EYE FACTS
Added on: 18th Sep 2015
BLINKING HAPPENS TO BE AN ENORMOUSLY IMPORTANT
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.
