The eye is one of our most important sensory organs for orienting ourselves in our environment. In its structure and functioning, the eye can be compared to a camera lens: Light rays pass through the transparent surface of the eye - the cornea - through the pupil.
The size of the pupil, and thus the amount of incident light, is regulated by the iris. The incident light rays are then bundled by the lens behind it and projected onto the retina. There, the light is converted into nerve impulses that are transmitted from the optic nerve to the brain. By combining the images of both eyes, we are able to see spatially.
Anatomy of the human eye
Optic nerve (lat. Nervus opticus) in the eye
The optic nerve is responsible for ensuring that information from the retina reaches the brain. The concentrated bundle of millions of nerve fibers converts the light stimuli from the retina into impulses and sends them to ...
Inner eye shell
The inner shell forms the retina. It is used to receive light stimuli. The light impressions are transmitted to the brain via the optic nerve and processed there.
Blind spot (papilla)
The so-called blind spot is the point in the eye where the retina is interrupted and merges with the optic nerve. Since there are no light receptors at this point, ...
