Everything that is made beautiful and fair and lovely

is made for the eye of one who sees.

Rumi

Human eyes are one of the most fascinating and complex parts of the body. We don’t give our eyes as much attention as we should until something goes wrong or when the vision is affected.

We have collected few important facts you may find interesting:

1. Blinking

The average person blinks some 15-20 times per minute—so frequently that our eyes are closed for roughly 10% of our waking hours overall. (Image Source)

The muscle that control blinking movement is the fastest in the human body. Did you know that average adults tend to blink  once every 5 seconds, which adds up to an exhausting 6,5 million times a year.

2. Blind spot

It is in this region that the optic nerve exits the eye on its way to the brain. To find your blind spot, look at the image below or draw it on a piece of paper (Image Source)

Each of your eyes has a small blind spot in the back of the retina where the optic nerve attaches. You don’t notice the hole in your vision because your eyes work together to fill in each other’s blind spot.

3. Drinking

Ever notice how bloodshot your eyes look after a night of drinking? (Image Source)

The eye colour can be an indicator of how well you handle alcohol beverages. A study from Georgia University shows the people with lighter eye colour (blue, green, grey or hazel) took their drink beer that people with darker eyes colour.

4. Political leanings

A new study suggests that liberals are more likely than conservatives to follow other people's eye movements. (Image Source)

It is difficult to believe but you can tell someones’s political view from their gaze. People that lean to the left of the political spectrum will follow ‘eye cues’ more readily than conservatives. Be aware, if you are chatting with liberal, it is most likely they will trace your gaze should your eyes stray from theirs.

5. Flirting

Want to know the perfect way to catch someone's attention and make them interested in you? Use these eye contact flirting moves that definitely work. (Image Source)

Eye contact during flirting can take a variety of different forms including the long gaze that signals romantic or sexual desires, or staring into someone’s eyes for a few seconds then breaking eye contact to look them up and down or at a particular part of their body and then back in their eyes.

6. Lying

It shows the various directions of eye movements of a person and explains what is usually going on in their mind at that moment. (Image Source)

If you want make sure somebody is telling truth you need to look into their eyes. If they look upwards and slightly to your left, then it is most likely you are hearing lies. If somebody is just recalling the information, they eyes will be looking completely other way.

7. Focusing

Our eyes have an automatic focusing system which adjusts the lens inside our eye in order to see clearly at all distances.

It’s crazy how much the focusing muscle of the eye gets done. On an average, this spectacular muscle of the human eye moves about 1000,000 times every single day. If that doesn’t blow your mind, let’s put it in perspective. For your leg muscles to get the same kind of workout, you would have to walk 50 miles, every day.
