How Does The Human Eye Actually Work?

How Does The Human Eye Work
This question is very basic, and also one which ties all of humanity. Strangely Yet, very few people actually possess the knowledge of how the eye works.
So, lets teach you why you see, what we see! (abit of a tongue twister)
Firstly, let’s introduce what makes up a human eye.
Cornea – The guardian and protector of the eye, who keeps foreign objects away from it. The Cornea admits light and initiates the refractive process.
Pupil – This controls the intensity of the light striking the lens.
Lens – The Lens focuses the light through vitreous humour- a gel-like material. The vitreous humour supports the retina.
Retina – The retina is responsible for receiving the image and transforming it into electrical impulses. These impulses are then brought to the brain via the optic nerve.
Light– It’s all about light. There is a reason r we cannot see in darkness!, without this our eyes are pretty much useless.
How do eyes work
Vision – The Process of Seeing
To understand this better, we have divided it into steps.
Step 1 – The light from an object reflects and enters into the eye.
Step 2 – The light enters through cornea. It controls the amount of light permissible to strike the lens.
Step 3 – The light is then focused as per shape and distance by the lens, which works just like the lens of the camera.
Step 4 – The light enters the clear jelly-like vitreous humour and reshaped
Step 5 – The image then enters the retina. It transforms the image into electrical impulses. It sends the image to the brain as electrical impulses via the optic nerves.
And just like that, one can see.
