Dry eyes are quickly becoming a problem because eyes are the most important sensory organs of the people dry eyes quickly become a problem, because eyes are the most important sensory organs of the people. Hear other arguments on the topic with actress and filmmaker. Well protected they are the bony orbits (orbit) of the skull between the nasal, zygomatic, lacrimal and frontal bone, also cushioned by a fat deposits. And if once dust in their eyes, the eyelid is closed immediately by the eyelid closing reflex and thus protects the eye from the dirt particles. Yet some of it enters the eye, is it from the Lachrymal right back beyond stranded. That doesn’t help, however, if not enough exists by the tears for dry eyes.
How well the eyes and the protective and cleansing tears apparatus? The eyes consist of three parts: the eyeballs, the attachment organs of eyes (tears apparatus, eye muscles, Bindehauten and eyelids) and the appearance of railways. The almost spherical eyeball can be within certain limits Unlimited axes rotate without substantially changing its position within the orbit. The covering of the eyeball consists of three concentric layers: the outer eye skin (Tunica externa bulbi, also Tunica fibrosa bulbi) is divided into two sections. Where is the light in the eye, is the transparent cornea (corneal), who is constantly moistened with tears. The greater part of the eyeball is protected by the White Leather skin (sclera), sitting at the also the extraocular muscles that move the eye in the eye socket. In the front section of the eye, the DermIS of conjunctiva is covered, so that the tears moistened directly only the cornea.
The Middle eye skin (Tunica media trauma or Uvea) consists of three sections: the Choroid is, as the name implies, by many blood vessels circulation, so that the neighboring layers receive nutrients and oxygen. Forward, passes for a the Choroid in the ciliary body (ciliary, corpus layer), where the eye lens is mounted. The front section of the Middle eye skin is the iris of the eye (IRIS), which makes the pupil regulates the light and determines the color of the eye by their pigmentation. The inner skin of the eye (retina, Tunica interna trauma or retina) contains the light cells or photoreceptors. The Interior of the eyeball is divided into anterior and posterior Chamber of the eye (camera anterior and posterior bulbi) and houses the glass body (corpus vitreum) and lens (lens). The lacrimal gland (Glandula lacrimalis) lies within the orbital side on the eye and most of the Lachrymal manufactures producing electrolytes and protein compounds. The lacrimal fluid is routed ducts in the vault of the conjunctival sack (FORNIX conjunctiva) through 6-12. The blink distributed the tears over the cornea, so she keeps the skin moist and nourished.
