What is your favourite colour?! Thanks to our eyes that help us recognise colours. Let’s discover five interesting eyes facts for kids.

We blink so many times in a day that we barely even notice when we do. Which is a good thing considering we do it more than 10,000 times a day. But why do we blink? Our eyelids are like windscreen wipers. When it rains, you turn the windscreen wipers on to clear your view and keep the rain off the windscreen. In the same way your eyelids blink in order to spread fluid over your eyes to keep them moist  and they keep bacteria and dust out of your eyes. Your eyes blink in ⅖ of a second. That is very very fast!

Eyes Facts for Kids Fact Number 2: Your Eyes See Everything Upside Down and Backward

Did you know that our eyes actually see everything upside down and backwards. Thankfully, our brain flips images that our eyes see right side up and allows us to see images and objects as they are. Our eyes also see every object as a two-dimensional shape and our brain transforms these images into three-dimensional shapes for us. Can you imagine if our brain didn’t fix this problem? It would be hard to live in an upside down flat world.

Eyes Facts for Kids Fact Number 3: Your Pupils Are Changing Sizes to Protect Your Eyes

Next time you go from a dark room to a bright room or vice versa, look at how your pupils change in size. Your black pupils grow and shrink to allow the right amount of light to enter your eyes so that  you can see. In bright light, the iris, which is the colourful part of your eye, makes the pupil small to protect your eyes from too much light which can hurt your eyes. In darker light, the pupil gets bigger to allow more light in so that you can see better.

Eyes Facts for Kids Fact Number 4: Some People Have Different Coloured Eyes

Some people have different coloured  eyes. This unusual condition is known as  heterochromia This can occur from injury or trauma to the eye or a person can be born with it. More people have brown eyes than blue. You probably have the same colour eyes as one of your parents. Some famous people who have heterochromia are Henry Cavill, who plays Superman and the Irish dancer Michael Flately, who has one brown eye and one blue eye.

Eyes Facts for Kids Fact Number 5: The Shape of Your Eye Determines How You See

Some people are near-sighted or far-sighted. People who are near-sighted, can see things that are near or close to them but can’t see things that are far away. People who are far-sighted can see things that are far away and at a distance but they can’t see things close up. This happens because the eyeball is either too long or is flattened. People wear glasses or contact lenses to fix these problems.
