Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

People From Bílina
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Julius Hirschberg
Julius Hirschberg (18 September 1843 – 17 February 1925) was a German ophthalmologist and medical historian. He was of Jewish ancestry. In 1875, Hirschberg coined the term "campimetry" for the measurement of the visual field on a flat surface (tangent screen test) and in 1879 he became the first to use an electromagnet to remove metallic foreign bodies from the eye.Manage Account - Modern Medicine at www.ophthalmologytimes.com In 1886, he developed the for measuring strabismus

Anton Elschnig
Anton Elschnig (22 August 1863 – 1939) was an ophthalmologist born in Leibnitz, Austria. In 1886, he received his medical doctorate at the University of Graz, and later worked as an assistant at ophthalmology clinics in Graz and Vienna. In 1892 he obtained his habilitation at Graz, and from 1907 to 1933 was a full professor and head of the eye clinic at the University of Prague. He is best known for performing corneal transplants in the early days of keratoplasty, being credited with developing a method introduced by Arthur von Hippel (1841-1916). (bibliography) Elschnig described this surgical procedure in the "Archives of Ophthalmology" (1930, 4: 165–173). He was the publisher of the second and third editions of the Graefe- ...

Keratitis
Keratitis is a condition in which the eye's cornea, the clear dome on the front surface of the eye, becomes inflamed. The condition is often marked by moderate to intense pain and usually involves any of the following symptoms: pain, impaired eyesight, photophobia (light sensitivity), red eye and a 'gritty' sensation. Classification (by chronicity) Acute * Acute epithelial keratitis * Nummular keratitis * Interstitial keratitis * Disciform keratitis Chronic * Neurotrophic keratitis * Mucous plaque keratitis Classification (infective) Viral * Herpes simplex keratitis (dendritic keratitis). Viral infection of the cornea is often caused by the herpes simplex virus (HSV) which frequently leaves what is called a 'dendritic ulcer'. * Herpes zoster keratitis, associated with herpes zoster ophthalmicus, which is a form of shingles. Bacterial * Bacterial keratitis. Bacterial infection of the cornea can follow from an injury or from wearing contact lenses. The bacteria involved ...

Nystagmus
Nystagmus is a condition of involuntary (or voluntary, in some cases) eye movement. Infants can be born with it but more commonly acquire it in infancy or later in life. In many cases it may result in reduced or limited vision. Due to the involuntary movement of the eye, it has been called "dancing eyes". In normal eyesight, while the head rotates about an axis, distant visual images are sustained by rotating eyes in the opposite direction of the respective axis. The semicircular canals in the vestibule of the ear sense angular acceleration, and send signals to the nuclei for eye movement in the brain. From here, a signal is relayed to the extraocular muscles to allow one's gaze to fix on an object as the head moves. Nystagmus occurs when the semicircular canals are stimulated (e.g., by means of the caloric test, or by disease) while the head is stationary. The direction of ocular movement is related to the semicircular canal that is being stimulated. There are two key form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Von Graefe (ophthalmologist)
Friedrich Wilhelm Ernst Albrecht von Gräfe, often Anglicized to Graefe (22 May 182820 July 1870), was a Prussian pioneer of German ophthalmology. Graefe was born in Finkenheerd, Brandenburg, the son of Karl Ferdinand von Graefe (1787–1840). He was the father of the far right politician Albrecht von Graefe (1868–1933). Background At the University of Berlin, Graefe studied philosophy, logic, natural sciences and anatomy, under notable names such as Dove, H. Rose, Müller, and Schlemm, eventually obtaining his medical doctorate in 1847. He continued his studies at Prague, Paris, Vienna and London, and having devoted special attention to ophthalmology, in 1850, he began to practice as an oculist in Berlin. Here, he founded a private institution for the treatment of eyes. During the same year, he received his habilitation with the thesis ''Über die Wirkung der Augenmuskeln''. In 1858 he became an associate professor of ophthalmology at the Charité in Berlin, where in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikhail Mikhailvitch Woinow
Mikhail Mikhailowitsch Woinow, surname sometimes spelled as Voinov (1844 - 1875) was an optimologists from the Russian Empire who worked Austrian Empire and later in Germany. He served as an assistant to Hermann von Helmholtz (1821-1894) and Otto Becker (1828-1890) at the University of Heidelberg and to Carl Ferdinand von Arlt (1812-1887) in Vienna. Later he established an ophthalmologic practice in Moscow, where he also gave lectures at the university. In Vienna he conducted pioneer ophthalmometric research with August Leopold von Reuss (1841-1924) that included studies of corneal astigmatism following cataract extraction. The two men are credited as the first to describe exact ophthalmometric observations on "wound astigmatism". In addition to work in ophthalmometry, Woinow published a number of papers on subjects such as ametropia, the blind spot, binocular vision, color vision Color vision, a feature of visual perception, is an ability to perceive differences between l ...

Visual Field
The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments". Or simply, visual field can be defined as the entire area that can be seen when an eye is fixed straight at a point. The equivalent concept for optical instruments and image sensors is the field of view (FOV). In optometry, ophthalmology, and neurology, a visual field test is used to determine whether the visual field is affected by diseases that cause local scotoma or a more extensive loss of vision or a reduction in sensitivity (increase in threshold). Normal limits The normal (monocular) human visual field extends to approximately 60 degrees nasally (toward the nose, or inward) from the vertical meridian in each eye, to 107 degrees temporally (away from the nose, or outwards) from the vertical meridian, and approximately 70 degrees above and 80 below the horizontal meridian. The binocular visual field is the superimposition of the two monocular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
