Watch out for your mascara! (See #5)
I’m the type of person that loves a good fun fact. I like knowing things and I love learning about the industry that I’m in. Here are a few more interesting things about the eyes…
- Everyone around the world with blue eyes shares a common ancestor: the first person with blue eyes lived around 6,000 – 10,000 years ago, and before that, everyone had brown eyes.
- If you wore glasses that flipped images upside down, your brain would eventually correct your vision, and you’d see things the right way up.
- Some eye surgery uses shark corneas, as they are the most similar to a human cornea.
- Your nose runs when you cry due to tears from your eyes draining into the nose.
- Mascara wands cause the most injuries out of any cosmetics.
- The muscles that move the eyes are the fastest and strongest muscles in the body: they are 100 times more powerful than necessary.
- You blink more when you talk, and less when you’re reading off a computer screen or paper – the reason behind why your eyes get tired more.
- People generally read 25 times slower on screen than on paper.
- The human eye can see 500 shades of grey.
- New-born babies are color-blind, and men are more predisposed to color-blindness than women.
- Retina scans are being used more for security purposes: the fingerprint has 40 unique characteristics, whereas an iris has 256.
- Pupils increase their size under the effect of strong emotions, such as attraction, disgust and interest.
- The eye has amazing healing powers: it can filter out dust, dirt and heal scratches in under 48 hours.
- Eyes are the second most complex organ in the body, after the brain.
- The function of tears is to keep the eye clean, but scientists haven’t yet worked out why we cry when we’re upset.
- One blink usually lasts around 100 – 150 milliseconds, and we blink 5.2 million times a year on average.
- Over 10 million color hues can be detected by the eye, but it can’t pick up ultraviolet or infrared light.
- Around half of the brain is used for seeing and vision.
