Alfred Bielschowsky
Alfred Bielschowsky (December 11, 1871 – April 5, 1940) was a German ophthalmologist. His specialty was physiology and pathology of the eye, particularly in regards to research of eye movement, space perception and diagnosis of oculomotor anomalies. Bielschowsky was born in Namslau (Namysłów), Prussian Silesia. After attending the Königliches Katholisches Gymnasium of Glatz (Kłodzko), he studied medicine at the University of Breslau (Wrocław) and at the University of Heidelberg. At Heidelberg he was a student of ophthalmologist Theodor Leber (1840-1917).

Ewald Hering
Karl Ewald Konstantin Hering (5 August 1834 – 26 January 1918) was a German physiologist who did much research into color vision, binocular perception and eye movements. He proposed opponent color theory in 1892. Born in Alt-Gersdorf, Kingdom of Saxony, Hering studied at the University of Leipzig and became the first rector of the German Charles-Ferdinand University in Prague.

Racial Policy Of Nazi Germany
The racial policy of Nazi Germany was a set of policies and laws implemented in Nazi Germany under the dictatorship of Adolf Hitler, based on a specific racist doctrine asserting the superiority of the Aryan race, which claimed scientific legitimacy. This was combined with a eugenics programme that aimed for racial hygiene by compulsory sterilization and extermination of those who they saw as '' Untermenschen'' ("sub-humans"), which culminated in the Holocaust. Nazi policies labeled centuries-long residents in German territory who were not ethnic Germans such as Jews (understood in Nazi racial theory as a "Semitic" people of Levantine origins), Roma (also known as Gypsies, an "Indo-Aryan" people of Indian subcontinent origins), along with the vast majority of Slavs (mainly ethnic Poles, Serbs, Russians etc.), and most non-Europeans as inferior non-Aryan subhumans (i.e. non-Nordics, under the Nazi appropriation of the term " Aryan") in a racial hierarchy that placed the ' ...

Eye Muscles
The extraocular muscles (extrinsic ocular muscles), are the seven extrinsic muscles of the human eye. Six of the extraocular muscles, the four recti muscles, and the superior oblique muscle, superior and inferior oblique muscles, control Eye movement, movement of the eye and the other muscle, the Levator palpebrae superioris muscle, levator palpebrae superioris, controls eyelid elevation and depression, elevation. The actions of the six muscles responsible for eye movement depend on the position of the eye at the time of muscle contraction. Structure Since only a small part of the eye called the Fovea centralis, fovea provides sharp vision, the eye must move to follow a target. Eye movements must be precise and fast. This is seen in scenarios like reading, where the reader must shift gaze constantly. Although under voluntary control, most eye movement is accomplished without conscious effort. Precisely how the integration between voluntary and involuntary control of the eye occu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Braille
Braille (Pronounced: ) is a tactile writing system used by people who are visually impaired, including people who are blind, deafblind or who have low vision. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era. Braille characters are formed using a combination of six raised dots arranged in a 3 × 2 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
