Having 20/20 vision does not necessarily mean you have perfect vision

Amazing Eye Facts

1.Having 20/20 vision does not necessarily mean you have perfect vision.

It only indicates the distance and sharpness of clarity, but doesn't include other vision skills such as peripheral vision, eye coordination depth perception, focusing ability and color perception.

2.Your retinas receive your vision of the outside world as upside–down.

Similar to how a camera functions, your brain flips the image for you.

3.There's a word for fear of eyes.

It's called ommatophobia.

4.Your eyes can get sunburned.

That's why it's important to wear sunglasses that protect you from UVA and UVB rays.

5.You not only see with your eyes, but also with your brain. The "visual processing center" is called the occipital lobe.

Found in the back portion of the brain, damage to the visual areas of the occipital lobe can leave a person with fractional or complete blindness.

6.Most blindness is preventable.

Through timely treatment and access to eye care, most visual impairment can be prevented, treated or cured.

7.80% of sensory information our brains receive is through our eyes.

Our visual system is a significant part of how we process information and a key factor in how we learn.

8.If your eyes are blue, you share common ancestry with every other blue–eyed individual in the world.

A genetic mutation affecting the OCA2 gene is the cause.
