How the Eye works!
Important parts of the eye.
Cornea - This is the see-through skin that cover the front of your eye. It is transparent and has no blood vessels in it.
Iris - The Iris is the part of the eye which is coloured. It can be blue, brown, black, green even grey. The Iris controls the amount of light the gets let into your eye
Pupil - This is the hole inside the Iris. Light goes into the Pupil, and when there is a lot of light. Your Pupil becomes small and when there is not a lot of light. The Pupil gets big because it needs more light to see clearly.
Lens - When light goes through the pupil, it goes through the lens as well. It’s job is to focus light rays on the back of your eye.
Retina - This is the back of your eye. It contains millions of cells that are light sensitive. The retina takes the light signals and changes them to nerve signals.
Optic Nerve - This is connects your eyes to your brain. This is where the signals from the retina get sent through.
These are only some of the most important part of your eyes.
Why is the tree upside down?
In this photo, why is the tree upside down? Well, when you look at things the eye thinks it is upside down however when the eye transmits the image to the brain. The brain corrects it and it shows you what you are looking at. For the brain, it is a complex task to process visual information. This takes up a big portion of your brain (more than other senses) because it performs several tasks to make images easier to see.
