The human eye is the second most complex and powerful body part next to the brain. Here are 10 amazing facts about our eyes:
Number 10 – Eyes begin developing their more than 2 million working parts a mere 2 weeks after conception.
Number 9 – They stay the same size from birth while the ears and nose continue to grow throughout life.
Number 8 – Though brown eyes with more pigment in the iris are most common, blue-eyed people have a common ancestor.
Number 7 – The eye’s transparent cornea allowing light to enter the eye is the only body tissue without blood vessels.
Number 6 – Along with superior protection, the eyes can clear out foreign material and heal scratches often within 48 hours.
Number 5 – The eye blinks anywhere from 2 to 50 times per minute, which averages out to more than 4 million times per year.
Number 4 – Eye scans are increasingly used for security because the iris has 256 unique attributes while fingerprints only have 40.
Number 3 – Despite the saying “rest my eyes,” eyes are the only body parts that don’t need any rest; it’s actually the eyelid muscles that need breaks.
Number 2 – Not only is the eye muscle the body’s fastest and most active, but it’s 100 times stronger than it needs to be for its function.
Number 1 – Seeing only in red, blue, and green, the eye can identify more than 10 million color combinations, including 500 gray shades.
