of your eyes has approximately 256 unique characteristics, which is more than even your fingerprints. This is the reason why retina scans are used so widely today for security purposes.
4. It's a colourful world
Your eyes can distinguish between approximately 10 million different colours. And women with a particular kind of genetic mutation can see millions of more colours.
The retina of your eyes receives the vision of the outside world as upside down. It is your brain, which flips the image for you so that you can see the world as it is.
6. Sunscreen for the eyes?
It is possible for your eyes to get sunburnt. Therefore, it is advisable for you to wear sunglasses in order to protect your eyes from the ultraviolet radiations.
The eye muscle is the muscle that reacts at the fastest rate out of all the other muscles in your body. It can contract in less than even 1/100th of a second.
8. Paint it red?
The retina of your eyes cannot detect the red colour. The retinas do have green, red and blue receptors, but the red receptor can detect only the colour yellow-green and the green one can recognise blue-green. It is your brain that combines these signals to give you the impression of the colour red.
9. Dreams and sight
Even if you become blind later in life, you can see images in your dreams if you were born with sight.
10. We are blink-eyed peas
You blink approximately 17 times every minute. That makes it 5.2 million times in a year.
