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 ...

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 ...

If one were to explore the philosophical basis of normative ethics to examine where terrorism falls on the moral spectrum, it will become evident that terrorism, sabotage and guerilla tactics are all acts of violence, essentially no different from overt war in the conventional sense.

Terrorist attacks amount to war by stealth, shadowy figures replacing uniformed combatants, attacking innocents to send a message to the real targets who are out of reach.

The Bates Method is a method created at the beginning of 20 th century by Dr. William Horatio Bates, M.D. (1865-1931) . The aim of the Bates Method is to improve vision and restore the natural habits of seeing, which according to Bates have been lost through strain, tension and the resulting misuse of the eyes. Despite the more than 80 years that the Bates Method has been available, it is still a controversial system. Nevertheless, m ...

Argyll Robertson pupils are small, unequal, irregularly shaped pupils that constrict with accommodation but do not react normally to light. This means that while the eyes can focus on objects both near and far, the direct and consensual response to light are reduced or absent. These are usually, but not always caused by central nervous system complications of syphilis. Other related archivesaccommodation, central nervous system, pupils, syphilis

A bondage hood (also called a gimp mask) is a fetishistic hood. It may be made from rubber, PVC, spandex, darlex or leather. It is designed to completely cover the head, and is thus accommodated with an opening at the back to extend the neck hole for adorning - which may be done up with a zip or cord. (Spandex hoods are often stretchy enough to go on without any extension of the neck hole.) Other optional openings include two eye holes (sometimes these can be closed using zips), nostril openings, and a mouth opening (whi ...

Binocular vision is vision in which both eyes are used together. The word binocular comes from two Latin roots, bin for two, and oculus for eye. Having two eyes confers at least four advantages over having one. First, it gives a creature a spare eye in case one is damaged. Second, it gives a wider field of view. For example, a human has a horizontal field of view with one eye of about 150 degrees and with two eyes of about 180 degrees. Third, it gives binocular summation in which the ability to detect faint objects is en ...

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 ...

The lens or crystalline lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to focus on the retina. In humans, the refractive power of the lens in its natural environment is approximately 15 dioptres, roughly one-fourth of the eye's total power. The lens is flexible and its curvature is controlled by ciliary muscles. By changing the curvature of the lens, one can focus the eye on objects at different dis ...

Myopia is a refractive defect of the eye in which light focuses in front of the retina. Those with myopia are often described as nearsighted or short-sighted in that they typically can see nearby objects clearly but distant objects appear blurred because the lens cannot flatten enough. The opposite of myopia is hyperopia or "farsightedness". Myopia is the most common eyesight problem in the world. About one quarter of the adult population in the United States has myopia. In places like Japan, Singapore and Taiwan, as m ...

A day sailer or dayboat is a small sailboat without sleeping accommodations but which is larger than a dinghy. Many dayboats have a small cabin or "cuddy" for storage and to provide a little shelter, but this is generally not large enough to stand in and certainly not to sleep. Dayboats are also distinguished from dinghies by being more stable, and are generally sailed more like a small yacht than a dinghy. For example, although crew weight may well be shifted to increase performance, this is not crucial to stability as it is a dinghy ...

Vision therapy, also known as visual therapy or visual training, is a broadly-defined set of treatment programs related to the improvement of visual health and comfort. Probably, the best known form of vision therapy is orthoptics which treats binocular vision disorders such as amblyopia, strabismus, and double vision or diplopia. Other problems treated with vision therapy include difficulties of visual attention and concentration, which are said to manifest as an inability to sustain focus or to shift focus from one are ...
