As with primates, human beings show an extreme alertness to where others are looking. Although a person may consciously control where his or her own eyes hover and land, he or she may feel compelled to look at objects and body parts which he or she finds interesting (e.g., faces, breasts, hands, and trees) -- or to gaze away from what he or she finds distasteful. In response to feelings of shyness, submissiveness, and stranger anxiety, we subconsciously "watch where we look". In crowded elevators, people generally avoid allowing their eyes to roam freely across others' faces as they do w ...

In the eye, the pupil is the opening in the middle of the iris. It appears black because most of the light entering it is absorbed by the tissues inside the eye. In humans and many animals (but few fish), the size of the pupil is controlled by involuntary contraction and dilation of the iris, in order to regulate the intensity of light entering the eye. This is known as the pupillary reflex. In bright light, the human pupil has a diameter of about 1.5 millimeter, in dim light the diameter is enlarged to about 8 millimeter. The ...

An eye is an organ that detects light. Different kinds of light-sensitive organs are found in a variety of creatures. The simplest eyes do nothing but detect whether the surroundings are light or dark. More complex eyes are used to provide the sense of vision. Many complex organisms including some mammals, birds, reptiles and fish have two eyes which may be placed on the same plane to be interpreted as a single three-dimensional "image" (binocular vision), as in humans; or on different planes producing two separate "images" (monocular ...

Body language is a broad term for several forms of communication using body movements or gestures, instead of, or as a complement to, sounds, verbal language, or other forms of communication. In turn, it is one category of paralanguage, which describes all forms of human communication that are not language. Paralanguage including body language has been extensively studied in social psychology. In everyday speech and popular psychology, the term is most often applied to body language that is thought to be involuntary, but in fac ...

The evil eye is a widely distributed element of folklore or superstition: a belief that some people, often women seen as witches, can bestow a curse on victims by the malevolent gaze of their magical eye. The effects on victims vary; some have them afflicted with bad luck of various sorts. Others believe the evil eye has even more baleful powers, that it can cause disease, wasting away, and even death. Some cultures hold that the evil eye is an involuntary jinx that is cast unintentionally by people unlucky to be cursed with th ...

Unconscious communication (or intuitive) is the transfer of information unconsciously between humans. It is sometimes intrapersonal, like dreaming or cognition under the effects of hypnosis, and is not necessarily nonverbal communication. Research has shown that our conscious attention can attend to 5-9 items simultaneously. All other information is processed by the unconscious mind. Usually our unconscious communication and unconscious behaviour are influenced or dictated by our culture. Communication b ...

Contact lenses (also known simply as "contacts") are lens placed on the cornea of the eye usually, but not always for corrective purposes. They serve the purpose of conventional glasses, but are very light and conveniant, sitting directly on the eye. Contact lens - History. Leonardo da Vinci first proposed the idea of applying a corrective lens directly to the surface of the eye as early as 1508. Similar concepts surfaced from René Descartes in 1636, but it was not until 1887 that the German physiol ...

Conjunctivitis (commonly called "pinkeye") is an inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids), often due to infection. There are three common varieties of conjunctivitis, viral, allergic, and bacterial. Other causes of conjunctivitis include thermal and ultraviolet burns, chemicals, toxins, overuse of contact lenses, foreign bodies, vitamin deficiency, dry eye, dryness due to inadequate lid closure, exposure to chickens infected with Newcastle disease, epithelial dysplasia (pre-cancerous changes), and ...

A corrective lens is a lens worn on or before the eye, used to treat myopia, hypermetropia, astigmatism, and presbyopia. The most common types of corrective lenses are spectacle lenses and contact lenses. Intraocular lenses are also beginning to become common. Myopia (short sightedness) requires biconcave or diverging lenses, whereas hypermetropia (long sightedness) requires biconvex or converging lenses. In some cases, mild farsightedness can be treated with simple magnifying lenses or "reading glasses". However, an optometris ...

A catatonic stupor is a motionless or apathetic state in which one remains oblivious to external stimuli. Motor activity is limited to near non-existent. Individuals avoid bathing and grooming, make little or no eye contact with others, may be mute and rigid, and initiate no social behaviors. This psychiatric symptom is listed in the Diagnostic and Statistical Manual of Mental Disorders and can point towards schizophrenia (catatonic-type), post-traumatic stress disorder, and other mental health illnesses.

Blepharitis is an eruption producing inflammation of eyelids and eyelashes. It is characterized by white flaky skin near the eyelashes. Blepharitis usually causes redness of the eyes and itching and irritation of the eyelids. There are two types. One, anterior blepharitis affects the front of the eyelids near the eyelashes. The causes are seborrheic dermatitis (similar to dandruff) and occasional infection by Staphylococcus bacteria. Two, posterior blepharitis affects the back of the eyelids, the part that makes contact with th ...

Different cultures through history have depicted blindness in a variety of ways; among the Greeks, for example, it was a punishment from the gods, for which the afflicted individual was often granted compensation in the form of artistic genius. Judeo-Christian literature positioned blindness as a flaw; only through a cure could God’s love be made manifest, when the scales would fall away from the eyes of an afflicted individual upon contact with a holy man or relic. Almost without exception in early literature, blind people could bring this condition down upon themselves through sin or trespasses against ...

Urticating hairs are one of the primary defense mechanisms used by tarantulas. This term refers to the barbed hairs that cover the dorsal and posterior surface of the tarantula's abdomen . Many tarantula species will frequently kick hairs off their abdomens, directing them toward potential attackers.

Eye - The orbit. In many species, the eyes are inset in the portion of the skull known as the orbits or eyesockets. This placement of the eyes helps to protect them from injury. Eye - Eyebrows. In humans, the eyebrows redirect flowing substances (usually rainwater) away from the eye. Water in the eye can alter the refractive properties of the eye and blur vision. It can also wash away the tear fluid - along with it the protective lipid layer - and can alter corneal physiology, ...

In most vertebrates and some mollusks the eye works by allowing light to enter it and project onto a light-sensitive panel of cells known as the retina at the rear of the eye, where the light is detected and converted into electrical signals, which are then transmitted to the brain via the optic nerve. Such eyes are typically roughly spherical, filled with a transparent gel-like substance called the vitreous humour, with a focusing lens and often an iris which regulates the intensity of the light that enters the eye. The eyes of cepha ...
