Our eyes

The human eyes are a highly developed sensory organ. With healthy eyes, information can be perceived in the range of visible light. With the eyes we can orientate ourselves in the environment.

Aug compared with a camera

The cornea and the lens correspond to the objective and focus the incidence of light on the centre of vision. The iris corresponds to the diaphragm and regulates the incidence of light into the eye. The retina corresponds to the film.

Anatomy of the human eye

Human eye

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 ...

Outer eye shell

The outer shell is formed by the transparent cornea and the opaque white sclera. Both tissues give the eye its shape and strength. The conjunctiva covers the sclera in the front ...

Conjunctiva (lat. Tunica conjunctiva) & Eyelid

The conjunctiva is a mucous membrane of the anterior segment of the eye and surrounds the cornea and the visible white part of the eye. With each blink of the eye, the conjunctiva distributes ...

Ciliary muscle (lat. Musculus ciliaris)

The ciliary muscle belongs to the inner eye muscles and is located in the ciliary body (lat. corpus ciliare) - also called the ray body. The ciliary body is a section of the middle eye skin and, besides the suspension ...

Posterior chamber of the eye (lat. Camera posterior bulbi)

The posterior chamber of the eye is smaller than the anterior chamber. It extends from the iris to the vitreous body - in it lies the lens. The aqueous humour - which covers both the posterior ...

Cornea (lat. Cornea)

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 a ...

Pupil (lat. pupilla): visual hole of the eye

The pupil is the circular aperture in the centre of the iris. Light enters the interior of the eye through the pupil. Its size is regulated by the surrounding iris, depending on ...

Iris (Latin for iris)

The iris is the colourful part of the eye and is as individual as a fingerprint. The so-called iris, or "colourful aperture" of the eye, can be changed by an individual pigment distribution in ...

Middle eye shell

The middle shell consists of three sections with specific functions. The iris adjusts the incidence of light. The ciliary body produces aqueous humour and regulates the curvature of the lens for near or ...
