4. You see with your brain and not your eyes



The function of your eyes is to collect all the required information about the object you are looking at. This information is then passed from your eye to the brain via the optic nerve. It is the brain (visual cortex) where all this information is analyzed to enable you to ‘see’ the object in its finished form. This is not to say that your eyes don’t play an important role as they certainly do.

3. Your eyes can adapt to blind spots in your vision



Certain eye conditions such as Glaucoma and certain general health conditions such as having a stroke, can lead to you developing blind spots in your vision. This would be extremely debilitating if it wasn’t for your brain and your eyes ability to adapt to make these blind spots disappear. It does this by suppressing the blind spot in your affected eye and letting your other good eye ‘fill in the gaps’. It is adaptation like this that makes your eyes so resilient.

2. 20:20 vision is not the best vision you can have



When people hear the phrase 20:20 vision they assume that this is the best vision possible. However this is not true as 20:20 vision refers to what the average adult should be able to see. If you imagine a typical eye test chart the 20:20 vision is probably only the line second from the bottom. The line below it is even smaller than 20:20 vision and would mean you have 20:16 vision. So don’t be so impressed next time someone tells you they have 20:20 vision!

1. Your eyes water when they are dry



I know this might sound crazy but this is one of strange facts about your eyes. Your tears are made up of 3 different components and they are water, mucus and fat. If these 3 components are not in exactly the right quantities, your eyes can become dry as a consequence. Your brain responds to this dryness by producing extra water and hence your eyes water.
