Our eyes
The human eyes are a highly developed sensory organ. Healthy eyes can perceive information in the range of visible light. With the eyes we can orient 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 center 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 front ...
Conjunctiva (lat. Tunica conjunctiva) & Eyelid
The conjunctiva "connecting garment" (lat. Tunica 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, 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 eye chamber (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 humor - 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): Eye hole of the eye
The pupil is the circular aperture in the center of the iris. Light enters the interior of the eye through the pupil. Its size is regulated by the surrounding iris, depending ...
Rainbow skin (lat. Iris)
The iris is the colorful part of the eye and is as individual as a fingerprint. The so-called iris, or "colorful 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 humor and regulates the curvature of the lens for near or ...
