The facts behind your amazing eyes

Posted by ?> | Eye Condition, Eye health, Eye Test | 0 |


It’s pretty safe to say that most of us usually take our eyes and eyesight for granted. But when you stop and think about it, your eyesight is an amazing thing. Without it your life would be completely different – for example, 80% of our memories come from what we see.

At Eye Emporium we’ve compiled some facts about your eyes and vision that we hope you’ll find interesting.

Did you know?

Your eyes contain around 200 million working parts, 107 million light sensitive cells, 7 million cones to help you see colour and details, and 100 million cells to help you see in the dark.

Each hour your eyes can process 36,000 pieces of information, and the muscles in our eyes are 100 times stronger than they need to be to function properly.

Your iris has 256 unique characteristics; that’s 216 more than your fingerprint, which is why retinal scanning is increasing in popularity.

In an average lifetime, you will see 24 million different images – that explains why so much of our memory comes from what we see.

We each blink around 4,200,000 times each year; more often when we talk, and less often when we use a computer or read. Each blink lasts between 100 and 500 milliseconds, and it’s possible to blind 5 times in one second – try it!

The eye

The colour of your eyes is down to the amount of melanin in your iris. Brown is the most common eye colour in the world, and blue eyes date back about 10,000 years. Blue eyed people share a common ancestor with every other blue eyed person in the world. Some peoples’ eyes are different colours; this is called heterochromia.

All babies are colour-blind at birth, and men are more likely to be colour-blind than women.

Every 5 seconds someone in the world goes blind. Every day, someone in the UK starts to lose their sight.

Diabetes is the most common cause of blindness in the UK and there are almost 2 million people in the UK living with sight loss. Over 50% of this sight loss could have been prevented.

86% of people value their eyesight over any other sense.

Around half of all blind or partially sighted people in the UK feel moderately or completely cut off from people or things around them.

Vitamins A and C, and omega oils all help to preserve good eye health, so eat lots of green leafy veg, fruit, and oily fish and eggs. Regular visits to an expert optician also help to keep your eyes in good health.

An eye examination does more than just test how well you can see. It can also detect issues with your general health such as high blood pressure, diabetes, and even tumours.


At Eye Emporium we advise that you have your eyes examined once a year, unless you’re recommended to be seen more frequently. This will help to ensure that everything is in full working order and that there are no slight changes that could go on to cause a problem. If you do have something wrong, it’s better to spot it early so that treatment is successful.
