15 amazing facts about eyes


Our eyes are incredibly fascinating and complex. There is always something new to learn about them and in this article, we bring you some amazing facts about them.


  1. Ultra Speed: The average blink lasts for about 1/10th of a second, making your eye muscles the fastest in your body.
  2. Ever Vigilant: Before any kind of activity or even just after waking up, it takes some time for most parts of your body to warm up to their full potential, but your eyes are on their “A game” 24/7.
  3. Super Healing Ability: Eyes heal incredibly fast. With proper care, it only takes about 48 hours for the eye to repair a corneal scratch.
  4. High Brain Power: Seeing is so crucial to how we function that it engages and involves up to 50% of the brain.
  5. I cry the Dry Cry: Newborns don’t produce tears. They make crying sounds, but the tears don’t start flowing until they are about 4-13 weeks old.
  6. Sightless: Around the world, about 39 million people are blind and roughly 6 times that many have some kind of vision impairment.
  7. Mission Impossible: Doctors have yet to find a way to transplant an eyeball. The optic nerve that connects the eye to the brain is too sensitive to reconstruct successfully.
  8. Team Efforts: The cells in your eye come in different shapes. Rod-shaped cells allow you to see shapes, and cone-shaped cells allow you to see colour.
  9. Bat Those Eyelids: You blink about 12 times every minute.
  10. Size Matters: Your eyes are about 1 inch across and weigh about 0.25 ounce.
  11. Pretty Colours: Some people are born with two different coloured eyes. This condition is heterochromia.
  12. Behind the scenes: Even if no one in the past few generations of your family had blue or green eyes, these recessive traits can still appear in later generations.
  13. Blind Spot: 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.
  14. Hyperactive: Out of all the muscles in your body, the muscles that control your eyes are the most active.
  15. Easy to fix: 80% of vision problems worldwide are avoidable or even curable.

Eyes are incredibly fascinating in how elegantly they function. Remember to take care of your eyes and keep them working at their absolute best. Book an eye test today and get a good start on making sure your eyes stay amazing.
