Light enters the eye through the cornea, where it is then transmitted to the lens and pupil. The cornea is therefore also called the "window of the eye" and is an important component of the optical system.
The refractive power of the cornea is quite strong at about 43 diopters and is thus an important factor in producing an image on the retina. Due to its evenly arranged and fine tissue structures, the cornea is transparent and forms a crystal clear dome on the surface of the eye. It is protected by the eyelids.
Corneal curvature
Many people have astigmatism - a natural irregularity of the cornea. This can be corrected with glasses and contact lenses, but also with laser eye surgery and the use of an artificial lens.
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, ...
