Cornea
Cornea (lat. cornea) is the front transparent part of the outer eye membrane and is also the first optical medium that light rays reach on the way through the eye.
White eye
The sclera or sclera (lat. sclera) is a white, opaque membrane that forms the larger, posterior part of the fibrous sheath of the eyeball.
Pupil
The pupil is located in the very center of the iris (it is black in color), it forms a round opening through which light passes to create the image we see
Iris
The iris or iris (lat. iris) is the front part of the middle membrane of the eye, the most impressive for the fact that it contains the pigment that determines the color of the eye, and prevents the entry of excessive amounts of light into the eye like the shutter in a camera
Žilnica
The choroid or chorioidea (lat. chorioidea) covers the entire inner side of the white of the eye (sclera) from the ray body to the back, i.e. it is located between the white of the eye and the retina
Retina
The retina is a very delicate, photosensitive membrane that lies on the inside of the eyeball.
Radiant body
The radiating body or ciliary body (lat. corpus ciliare) is ring-shaped and is located on the inside of the sclera a little behind the iris
Eye lens
The eye lens (lat. lens) is a transparent body that is located in the eye directly behind the iris, in front of the vitreous body, and occupies most of the posterior chamber.
The eye is a paired organ of vision located in the eye cavity. The eye cavity or orbit (lat. orbit) is bounded by several bones that surround the eye from all sides except the front, thus mechanically protecting it.
The eyeball or bulbus (lat. bulbus ) consists of the outer eye membrane, the middle eye membrane and the inner eye membrane, as well as the eye lens and the vitreous body that fill the bulb. In the eyeball there are two eye chambers that are filled with aqueous humor .
The outer sheath of the eye ( tunica fibrosa bullbi-externa ) consists of the cornea (cornea) and the sclera (sclera) . The outer covering of the eye ( tunica fibrosa bulbi ) represents the skeleton of the eyeball and is made of solid connective tissue. It determines the shape and size, serves as a grip for the muscles and protects its parts.
The middle layer of the eye ( tunica vasculosa bullbi ) consists of the choroid ( chorioidea ) , the iris ( iris ) and the ray body ( corpus ciliare ) . The name tunica vasculosa bulbi indicates that this sheath is full of blood vessels. The largest part of the middle layer of the eye is the choroid – the choroid .
The inner covering of the eye ( tunica nervosa – interna ) consists of the retina. The retina is divided into pars optica retinae and pars coeca retinae . Clinically speaking, the retina has two parts – the outer layer of the pigment epithelium and the inner layer of the pigment epithelium.
The eye lens (lat. lens ) is a transparent body located in the eye directly behind the iris.
The vitreous body, vitreous or vitreous (lat. corpus vitreum ) fills the entire interior of the eye behind the lens to the inner surface of the retina.
We divide the eye chambers or chambers into the front eye chamber ( camera bullbi anterior ), which is bounded in front by the cornea, and the back by the iris and lens, and the back eye chamber ( camera bullbi posterior ), the space behind the iris which is bounded by the vitreous body in the back. The eye chambers are filled with a liquid called aqueous humor (lat. humor aqueous ).
The creation of vision begins with the arrival of light rays from the object we are looking at, they enter our eye passing through almost all its structures. After passing through the cornea, the anterior chamber and the pupil, the rays pass through the eye lens. The eye lens has the ability to accommodate or focus light rays exactly on the retina or the place of the clearest vision – the macula. After a whole series of chemical changes, the nerve cells of the retina are activated. Nerve cells conduct electrical signals that go via the optic nerve to the visual center of the brain, where an image is finally created, with which a person analyzes the outside world.
