EYE FUNCTION

Blinking helps remove any debris on your eye’s surface by

spreading tears over them. The tears help moisten and lubricate

the eyes and they also have important anti-bacterial properties.

 

 

EVERYBODY GETS CATARACTS AS THEY GET OLDER

You could think of cataracts as having similarities to getting grey hair

in that it’s just a normal, natural change as you age. The average age

people first get cataracts is around 70 years old.

 

 

DIABETES IS OFTEN FIRST DETECTED DURING AN EYE EXAM

Those who suffer from type 2 diabetes are often symptom-free,

meaning they don’t even know that they’ve got it. This type

of diabetes is normally picked up during eye exams as it could

be seen as small haemorrhages from leaking blood vessels

at the back of the eye.

 

 

YOU SEE WITH YOUR BRAIN, NOT YOUR EYES

This may sound obvious but many times blurry or poor vision isn’t caused

by the eye at all. The poor vision stems from something going wrong in

the visual cortex of the brain. There’s a lot that can go wrong with the

ocular system.

 

 

YOUR EYES CAN ADAPT TO BLIND SPOTS

Specific eye conditions (e.g. glaucoma) could lead to blind spots in your

vision. This can prove to be immensely debilitating if it wasn’t for the

brain and the eyes abilities to adapt, making such blind spots disappear,

similar to the way it adjusts the upside down vision we mentioned earlier.

It does this by “suppressing” the blind spot in your affected eye and

allowing your good eye to fill in any “blanks.”

 

 

20/20 VISION IS NOT THE BEST VISION

In a typical eye test chart, 20/20 vision is the line that’s second from

the bottom. The line that’s below it is even smaller and if you can see it,

this means you have 20/16 vision. The best recorded human vision,

however, was 20/8 which means you could see what normal people

see at 8 feet at 20 feet.

 

 

YOUR EYES WATER WHEN THEY’RE DRY

Tears are made up of three different components, namely fat, mucus

and of course, water. If these three components aren’t exactly in their

right quantities, your eyes could become dry. Your brain responds to

such dryness by producing more of them!

 

 

EYES HEAL QUICKLY

With the proper care, it will only take around 48 hours for the eye to

repair a corneal scratch.
