Eyepatch
An eyepatch is a small patch that is worn in front of one eye. It may be a cloth patch attached around the head by an elastic band or by a string, an adhesive bandage, or a plastic device which is clipped to a pair of glasses. It is often worn by people to cover a lost or injured eye, but it also has a therapeutic use in children for the treatment of amblyopia. Eyepatches used to block light while sleeping are referred to as a sleep mask. An eyepad or eye pad is a soft medical dressing that can be applied over an eye to protect it. It is not necessarily the same as an eyepatch. History In the years before advanced medicine and surgery, eyepatches were common for people who had a lost or injured eye. They were particularly prevalent among members of dangerous occupations, such as soldiers and sailors who could lose an eye in battle. While stereotypically associated with pirates, there is no evidence to suggest the historical accuracy of eye patch wearing pirates before sever ...

Amblyopia
Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. It results in decreased vision in an eye that typically appears normal in other aspects. Amblyopia is the most common cause of decreased vision in a single eye among children and younger adults. The cause of amblyopia can be any condition that interferes with focusing during early childhood. This can occur from poor alignment of the eyes (strabismic), an eye being irregularly shaped such that focusing is difficult, one eye being more nearsighted or farsighted than the other (refractive), or clouding of the lens of an eye (deprivational). After the underlying cause is addressed, vision is not restored right away, as the mechanism also involves the brain. Amblyopia can be difficult to detect, so vision testing is recommended for all children around the ages of four to five. Early detection improves treatment success. Glasse ...

Rahmah Ibn Jabir Al-Jalahimah
Rahmah ibn Jabir ibn Adhbi al-Jalhami ( ar, رحمة بن جابر بن عذبي الجلهمي; c. 1760–1826) was an Arab ruler in the Persian Gulf region and was described by his contemporary, the English traveler and author, James Silk Buckingham, as 'the most successful and the most generally tolerated pirate, perhaps, that ever infested any sea.' As a pirate, he had a reputation for being ruthless and fearless. He wore an eyepatch after losing an eye in battle, which makes him the earliest documented pirate to have worn an eyepatch. He was described by the British statesman Charles Belgrave as 'one of the most vivid characters the Persian Gulf has produced, a daring freebooter without fear or mercy' (ironically, his first name means 'mercy' in Arabic). He began life as a horse dealer, and he used the money he saved to buy his first ship and with ten companions began a career of buccaneering. He was so successful that he soon acquired a new craft: a 300-ton boat, manned b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strabismus
Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. The eye that is focused on an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia, or lazy eyes, and loss of depth perception. If onset is during adulthood, it is more likely to result in double vision. Strabismus can occur due to muscle dysfunction, farsightedness, problems in the brain, trauma or infections. Risk factors include premature birth, cerebral palsy and a family history of the condition. Types include esotropia, where the eyes are crossed ("cross eyed"); exotropia, where the eyes diverge ("lazy eyed" or "wall eyed"); and hypertropia or hypotropia where they are vertically misaligned. They can also be classified by whether the problem is present in all directions a person looks (comitant) or varies by direction (incomitant). Diagnosis may be made by obser ...

Laser Applications
Many scientific, military, medical and commercial laser applications have been developed since the invention of the laser in 1958. The coherency, high monochromaticity, and ability to reach extremely high powers are all properties which allow for these specialized applications. Scientific In science, lasers are used in many ways, including: * A wide variety of interferometric techniques'' * Raman spectroscopy * Laser induced breakdown spectroscopy * Atmospheric '' remote sensing'' * Investigating nonlinear optics phenomena * Holographic techniques employing lasers also contribute to a number of measurement techniques. * Laser based lidar (LIght raDAR) technology has application in geology, seismology, remote sensing and atmospheric physics. * Lasers have been used aboard spacecraft such as in the Cassini-Huygens mission. * In astronomy, lasers have been used to create artificial '' laser guide stars'', used as reference objects for adaptive optics telescopes.

National Portrait Gallery, London
The National Portrait Gallery (NPG) is an art gallery in London housing a collection of portraits of historically important and famous British people.

The National Portrait Gallery also has regional outposts at Beningbrough Hall in Yorkshire and Montacute House in Somerset. It is unconnected to the Scottish National Portrait Gallery in Edinburgh, with which its remit overlaps. The gallery is a non-departmental public body sponsored by the Department for Digital, Culture, Media and Sport.
