Belief in the evil eye is strongest in the Middle East, Asia and Europe, especially the Mediterranean region; it has also spread to other areas like the Americas. In some more areas where light-colored eyes are relatively rare, people with blue eyes are feared to possess the power to bestow the curse, intentionally or unintentionally. Belief in the evil eye features in Islamic mythology; it is not a part of Islamic doctrine, however, and is more a feature of Islamic folk religion. The evil eye is also significant in Jewish folklore; i ...

Attempts to ward off the curse of the evil eye resulted in a number of talismans being resorted to. Painted balls (or disks) painted with a blue circle with a concentric black circle inside representing an evil eye are common talismans in the Middle East. A blue eye can also be found on some forms of the Hand of Fatima (or Hamsa), an amulet against the evil eye in the Middle East. The large eyes often seen painted at the prows of Mediterranean boats are there, traditionally, to ward off the evil eye; the staring eyes return the malici ...

Stories of genies, magic lamps, flying carpets, and wishes contained in tales from the Arabian Nights and other works have been passed down through the generations. Islamic mythology has probably been influenced to a large degree by Arabic mythology. The two differ, in that Islam prohibits sorcery. Many Islamic elders have told their children bedtime stories about a snake that is mentioned in Islamic Hadith as punishment for missing prayer ...

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.

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 ...

Animals with compound eyes have a wide field of vision, allowing them to look in many directions. To see more, they have to move their entire head or even body. The visual system in the brain is too slow to process that information if the images are slipping across the retina at more than a few degrees per second (Westheimer and McKee, 1954). Thus, for humans to be able to see while moving, the brain must compensate for the motion of the head by turning the eyes. Another complication for vision in frontal-eyed animals is the developme ...

There are many diseases and disorders that may affect the eyes. As the eye ages certain changes occur that can be attributed to solely the aging process. Most of these anatomic and physiologic processes follow a gradual decline. With aging, the quality of vision worsens due to reasons independent of aging eye diseases. While there are many changes of significance in the nondiseased eye, the most functionally important changes seem to be a reduction in pupil size and the loss of accommodation or focusing capability (presbyopia). The ar ...

The structure of the mammalian eye owes itself completely to the task of focusing light onto the retina. All of the individual components through which light travels within the eye before reaching the retina are transparent, minimising dimming of the light. The cornea and lens help to converge light rays to focus onto the retina. This light causes chemical changes in the photosensitive cells of the retina, the products of which trigger nerve impu ...

Visual acuity can be measured with several different metrics. Cycles per degree (CPD) measures how much an eye can differentiate one object from another in terms of degree angles. It is essentially no different from angular resolution. To measure CPD, first draw a series of black and white lines of equal width on a grid (similar to a bar code). Next, place the observer at a distance such that the sides of the grid appear one degree apart. If the grid is 1 meter away, then the grid should be about 8.7 millimeters wide. Finally, increas ...

How a complex structure like the projecting eye could have evolved is often said to be a difficult question for the theory of evolution. Darwin famously treated the subject of eye evolution in his Origin of Species: To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible ...

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 ...

The retina contains two forms of photosensitive cells - rods and cones. Though structurally and metabolically similar, their function is quite different, though they are equally important to vision. Rod cells are highly sensitive to light allowing them to respond in dim light and dark conditions. These are the cells which allow humans and other animals to see by moonlight, or with very little available light (as in a dark room). However, they do not distinguish between colours, and have low visual acuity (a measure of detail). This is why th ...

In its current form, the symbol first appeared in the west during the 17th & 18th centuries, but representations of an all-seeing eye can be traced back to Egyptian mythology and the Eye of Horus. 17th-century depictions of the Eye of Providence sometimes show it surrounded by clouds. The later addition of an enclosing triangle is usually seen as a more explicit trinitarian reference to the God ...

The Eye of Providence also appears as part of the iconography of the Freemasons. The all-seeing eye is then a reminder that a Mason's deeds are always observed by the Grand Architect of the Universe. Typically the Masonic Eye of Providence has a semi-circular glory below the eye — often the lowest rays extend further down. Sometimes the Eye is enclosed by a triangle, but here this is seen as a reference to the Freemason's preference for the number three in numerology. Other variations of the symbol can also be found, with the eye itself being replaced by the ...

This is often us, the audience of a certain text, intra-diegetic gaze, where one person depicted in the text who is looking at another person or object in the text, such as another character looking at another, extra-diegetic gaze, where the person depicted in the text looks at the spectator, such as an aside, or an acknowledgement of the fourth wall, or the camera's gaze, which is the gaze of the ...
