Random Facts About Your Eyes
Our eyes are absolutely amazing if you stop and think about their capabilities! They filter light and images so we can see the world around us. They send messages to our brains about what we see. On top of that, they even have a self-cleaning function.
How much do you really know about your eyes?
Here are some random facts about your eye that will really surprise you!
- Eye size: You can probably guess the length of your eyes. On average, an eyeball is about one inch across. But did you know that each eyeball only weights ¼ of an ounce? That’s the same weight as just a penny and two dimes! When you’re looking someone in the eye, know that only 1/6 of their eye is exposed. In other words, most of our eyeballs are never seen.
- Blinking: Blinking is your eye’s natural way of getting rid of debris and clearing the lens. Did you know that you blink 12 times every minute and that the average blink only lasts 1/10 of a second?
- Eye Muscles: Here’s a great piece of trivia for you. All the other muscles in your body need a bit of a warm-up before exercise. Not your eye muscles! They are ready to go, 24/7. No warm up necessary for this muscle group!
- Blind Spots: Everyone has a blind spot. The reason? The spot where the optic nerve and the retina connect is unable to “see” anything. Most of us don’t notice this blind spot because our eyes work together to fill in the missing space.
- Eye Development: Your eyeballs start to develop only two weeks after conception. This is one of our favorite random facts! Amazingly, your eyes stay the same size from birth to death. Your ears and nose grow, but not your eyes. If you’ve ever wondered why it seems like babies have such big eyes, now you know why!
- Eye Transplants: The eye cannot be transplanted! There are more than one million nerve connections in the back of the eye making an eye transplant virtually impossible.
- Eye Healing: Your eyes are one of the fastest healing parts of your body. Even something as potentially serious as a corneal abrasion can heal in about 48 hours.
- Blindness: There are 39 million blind people in the world. Unfortunately, up to 80% of all vision-related problems could be avoided or prevented.
