The human eye or eyeball is the organ of sight. It is shaped like a slightly flattened sphere and the way it works is very complex, often compared to the workings of a camera.

The human eye

How does it work?

The eye obtains information about its surroundings through lightsmall parts works in synergy with the others to visualise the world around us, transmitting messages to the brain, which is then able to interpret the various messages.

The light reaches the iris, which filters the intensity and helps the lens and the vitreous in the focusing process. This first process enables the retina to transform light into electrical signals, which are used to process images with the help of the optic nerve, the brain’s messenger.
