You’ve had those peepers since you were born, so you may think you know them pretty well, but here are 10 eye facts you may not know.
- The average blink lasts for about 1/10th of a second.
- While it takes some time for most parts of your body to warm up to their full potential, your eyes are on their “A game” 24/7.
- Eyes heal quickly. With proper care, it only takes about 48 hours for the eye to repair a corneal scratch.
- 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.
- 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.
- You blink about 12 times every minute.
- Some people are born with two differently coloured eyes. This condition is heterochromia.
- 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.
- Out of all the muscles in your body, the ocular muscles are the most active.
- 80% of vision problems worldwide are avoidable or even curable.
